Jung Ae is living a perfect life with a successful husband and son, and all her friends are jealous of her. However, Jung Ae still wants to find her ex-husband, whom she has been out of touch with for 30 years. Meanwhile, Eun Sung picks up a photo of her father on the street.

Jung Ae secretly asks her friend for help to find Dong Gu, and her children, Eun Hyuk and Eun A. Eun Sung finally gets a chance to perform on stage for the first time after joining the theater. While Eun Sung practices the role at the park, Sun Woo happens to see her acting.

Following an unexpected response to her soft-spoken words from an invisible presence, Eun Sung hurriedly leaves the park. Meanwhile, Ha Young sets her sights on Sun Woo as a potential boyfriend. As fate would have it, they cross paths, and her scarf accidentally drops in Sun Woo's path. She regards this as an ideal, coincidental moment to initiate their relationship and excitedly anticipates his gesture of picking it up.

Eun Sung crashes into Sun Woo dressed in a cat costume, and a mob of people start taking pictures of her because of her outfit. Sun Woo, who sees her hesitating about what to do, covers her up with his jacket. However, she runs away without saying a word. Later, Sun Woo reports her to the police, hoping to get back his jacket with his wallet and phone.

After causing a huge scene at the theater, Eun Sung quits. However, she regrets it immediately as she is unemployed now. Meanwhile, Ha Young visits a crime scene for her next movie, and Eun Hyuk heads to the same place after getting a report.

Sun Woo and Eun Sung run into each other at the police station. Even though Sun Woo is looking for the cat lady, he cannot recognize her when she's right in front of him. Meanwhile, Eun Sung is worried she might end up in prison as Si Heon is not willing to withdraw the complaint.

Eun Sung talks to Si Heon to persuade him to withdraw his complaint. However, with Ju Ri by his side, Eun Sung has zero chance of getting out of this trouble. Ha Young finally meets Sun Woo in person at the office and already makes an unpleasant first impression.

With Sun Woo's help, Sun Ju posts the truth behind Si Heon on the Internet for Eun Sung. As expected, Si Heon cannot handle the criticism and resentment toward him. Therefore, he calls Eun Sung first to meet up and talk it out. Meanwhile, Dal Yong is about to get a divorce from his wife, and his family is worried about him.

Sun Woo recognizes Eun Sung right away with her phone case. Sun Woo and Eun Sung leave the theater together to find Sun Woo's jacket, which Eun Sung lost. However, they run into another problem, and Sun Woo makes a deal. Meanwhile, Ha Young is disappointed with Sun Woo as he did not show up for the movie.

After finally getting in touch with Sun Woo, Eun Sung's only objective is to return his items. Unfortunately, things are not going smoothly for her. She plans to meet Sun Woo before Eun Hyuk learns more about the girl in the cat costume. Meanwhile, Ki Seok learns that Jung Ae is looking for Dong Gu without keeping him in the loop.

Sun Woo meets up with Eun Sung to get back his jacket but sees her with a male mannequin and gets the wrong idea about her job. Meanwhile, Ha Young becomes furious at Dal Yong after she learns about another divorce he had, and Jung Ae happens to walk by Yoo Dong Gu on the street.

On her way to a bakery to meet with Jung Sook to talk to her about her frustration over Ki Seok, Jung Ae walks right past Dong Gu. Meanwhile, Eun Sung stresses over not getting anywhere in her acting career, and Ha Young tries to blame Eun Hyuk for breaking the heel of her shoes.

Sun Woo and Eun Sung both end up at the movies, watching a film together, though not exactly side by side. They hit it off over a little chat about the movie, bonding over shared interests, until Sun Woo unintentionally touches a nerve for Eun Sung. Meanwhile, Ha Young is laser-focused on getting closer to Sun Woo.

Eun Sung might appreciate a bit of consolation as she anxiously awaits the audition results, feeling disappointed with her performance. Meanwhile, Sun Ju unintentionally overhears her mother and aunt, sparking curiosity about the mysterious guy in their conversation.

Following a less-than-impressive audition, Eun Sung can't shake off thoughts about the stranger who offered encouragement in the park. Yet, upon revisiting the park, Eun Sung discovers her rescuer is nowhere to be found. Meanwhile, Ha Young's dedicated efforts to foster a deeper connection with Sun Woo go all wrong.

Eun Sung coincidentally bumps into Sun Woo while applying for an audition at Cheong Film, and Chun Young learns from Dong Gu that Eun Sung failed her audition and heads over to the theater to see her. Meanwhile, an embarrassing video of Dal Yong exposes what a terrible dancer he is.

Chun Young unleashes her wrath on Eun Sung after learning she got fired from the theater. Eun Sung tells Sun Ju about what happened, and Sun Ju takes it into her own hands to punish Si Heon for what he did. Meanwhile, Dal Yong gets caught sneaking into the house by Ha Young.

Managing to fix Ha Young's shoes, Eun Hyuk returns them to her. While Eun Hyuk imbues each moment related to the shoes with meaning, Ha Young remains uninterested. Meanwhile, Sun Woo uncovers Eun Sung's falsehood about why she was present at the location of their encounter. At the dumpling place, Dong Gu reminisces about days gone by.

