Disappear

Ako Togawa and her boyfriend Hiroki were enjoying their youth in high school. They visited their childhood friend Yoshio at his casting press factory. After the death of his father, Yoshio gave up high school but continued to study for college. Yoshio envied Hiroki for dating Ako because Ako had been Yoshio's secret love since childhood. One day, three of them agreed to study together in Yoshio's room. While waiting for Hiroki who was coming late, Ako fell asleep.
