Fang, the owner of a milk-tea-shop, is worried about his son, who is a rebellious teenager. He has just gotten a new school uniform and is now a first-year student at the school where his son is a student. He tells his friend, classmate, and fellow student, Bai Minghao, that he likes his happy looks, but he still feels uneasy when he goes to school. He explains that he has a younger brother, who has a quarrel with his mom and dad, but they don't care about him. He says that his parents love him the most, but that he is their own child, and that they hope that his education will make him an excellent person. He adds that he doesn't know what kind of love between siblings should be like.
