The rebellious boy Xu Su was on the verge of being dropped out of school. Under the arrangement of his mother and class teacher Wei Zhi, he joined Class 7 and became classmates with the "mathematical genius" Cen Jun.
Xu Su had an inexplicable dislike for top students, and the two had constant conflicts. In order to cause trouble for Cen Jun, he deliberately approached each other, but discovered an unknown secret - Cen Jun seemed to be the feared "mask bully" in rumors, and was also involved in the murder of a primary school physical education teacher.

The two gradually changed from hostility to sympathy.
