As a student teacher taking her first step toward fulfilling her dream, Kaori begins her teaching practicum. However, in the class she's assigned to, there's a prominent student named Takeuchi, a relative of the school's chairman. The teachers turn a blind eye to his misconduct, choosing to ignore his actions to avoid conflict. Unable to comprehend the adults' complacency, Kaori notices Takeuchi's violent behavior and attempts to stop him—only to face consequences far more severe than she ever imagined.