Crossing his fingers that it wasn't too late to figure out who he collided with, Dong Gu promptly searches for Jung Ae. However, in the inevitable way desperate situations unfold, he comes up empty-handed. Meanwhile, Eun Sung's sole focus is on her audition at Cheong Film. Determined to make it happen, she whisks Sun Ju away, seeking a favor.

Towed by Eun Sung, Sun Ju finds herself on the brink of a close encounter with Sun Woo at Cheong Film. Unaware of Sun Ju's odd demeanor, Eun Sung proceeds with her ritual involving a good luck charm. Meanwhile, Chun Young and Yoo Dong Gu face suspenseful moments as Eun Hyuk eagerly agrees to check security footage and identify the person who took the stolen dumplings.

It's Eun Sung's big audition day, and she prepares to do her best. However, she runs into a little problem right before the audition. Meanwhile, Sun Ju struggles all on her own to show Eun Sung the extra support Eun Sung needs for the audition.

The whole family consoles Eun Sung after they learn together that she didn't get picked for the role. Meanwhile, Dal Yong hears shocking news from his friend while he waits for the woman he met on a blind date to call. Later, Eun Sung sees a job posting from Cheong Film and contemplates applying. However, Jung Sook also wants to give it a shot.

Eun Sung gets hired as an admin assistant at Cheong Film after a job interview with Ha Young, not knowing she will be working with Sun Woo. Dong Gu is against the idea of Eun Sung joining Cheong Film as an assistant, but she decides to swallow her pride and take the opportunity.

The weight of stress on Eun Sung becomes evident as she struggles to catch her breath upon discovering that Sun Woo is the director at Cheong Film. Sun Woo, in turn, feels a sense of disappointment as he observes her altered behavior toward him in light of this revelation. Eun Sung is eager for the awkwardness to subside and takes the initiative to propose a solution.

While Sun Woo engages in self-encouragement at the park, Eun Sung catches him off guard with an unexpected interruption. Struggling with embarrassment over his spontaneous monologue, Sun Woo hastily provides flimsy excuses. Despite his efforts, Eun Sung perceives his desperation and silently extends a heartfelt wish for good luck. Meanwhile, Ha Young considers approaching Eun Hyuk for crime-related consultations.

Eun Sung happens to find out that Sun Woo is in a difficult situation as she reads a legal document on his desk. Furthermore, Ha Young gives a simple task to Eun Sung, but she ends up losing all the important files of Cheong Film. Meanwhile, Both Ki Seok and Jung Ae get a tip that Dong Gu is in the country.

The moment Jung Ae hears the news about Dong Gu, she wants to start searching for Eun Hyuk and Eun A as soon as possible. However, Jung Sook is the only one who is not happy with the news. Meanwhile, Eun Sung runs around everywhere to restore all the files she lost, and Sun Woo is worried about her.

Eun Sung is supposed to meet a video creator to restore all the lost files, but Sun Woo feels that there is something fishy about this guy. Meanwhile, Eun Hyuk obtains video footage of the dumpling thief, and Jung Sook is hiding something about Dong Gu from Jung Ae and Ki Seok.

The CCTV footage reveals Dong Gu's determined pursuit of a woman, intriguing Eun Hyuk. Eun A's visit to the station with snacks prompts Eun Hyuk to share the story, sparking her curiosity. At the same time, Sun Ju surprises Jung Ae while she goes through baby clothes purchased for Eun A and Eun Hyuk thirty years ago. The intense verbal sparring between Chun Young and Jin Sil continues.

After learning Eun Hyuk is the police officer who was supposed to be her movie advisor, Ha Young frets that he won't help her. Ki Seok shows Jung Ae the photo that Dong Gu's acquaintance had sent him, and Jung Sook, who now knows Dong Gu is in Korea, becomes anxious Jung Ae will find him.

After seeing Eun Sung and Sun Woo talking on the rooftop, Ha Young asks them if they knew each other from before. Jung Ae visits the police station in hopes her children may have registered their DNA samples in case they were looking for her. Meanwhile, Eun Hyuk asks Dong Gu about the woman he chased after in some footage he was looking through.

Ha Young becomes distressed over the Cat that keeps in contact with Sun Woo and starts to investigate who the Cat could be. Min Guk and Ga Ram hold a special event for Eun A. Meanwhile, Eun Hyuk drinks with Dal Yong, who feels deeply betrayed by his friend.

Sun Woo hands over the cat heart to Eun Sung, but she gets upset as it reminds her of a bad memory. Therefore, Sun Woo feels awful for messing up her day. Meanwhile, Ha Young gets infuriated as she figures out who Cat was all along. She starts to interrogate Eun Sung and Sun Woo.

After talking with Ha Young, Sun Woo is confused about his feelings towards Eun Sung. At the same time, Eun Hyuk happens to see Ha Young and Sun Woo together and gets a wrong idea about their relationship. Meanwhile, Ki Seok suggests Jung Ae take a cooking class at Royal Hotel, and Dong Gu finds out that his sworn enemy, who scammed him with his money, is staying at Royal Hotel.

