Eri fell in love with her fellow elementary-school teacher Masato, married him, and left work to enjoy a happy life at home. One day she runs into Kimura, a former senior colleague. He says he was forced to resign after a dispute with parents over a bullying case following Eri’s departure. Once energetic and outgoing, Kimura now looks broken, and Eri feels sorry for him. She has no idea that their reunion was carefully planned—or that he will eventually pressure her into a sexual relationship.
