After six months of living together, the two of them have moved to Boston and are preparing for the university entrance exams. Si says that he misses his father very much, but that he can't really think of love in his mind. He says that the time he spent with him made him believe that he would never leave him again, and that he will always come back to him. He also says that in the past, he didn't notice that he was falling in love with his father until a certain moment. Si tells his mom that he's finished the application for medical school and wonders if he can become a doctor. He's always been stubbornly blaming himself for the accident, but he finally realizes what he wants. He asks his mom if she always wanted to matchmake with him, but her aunt insisted that he and his sister were mismatched, and have a tear mole that's matching with her daughter. Si's grandmother tells him that she used to be a history teacher, but she was never his father's daughter. She says that she may never like Si, but Si is her son. Si asks his father why he is so tall, and he says that it's because of his imagination. Si wishes that he could find his father and teach him how to live his own life.