Eun Sung becomes upset at Sun Woo for mistakenly thinking something else about her job profession and storms off, leaving him behind. Jung Sook is shocked when she hears the news of Dong Gu's death from the private detective agency. Meanwhile, the whole family urges Chun Young to use the cooking class tickets they couldn't sell from the things they got from Mr. Park's items.

Jung Ae and Chun Young see each other in the cooking class and are completely shocked. Ha Young asks Eun Sung what made Sun Woo misperceive her while pretending to have a special relationship with Sun Woo. Meanwhile, Eun Hyuk receives Dal Yong's advice over his thoughts regarding Ha Young.

Eun Sung believes Sun Woo is interested in Ha Young and tries to keep her distance from him. Jung Ae can't get over seeing someone who looks exactly like Chun Young in the cooking class and digs deeper into her identity. Meanwhile, Ha Young offers Eun Sung a tempting opportunity to keep her away from Sun Woo.

Sun Woo is disappointed as Eun Sung did not show up for their dinner date. At the moment, Ha Young joins him just as she planned, but he leaves the restaurant right away. Even though Ha Young feels humiliated, she tries to win him back. Meanwhile, Jung Ae and Chun Young meet again at the cooking class.

Eun Sung finds out the message Sun Woo sent has disappeared, and Ha Young tries to come up with another plan to come between them. Meanwhile, Sun Ju gets extremely drunk and is about to pass out at Dong Gu's restaurant, while Sun Woo visits the park where he met Eun Sung for the first time.

While making her way home, Ha Young's path is crossed by a menacing and intoxicated stranger, but she finds her savior in Eun Hyuk. Overflowing with gratitude, Ha Young earnestly thanks him, but her words inadvertently confuse Eun Hyuk. Meanwhile, at the office, Ha Young deliberately obstructs Sun Woo, preventing him from joining Eun Sung on their location-hunting expedition.

Sun Woo rushes over to protect Eun Sung, who screams out in fear. However, they become trapped in the dilapidated factory in frigid conditions without warm clothing. Eun A hears about Min Guk and Ga Ram's story from Chun Young. Meanwhile, Ha Young calls Eun Hyuk after getting into a fight with Dal Yong.

Jung Ae shows Eun Sung how grateful she is for saving Sun Woo. Ha Young also rushes to the hospital to see Sun Woo after hearing about what had happened. She runs into Eun Sung at the hospital but gives her a hard time for letting Sun Woo almost die. Meanwhile, Ga Ram waits for Eun A excitedly.

Eun Sung and Sun Woo meet at the park and confess their feelings toward each other, while Ha Young visits Sun Woo's home to check in on him. Ga Ram waits for Eun A the whole day even though she cannot make it due to work. Min Guk gets upset at Eun A, and she feels terrible for canceling the plan.

Chun Young barges into her restaurant while Eun Sung and Sun Woo are on their secret first date. Jung Ae and Chun Young have a huge fight and cause a scene after the cooking class. Meanwhile, Eun A apologizes to Ga Ram, and Eun Hyuk gets a gift for Ha Young.

Eun Hyuk becomes flustered when Ha Young asks if he has feelings for her, and Jung Ae finds out that the police officer who kindly helped her was Chun Young's son. Meanwhile, Ha Young becomes extremely jealous when she sees how close Sun Woo and Eun Sung have become.

Eun Sung tries her best to resolve the incorrectly ordered coffee and pastries, while Ha Young meets the CEO and insists that Eun Sung gets fired. Meanwhile, Sun Woo figures out that someone intentionally manipulated the order Eun Sung made.

Ha Young becomes nervous that the security footage will reveal her misdeed, and Sun Ju asks Min Guk's coffee shop for part-time employment. Meanwhile, Sun Woo finds Ha Young's alibi suspicious while searching for the person responsible for sabotaging Eun Sung's order.

Ha Young shares what happened at her office with Eun Hyuk, and he advises her to apologize to her colleague. Sun Ju starts working at Min Guk's cafe and gives him a hard time on her first day. Meanwhile, Ha Young musters up the courage and tell her boss the truth.

Eun Sung has no choice but to introduce Sun Woo to her parents since they got caught by Chun Young. Eun Sung and Ha Young decide to let the coffee truck incident slide, but Ha Young is still upset about Sun Woo. Meanwhile, Jung Ae calls Ha Young to talk to her over dinner, and Eun Hyuk runs into Ha Young at Min Guk's cafe.

After learning about Dong Gu's whereabouts, Ki Seok runs into Eun A while snooping around Haha Chicken. Eun Sung senses something wrong in Sun Woo's expression after he hears about Ed Williams, a famous Hollywood director, visiting Korea. Meanwhile, Ha Young has dinner with Jung Ae alone.

Jung Sook heads to the private investigator's office after seeing Dong Gu and Chun Young at Haha Chicken. Dal Yong asks Jin Sil if she knows who the man Ha Young was head over heels for. Meanwhile, Jung Ae and Chun Young get into an accident in the cooking class.

