Su Hang, who is talented but has no desire to learn, accidentally entered the top class of the third grade of high school - Class Zero.
I discovered that Jiang Hanyu, recognized by the whole school as a good student and good girl, actually also has a heart that breaks free from restraints and yearns for freedom.
While Class Zero was being tortured, murders occurred one after another on campus.
All things are more or less closely related to themselves...
