Chisato is tired of the troublesome behavior of her neighborhood student, Kojima. Even though she gently warned me, she was dismissive and didn't listen. If you warn her about her strong tone, she will counterattack with misogynistic remarks and sexual harassment. Chisato can no longer tolerate her due to her excessive behavior and finally decides to punish her. She chose this method as a way to repair the young man's rotten nature and also relieve Chisato's stress.