Sun Woo tells his family that he has a girlfriend after feeling uncomfortable when he hears that Jung Ae met with Ha Young without telling him. Ha Young sets up an interview with Ed Williams and Sun Woo without Sun Woo's consent. Meanwhile, Ki Seok puts a tail on Jung Sook to find out what she is hiding.

Disclosing an error from thirty years ago to Ki Seok, Jung Sook prepares to tell Jung Ae the truth. Meanwhile, Sun Ju is astonished to discover that Ga Ram is Min Guk's son. During a press conference with Ed Williams and Sun Woo, Ed shocks the crowd of reporters by dropping a bomb, placing Sun Woo in a highly uncomfortable position.

During Sun Woo's difficult moments, Eun Sung stands by him with unwavering support. Jin Sil is astonished by a picture found by Ga Ram. Meanwhile, the office team grapples with handling negative articles about Sun Woo. Eun Sung actively seeks solutions and learns about Jennifer, a former colleague of Sun Woo, being in Korea.

Eun Sung meets with Jennifer, but she returns without any positive results. Jung Sook attempts to confess what she did 30 years ago to Jung Ae but falters. Meanwhile, an unexpected guest comes to see Eun Sung after getting an earful from Ha Young for not resolving the problem facing Sun Woo.

Jung Ae isn't too pleased to hear that Eun Sung is Sun Woo's girlfriend, while Ha Young advises Eun Sung, who still looks like she wants to become an actress, to choose between working on the production team or in acting. Meanwhile, Haha Chicken gets picked to air on TV as a tasty neighborhood restaurant to eat at.

Jung Ae finds out where Dong Gu is and rushes over to the chicken restaurant to meet Eun A and Eun Hyuk. Jung Sook also heads to the restaurant to meet Dong Gu before Jung Ae. Meanwhile, Eun Sung wants to audition for Sun Woo's new film, but she hesitates as she has to leave the team to participate.

Dong Gu and Jung Ae clear up the misunderstandings and realize Jung Sook was the one who split them from each other. Dong Gu and Chun Young finally let Eun A and Eun Hyuk know about their birth mother, but Eun A is not fond of the news.

Eun Hyuk and Eun A struggle to come to terms with the fact that Chun Young is not their biological mother. Before anything unfolds, Chun Young takes the initiative to confront Jung Ae, leading to a heated exchange between them. Meanwhile, Ha Young senses that something is amiss with Eun Hyuk and offers a listening ear if he needs to talk.

Chun Young becomes sad when Eun Hyuk tells her he wants to meet his biological mother. Ha Young tells Eun Sung, who is contemplating whether or not to audition for Sun Woo's movie, to give up on the audition for Sun Woo's sake. Meanwhile, Eun A gets mad at Eun Hyuk for wanting to meet their biological mother.

After meeting his biological mother, Jung Ae, Eun Hyuk asks Dong Gu why he divorced her. Eun Sung tells Sun Woo that she will pass on the audition this time and stick to her current role in the office. Meanwhile, Ha Young learns that Sun Woo is the eldest son of KS Foodville and calls Jung Ae.

Eun Sung becomes flustered after experiencing how cold Jung Ae was to her compared to Ha Young. Sun Ju shows her interest in Min Guk and gets into a war of nerves with Eun A. Meanwhile, Jung Ae becomes impatient waiting for Eun A and heads to Haha Chicken to see her.

Eun Hyuk gathers the courage to express his emotions to Ha Young, but the timing couldn't be worse, as Ha Young is a bit too inebriated to take it seriously. Eun A discovers that Chun Young played a role in Jung Ae and Dong Gu's divorce and decides to meet Jung Ae. Meanwhile, Eun Sung accidentally overhears a conversation between Ha Young and her colleague.

Eun A discloses her desire to reunite with her biological mother, aiming to make up for the three decades they spent apart. Dong Gu and Chun Young, though taken aback, recognize their lack of influence over her choice. Meanwhile, Eun Hyuk anxiously awaits Ha Young's call following the previous night's incident. Eun Sung discovers she initially secured the role in Director Hwang's audition, only for it to be unexpectedly altered at the last minute.

Eun Sung is utterly shocked when she learns Eun A and Eun Hyuk are from a different mother. Sun Woo and Sun Ju are also stunned that Jung Ae has another son and daughter they didn't know about. Meanwhile, Mr. Kim tells Eun Sung she should audition for Sun Woo's new movie.

Jung Ae and Chun Young have a big argument over Eun A's future, and Jung Sook takes on the full wrath of someone's power trip as she cleans the stairs. Meanwhile, Ha Young becomes apprehensive over Eun Sung's decision to audition or not.

Eun A wants to move into Jung Ae's house, but Eun Hyuk is against the idea as it will hurt Chun Young's feelings. At the same time, Sun Ju declares that she is uncomfortable with her older siblings from another father. Dong Gu tries to persuade Jung Ae, but she refuses to give in to Dong Gu and Chun Young.

