Ikeda is an honor student who has studied diligently to become a doctor. However, recently, I was worried about Kotomi and I couldn't get her study done, and I voyeured Kotomi in class and masturbated in the physical education warehouse during breaks. At that moment, Ikeda panics and hides after sensing her presence. It was Kotomi who secretly called Ikeda without noticing her. Ikeda accidentally eavesdropped on a phone call between her Kotomi and her boyfriend.
