Disappear

Ako Togawa and her boyfriend Hiroki were high school students enjoying their youth together. They visited their childhood friend Yoshio at his family's casting press factory. After his father's death, Yoshio left high school but continued preparing for college. Yoshio harbored secret feelings for Ako, who had been his childhood love, and envied Hiroki for being with her. One day, the three agreed to study together in Yoshio's room. While waiting for the late-arriving Hiroki, Ako fell asleep. Yoshio, peeping at her white panties, lost control and assaulted her. During the struggle, Ako hit her head and lost consciousness. When she awoke, her hands and feet were bound with rope. This marked the beginning of her life as Yoshio's captive. How long will the days of love, desire, and solitary confinement behind closed doors last?