Eun Hyuk formally introduces himself to Sun Woo, but their interaction is cut short by an urgent matter that prompts Sun Woo's quick departure. Meanwhile, seizing the moment, Eun Hyuk asks Ha Young out on a date to watch a musical together. In a serious conversation, Eun A and Jung Ae discuss the complexities of their family relationships, with Jung Ae confiding in Eun A about Sun Ju's struggle to come to terms with her half-siblings.

In the audition waiting room, Eun Sung discovers she's in direct competition with Ju Ri for the same actress role. As usual when Ju Ri is in the mix, Eun Sung faces unexpected challenges. Meanwhile, Sun Ju feels completely at ease with Eun A, even after her swift return the day after quitting. Ju Ri is aware of why Eun Sung isn't showing up for her audition turn but chooses to keep it a secret.

Trapped in the washroom, Eun Sung somehow frees herself with assistance and makes it to the audition room promptly. Pouring all her past endeavors into the audition, she leaves no room for regrets. Meanwhile, Jung Ae calls Sun Woo, requesting that he bring his girlfriend home for a meal.

After finding out that Eun Sung is an unknown actress, Jung Ae disapproves of her even more. Eun Sung can't forget what Jung Ae said to her during dinner, and her words weigh heavily in her mind. Meanwhile, Sun Woo argues with Jung Ae over why she doesn't think Eun Sung is the right match for him.

Eun A and Eun Hyuk have a meal with Jung Ae, and Eun Sung's family feels gloomy, especially Chun Young. Sun Ju is shocked to find out who Eun Sung's boyfriend is, and she plans to come between them. Meanwhile, Eun Hyuk is excited to go on a musical date with Ha Young and decides to confess his feelings again.

After Ha Young comes home from meeting Jung Ae and Sun Woo, she feels bad about canceling the plan she had with Eun Hyuk. At the same time, Eun Hyuk is heartbroken as he realizes that Ha Young lied to him to meet Sun Woo. Meanwhile, the result of Eun Sung's audition will be announced, so Eun Sung and her family gather to find out the result together.

Jung Ae invites Eun A and Eun Hyuk over for dinner to introduce them to her family. Meanwhile, it's Eun Sung's first day joining the Hidden Memory team at Cheong Film as an actress, but she is terrified as she runs into Si Heon and Ju Ri.

Eun A storms out of Jung Ae's house furiously because Sun Woo doesn't show up for their dinner arrangement. When Sun Woo finally returns home, Jung Ae asks him what happened in disbelief. Meanwhile, Jung Ae tells Dong Gu to say it to her face when he calls her about Eun A and Eun Hyuk getting stood up.

Dong Gu, Chun Young, Jung Ae, and Ki Seok all gather and raise their voices about the issues revolving around Eun Hyuk and Eun A and what happened 30 years ago. Meanwhile, Sun Woo learns that Eun Sung got dropped from Director Hwang's final audition, and Ha Young tells Jung Ae about Sun Woo's accident while blaming everything on Eun Sung.

Jung Ae invites Eun A and Eun Hyuk over again to celebrate her birthday and introduce Sun Woo and Sun Ju to them. Sun Woo asks Eun Sung to join them for the birthday dinner. Meanwhile, Sun Woo finds out that Si Heon is Eun Sung's ex-boyfriend during the welcome party.

Eun Sung and Sun Woo's family finally meet and find out about the complicated relationship between the two families. Jung Ae tells them to break up right away as she discovers Eun Sung is Dong Gu and Chun Young's daughter. Meanwhile, Dong Gu lets Jung Sook move into the back room of his restaurant without letting Chun Young know about it.

Despite the parents' disapproval, Sun Woo and Eun Sung are not willing to give up on each other and ask Eun A and Eun Hyuk for help. However, Eun A is also against their relationship, and Eun Sung feels hopeless. Meanwhile, Ha Young runs into Eun Hyuk.

Eun Sung's parents find out that Sun Woo's parents called Eun Sung to their house to talk to her about breaking up with Sun Woo, and Sun Woo's parents find out that Eun Sung's parents called Sun Woo over to their chicken restaurant to talk to him about breaking up with Eun Sung. Meanwhile, Eun A witnesses Sun Ju and Min Guk stuck close together, and Jung Ae tells Ha Young to fire Eun Sung from Sun Woo's movie.

Ha Young contemplates how Jung Ae wants her to help remove Eun Sung from Sun Woo's movie, and Sun Ju hears from Jung Sook about why Jung Ae cut ties with her. Meanwhile, Eun A and Eun Hyuk try to convince Eun Sung and Sun Woo that their relationship can't continue.

Even though Sun Woo and Eun Sung promised to get through the challenges together, Eun Sung starts to waver as she sees both of their families suffer because of them. Meanwhile, Sun Ju confesses her feelings to Min Guk, and Si Heon and Ju Ri find out about Eun Sung and Sun Woo's secret relationship.

Cheong Film turns upside down as the report about Sun Woo and Eun Sung's relationship goes public. Eun Sung thinks Ju Ri is the one who reported false information to the press on purpose, but there is no evidence. Meanwhile, Jung Ae wants Sun Woo to release a statement to quiet down the rumor.

