Nanami married a fellow teacher after a workplace romance, and they continue working at the same school. Their careers and marriage are peaceful until one fateful incident. In this adult school role-play, Nanami and her husband witness delinquent adult student Kogure bullying someone in the hall. Because Kogure is the chairman’s grandson, the vice principal warns Nanami to handle things quietly. Her husband Masahiro, a physical education teacher, becomes so worried and angry that he punches and injures Kogure. Kogure then targets Nanami, promising to hide the incident from his grandfather if she obeys him, and she cannot resist his obscene fingers reaching toward her.
