Duan Xiao's self-introduction after transferring to another school was humiliated by Ling Yu, which led to resentment. However, he did not expect that the tutor hired by Duan Xiao's mother was Ling Yu's sister. Because her sister was in trouble, Ling Yu became Duan Xiao's tutor. A series of things happened later that made Duan Xiao realize that Ling Yu's inner world was really lonely. They gradually became close and became inseparable friends. They agreed to go to the same university. Unfortunately, Ling Yu broke the appointment. A year later, they met in the same place: "Why didn't you keep the promise?"
Intention: I really like the way you work hard for the people you like.
