Tae-woong’s future changes totally after Jeong-kyu’s death. 8 years on, he has become a boxer and changed his name to Deuk-gu. He visits his friend Choong-shik at a hospital and sees Bora threatening to kill herself. He saves her but they do not recognise each other. The next day, they meet again and argue over Choong-shik at the shop where he works. Choong-shik is fired as a result and Deuk-gu goes to Bora’s house to seek redress. He sees her running away and accompanies her to a beach where she mutters softly at her brother’s grave but Deuk-gu mistakes it for her mother’s. Deuk-gu sends Bora home and is humiliated by her dad who thinks Deuk-gu is after their wealth. Bora argues with her dad over Deuk-gu and is ordered to go overseas. She apologises to Deuk-gu at the boxing school and tells him she is going to a faraway place. Bora disappears and her dad sends his man to ask Deuk-gu about her whereabouts. Deuk-gu finds Bora at the beach and stops her from jumping into the sea…

Deuk-gu works as Bora’s driver to pay his mother’s debts and Bora makes things difficult for him. Gun-woo asks to be together with Bora but she rejects him and says him that she is still in love with Tae-woong whom she knew from his younger days. Deuk-gu drives Bora to school but she alights along the way to attend a fashion show. After searching everywhere for Bora, Deuk-gu finally finds and saves her from a hooligan who is harassing her. Deuk-gu’s mother goes to the boxing school and is upset to find out about his life now. Deuk-gu tells Bora that he wants to quit and Bora agrees to go back to school to make him stay. Bora is shocked at Deuk-gu’s performance in school and suspects that he is not whom he seems to be. Bora gradually accepts Gun-woo who is impressed with Deuk-gu’s talent. At the library, Deuk-gu brings up the incident whereby Bora ran away from home during her college days and Bora realises he is that ‘big brother’ whom she has been thinking of day and night.

Bora meets Deuk-gu again on campus. Deuk-gu reassures Bora that he will not love her or think about her again. Bora’s father learns from Gun-woo that Deuk-gu is indeed Tae-woong. He also finds out about Deuk-gu’s romance with Bora. When Bora returns home, her father forbids her to leave the house again. Bora’s father demands that Deuk-gu leave Korea immediately and vanishes from their sight. When Bora learns of her father’s demands, she tells her father that Jeong-kyu’s death has nothing to do with Deuk-gu. In the night, Bora begs her father to allow her to go overseas and to accept punishment on Deuk-gu’s behalf. The next day, she arrives at the hospital to tell Gun-woo that she is leaving to further her studies. Gun-woo tells Deuk-gu about it but the latter says he will not give chase because he should learn how to let go. Deuk-gu heads for the amusement park where he shared happy memories with Bora. As the night beckons and the crowd has dwindled, Bora appears before his eyes…