To split Sun Woo and Eun Sung up, Jung Ae reveals what happened with Dong Gu and Chun Young 30 years ago. Eun Sung is shocked, and Eun A gets furious at Jung Ae for telling Eun Sung about it. Meanwhile, Jung Ae waits for Eun Sung's answer, and Sun Woo gets ready for the press conference.

Eun Sung tells in a live-broadcast interview that she is not in a relationship with Director Kang and removes herself from the movie, and Eun A reveals to Jin Sil that she has romantic feelings for Min Guk. Meanwhile, Eun Sung tells Sun Woo coldly that they should stop seeing each other.

After learning Eun Sung dropped out of the movie, Ju Ri asks Sun Woo if she could take over Eun Sung's role. Eun A plucks up her courage and tells Min Guk she has feelings for him. Meanwhile, Sun Woo and Ha Young find Ju Ri suspicious of the tip-off to the press and learn why Eun Sung went missing on the day of her audition.

Si Heon's openness dismissed suspicions surrounding Eun Sung's casting and any influence from personal connections. Nevertheless, a return to the previous state of affairs seems improbable. Min Guk uncovers Jin Sil holding on to Hye Yoon's photograph. Meanwhile, Jung Ae wonders about Eun A's lack of communication and decides to give her a call.

Upon discovering that Jung Ae revealed sensitive information to Eun Sung, Chun Young reacts with intensity, delivering a slap to Jung Ae's face. Meanwhile, Sun Woo questions Eun Sung's vehement opposition to returning to the movie from which she was unjustly ousted. Ha Young runs into Eun Hyuk, who anxiously awaits an informant who has yet to appear.

Ha Young is engulfed in a wave of remorse upon uncovering the connection between Eun Sung and Eun Hyuk. Jung Ae and Ki Seok's attempt to arrange a blind date leaves Sun Woo feeling let down. Meanwhile, Chun Young reaches out to Jung Sook for a conversation, catching Jung Sook off guard and prompting her to hastily retreat from the situation.

Sun Woo becomes upset at Eun Sung's cold attitude as she draws a line between them. Chun Young, who already thought the new tenant was suspicious, believes something is going on between her and Dong Gu. Meanwhile, Ha Young worries about Eun Hyuk after hearing news of a murder suspect on the run and then receives a call about Eun Hyuk's injury.

After learning about each other feelings, Ha Young and Eun Hyuk promise to keep their relationship a secret for the time being. Chun Young pressures Dong Gu to kick Jung Sook out of their vacant room. Meanwhile, Min Guk hears that someone from his family sent snacks to Ga Ram's kindergarten.

Hye Yoon's unexpected return surprises Min Guk, while Ga Ram, unfamiliar with her, is puzzled to learn that she's here to see him. Jung Sook faces Eun A and Eun Hyuk directly, offering apologies for the years of time she has taken away from their mother. Meanwhile, Eun Hyuk and Ha Young are having a drink together, possibly indulging in a few too many glasses.

Ha Young wakes up to a surprise as she discovers she's sharing a bed with Eun Hyuk. Shortly after, she receives a call from Jin Sil inquiring about her whereabouts and if she returned home the previous night. Ga Ram questions Hye Yoon about why she has never visited him, asking if it's because she doesn’t love him. Meanwhile, Ji Yeon joins Jung Ae for dinner and openly expresses her interest in Sun Woo.

Chun Young asks Eun Sung what she thinks about Ha Young. Sun Woo goes to Haha Chicken to persuade Eun Sung to rejoin the movie in front of her parents. Meanwhile, Eun Hyuk finds himself in a tricky situation when Ha Young comes early to meet him as he meets with Jung Ae.

Eun Sung returns to the movie and gets reunited with an old friend. Min Guk is delighted to see Ga Ram and Hye Yoon eating tteokbokki together. Meanwhile, Jung Ae finds out Eun Sung rejoined the movie and heads to see her at Cheong Film, but she sees something shocking.

After stumbling upon Eun Hyuk and Ha Young having a sweet moment, Jung Ae fires off a bunch of questions at them. Meanwhile, Min Guk, Hye Yoon, and Ga Ram roll back after a good time, making Eun A and Sun Ju think about throwing in the towel with Min Guk. Eun Sung and Je Ha bump into Sun Woo and Ji Yeon at a restaurant, and they all end up grabbing a meal together.

Hye Yoon explains to Eun A and Sun Ju that the man with her is just her cousin. Yet, despite her clarification, Eun A and Sun Ju can't shake the suspicion that there might be more to their relationship. Meanwhile, Jung Ae and Chun Young share the same objective of separating Eun Hyuk from Ha Young.

Je Ha reveals to Sun Woo that he has developed romantic feelings for Eun Sung, leaving Sun Woo deeply unsettled. Upon arriving at Hye Yoon’s residence, Min Guk unexpectedly encounters her along with Do Chul. Meanwhile, Eun Hyuk and Ha Young endeavor to convince Eun Hyuk's family about their relationship, but Chun Young appears resolute and unlikely to alter her stance.

