Four older boys, You Tong, Li Gefei, Xiao Yu, and Chen Yifan, are roommates in dormitory 302 of Qiming High School.
You Tong is a boy with weird behavior. He has excellent grades, but is withdrawn and doesn't like to talk to others. Xiao Yu is particularly caring for You Tong for a special reason, so the two are widely rumored to be a gay couple among the students of Qiming High School. The death of You Tong's mother has always bothered him, but he accidentally discovered that her death was related to his best friend Xiao Yu.
Li Gefei can be said to be a perfect boy. He not only has good grades, but also looks handsome and is popular with girls. Once he was playing with his girlfriend Lin Shiyu in a bar. Afterwards, he realized that Lin Shiyu was not the first night. After the breakup, he discovered that he could not forget Lin Shiyu, but when he wanted to save everything, Lin Shiyu had fallen in love with someone he didn't expect.
Xiao Yu is the nephew of Principal Xiao of Qiming High School. There is a clique in the school, but he is not bad in nature and cares very much for You Tong.
On the surface, Chen Yifan is Xiao Yu's rival, but in fact he regards Xiao Yu as his best brother, and he does not hesitate to fall out with his mysterious brother at critical moments.
