Jiang Han is most afraid of two people in his life. One is his ex-boyfriend Xie Luheng, and the other is his student Song Simiao...
Song Simiao: Teacher, in five years I will be as old as you. From now to five years from now, you will be the same age as you are now, and I will grow up.
Jiang Han: I won't believe it, and I won't wait. You are just a childish person.
Xie Luheng: Come with me, or I'll stay. You can only choose one.
