Xingcheng No. 3 Middle School is located in Xingcheng, Hunan Province, China. It has been established for a hundred years. The purpose of this school is to take in minors who have violated the law for no reason of their own and to raise and educate them until they reach adulthood and take the college entrance examination.
The students in class K2203 were once the most troublesome existence for teachers in the whole school. They were disobedient, unruly and unbecoming. Before Teacher Toya Hirofu took over, he had already persuaded many head teachers to quit. Unfortunately, what Mr. Toya Hirotsuke is best at is controlling these rebellious but conscientious children.
On the first day of the first semester of the senior year of high school, a strange-looking teacher stepped on the podium of class K2203 with leather shoes. He said: "I have very low requirements for you. As long as you are present in every class, then everyone will be admitted to college."