Hye Yoon is shocked when she sees Ga Ram listening to her conversation over the phone with Do Chul. Chun Young's plan to split Ha Young from Eun Hyuk with the two mothers-in-law approach hits Ha Young hard. However, Dal Yong hears what happened and calls Eun Hyuk over to speak his mind.

Upon receiving a substantial sum of money from Jin Sil, Hye Yoon finds herself caught in a whirlwind of conflicting emotions, feeling compelled to return the money. Meanwhile, Eun A surprises Eun Hyuk by taking Sun Ju to meet Ha Young and Eun Hyuk, without any prior warning. Meanwhile, Eun Sung attends an event with Je Ha, oblivious to the encounter she is soon to have with someone unexpected.

Sun Woo struggles even more to let go of his feelings for Eun Sung when he sees her with Je Ha. When Je Ha criticizes Sun Woo for not being honest about his feelings, Sun Woo confronts him directly. Meanwhile, Eun A and Sun Ju encounter someone who bears a striking resemblance to Do Chul in the neighborhood. Sun Woo spends the night drinking with Eun Hyuk, finding solace in sharing his troubles with someone he can trust.

Sun Woo wakes up at Eun Sung's place after a wild night of drinking. He ends up joining Eun Sung's family for breakfast, where he casually mentions being a year younger than Eun Hyuk, and Dong Gu finds this a bit awkward. Meanwhile, Min Guk calls Do Chul to discuss something about Hye Yoon's mother.

After listening to Do Chul's lie about being in Vietnam, Min Guk visits Hye Yoon's place. Je Ha tells Eun Sung that he has feelings for her. Meanwhile, Sun Woo heads to see Eun Sung in the audition room after telling Jung Ae that he will get back together with Eun Sung.

Eun Sung and Sun Woo start dating again, and Sun Woo straight away lets Jung Ae know about it. However, Eun Sung can't seem to find the right time to tell her parents the truth. Meanwhile, Hye Yoon confesses to Min Guk about why she came back after all these years.

Dong Gu and Chun Young remain steadfastly against Eun Sung and Sun Woo's renewed relationship, despite Sun Woo's heartfelt plea. Meanwhile, Hye Yoon and Do Chul find themselves in a heated dispute over Hye Yoon's decision to return Min Guk's money. The revelation of Hye Yoon's departure for Vietnam comes as a shock to the entire family, disclosed by Min Guk himself.

Ga Ram is moved to tears upon learning he won't see his mother again, prompting Min Guk to feel guilty for subjecting Ga Ram to the pain of losing his mother once more. Upon hearing the news, Jin Sil is consumed by rage toward Hye Yoon for departing without proper farewells. Meanwhile, Sun Woo stands outside Eun Sung’s house without notifying her beforehand.

Aware that they haven't received official approval from Eun Sung's parents yet, Sun Woo conceals himself in a closet upon Dong Gu's unexpected arrival home. Meanwhile, Jin Sil reaches the cafe and unintentionally listens to a discussion between Sun Ju and Jung Sook concerning Hye Yoon's backstory. Ga Ram sets out to search for his mother without informing anyone.

Min Guk searches for Ga Ram everywhere but can't find him. He runs into Eun A and tells her that Ga Ram went looking for his mom and is missing. Meanwhile, the house helper recognizes Jung Ae and tries to convince her that Dong Gu and Chun Young weren't having an affair 30 years ago, saying it was all a misunderstanding.

Ha Young almost vomits in front of Eun Hyuk's parents and realizes she is ill. After visiting the hospital, she tells Eun Hyuk surprising news. Meanwhile, Jung Ae runs into Dal Yong on her way to meet with Ha Young's father and gets into a scuffle.

Jung Ae and Dal Yong are shocked to find out they're Eun Hyuk and Ha Young's parents. Remembering their rocky start, they promise not to approve of their kids’ marriage. But everything changes when Ha Young announces she's pregnant. After the chaos, Jung Ae drunkenly calls Chun Young, blaming her for not keeping Eun Hyuk in line.

The dispute over Dong Gu and Chun Young's affair escalates, prompting Jung Ae to take Sun Woo and Eun Sung to Haha Chicken to resolve it. While there, Chun Young reveals a shocking revelation about Sun Woo, leaving Jung Ae visibly unsettled by her knowledge. Simultaneously, another individual likely to be astonished by the news overhears it.

Sun Woo hides that he knows Jung Ae isn't his biological mother, and he thanks her from the bottom of his heart. Eun Hyuk doesn't know what to do with Chun Young and Ha Young about where he and Ha Young will live after getting married. Meanwhile, Sun Woo gives Eun Sung a congratulatory event for her movie debut.

Sun Woo suffers as he watches Eun Sung, who had tried to save him, in a coma. Eun Sung's family rushes to the hospital at the tragic news and falls to their knees in torment when they see her. Meanwhile, Jung Ae and Sun Ju, who had witnessed the accident, are also full of anxiety and concern.

