Chisato was fed up with the nuisance caused by Kojima, a student from her neighborhood. Even when she gently warned him, he would not listen, and would scorn her. If she tried to warn him in a stronger tone, he would retaliate with misogynistic remarks and sexual harassment. Chisato's patience was running out, and she finally decided to punish him. To reform the young man's rotten character and relieve Chisato's stress, she decided to drag Kojima into her house and have him discipline her. It was a harsh punishment that would leave a lifelong trauma in the young man's Kokoro and penis.
