Key high school experimental class.
This kind of class never only has good students, but also the scumbags who walk into the school in gray shadows.
The head teacher of Class 9 of the 13th Class has a headache. The class president is a bad student and the school tyrant. How to make this combination...
Serious but unmotivated, a scumbag x gangster and very cool, a domineering scholar
It's very boring, you can just watch it.