After reading Eun Sung's delayed text message, Sun Woo sobs by her side as her condition suddenly deteriorates. Meanwhile, Jung Ae and Ki Seok visit Eun Sung at the hospital after worrying about how she severely injured herself by saving Sun Woo, and Dong Gu and Chun Young decide to let Eun Sung be in love with Sun Woo.

Eun Sung regains consciousness, bringing immense joy to Sun Woo. Having experienced the fear of almost losing each other, they express their love freely. Meanwhile, Jung Ae learns of Sun Woo's awareness of their non-biological relationship and wants to have a conversation with him.

After careful thought, Jung Ae wholeheartedly gives her blessing to Sun Woo and Eun Sung's marriage. Simultaneously, Eun Sung's family, alongside Sun Woo and Ha Young, come together to celebrate Eun Sung's recuperation. Meanwhile, Dal Yong and Jin Sil express apprehension about the forthcoming arrangements concerning Ha Young's baby.

Chun Young and Dal Yong's differing opinions on Eun Hyuk and Ha Young's post-marriage residence put Jung Ae in a difficult position. She also has her own ideas on the matter. Eventually, Eun Hyuk and Ha Young feel compelled to go along with Jung Ae's suggestion of living independently on their own.

With Sun Woo's proposal, the two families meet together and agree on having a wonderful joint wedding, except for Jung Ae. However, the two couples, Sun Woo with Eun Sung and Eun Hyuk with Ha Young, get excited about their futures. Meanwhile, Sun Woo and Eun Hyuk formally propose marriage to Eun Sung and Ha Young.

Eun Sung tells Sun Woo's parents that she will live with them after getting married, and Ha Young agrees to live in Eun Hyuk's room after the wedding until the apartment they want to move into becomes available. Meanwhile, Eun Sung and Ha Young try on wedding dresses in a battle of nerves that ricochets onto Sun Woo and Eun Hyuk, driving them mad.

As the two couples walk down the aisle, solidifying their commitment to a lifetime of happiness together, tensions linger between the parents of the bride and groom, casting a shadow over the wedding hall. Meanwhile, Jung Ae experiences a strange sensation as she observes Eun Sung and Je Ha engrossed in conversation. Just before the bride's entrance, Eun Sung suddenly vanishes.

As Hye Yoon watches Ga Ram play at a playground from a distance, she receives a disturbing call from Do Chul. He threatens to reveal all of her secrets to Min Guk in a menacing manner that deeply upsets her. Meanwhile, Sun Woo and Eun Sung have returned home from their honeymoon to Eun Sung's house, where everything now feels new and unfamiliar for her.

Min Guk falls into deep shock after hearing that Ga Ram isn't his biological child. Hye Yoon tells him the truth from six years ago and that she will take care of Ga Ram if he can't accept Ga Ram. Meanwhile, Jung Ae rebukes Eun Sung as her daughter-in-law about the first family dinner for no apparent reason.

After learning that Ga Ram isn't Min Guk's son, Jin Sil interrogates Min Guk for answers and then sobs in agony. Jung Ae sits Eun Sung and Sun Woo down, already disgruntled about them returning home late, and pressures them about having a baby. However, Sun Woo firmly resists Jung Ae's wishes, which irritates her even more.

After seeing Je Ha dropping Eun Sung off in front of the house, Jung Ae warns Eun Sung to act accordingly. Meanwhile, Ga Ram senses something wrong with Jin Sil and makes a heart-rending plea to her. Later, Jin Sil meets Hye Yoon regarding Ga Ram.

Regardless of its veracity, Jung Ae experiences a sense of shame due to the media's portrayal of an unfavorable incident involving Eun Sung, leading her to harbor minimal trust in Eun Sung. Matters escalate when Sun Woo supports Eun Sung, leaving Jung Ae disappointed. Feeling compelled to resolve Eun Sung's predicament, Sun Woo steps out of the house, taking Eun Sung with him.

Sun Woo, in a fit of anger, vows to move out with Eun Sung if Jung Ae continues to show displeasure at her presence at home, especially after witnessing Dong Gu and Jung Ae argue about Eun Sung. Meanwhile, Sun Ju decides it's time to let go of her feelings for Min Guk, a decision that weighs heavily on her heart. Ha Young and Eun Hyuk visit Jung Ae's house, and Jung Ae scolds Eun Sung for not bringing the right tea for Ha Young.

After receiving her diagnosis, Chun Young is taken aback to realize that her sole chance for treatment rests on a transplant. Dong Gu reassures Chun Young that things will work out, and they agree it's best to inform their children about the illness. Without hesitation, all three children and Dong Gu opt to undergo transplant screening tests.

Everyone in Eun Sung's family becomes devastated when they all get a negative match to be Chun Young's liver donor. Sun Woo says he will also get tested to be the donor, but Jung Ae forbids it. Meanwhile, Jung Ae meets with Tto Soon's mom, the lady who had spread rumors of Dong Gu's affair 30 years ago.

Jung Ae apologizes to Dong Gu and Chun Young after learning the truth from Tto Soon's mother about what she said to her 30 years ago regarding Dong Gu's affair with Chun Young. Eventually, Chun Young and Jung Ae clear up the past and reconcile before heading into the operation room.
