Top-ranking student Yoshio suddenly confessed to Nishinomiya, but she had no choice but to reject him, as her mind was consumed with exam preparations. However, seeing Yoshio unable to focus on his studies, teacher Furukawa blamed Nishinomiya and directed his anger toward her. Intimidated by Furukawa's abuse of authority, Nishinomiya found herself powerless to resist, and was forcibly made to have sex with Yoshio. The demands grew increasingly excessive, eventually extending to teacher Murata as well. Threatened and coerced by figures in positions of absolute power, Nishinomiya was driven to the depths of despair. Amidst it all, something within her slowly begins to change.
