The comic book for repeat students is the work of Korean author TAPAS. The cartoon tells that Che Zhiyu, a repeat student in Class 2, Grade 3, is a "bad student" that everyone in the class is afraid of, but he doesn't care. He doesn't want to get involved with anyone, and his only goal is to mix until graduation. It happened that Ji Kuizhen, the squad leader with excellent academic performance, was very concerned about him. Just as he gradually began to accept the monitor, the sudden appearance of his old friend Song Zhixian broke the original calm. What kind of past does Che Zhiyu have? What is the relationship between Song Zhixian and him? Where will the feelings of three people go?
