Miho, a beautiful married woman living with her hardworking husband, was juggling a full-time job five days a week along with a part-time position. However, unbeknownst to her husband, she was involved in another relationship, being summoned every night after her part-time shift to a public restroom. An older man, who called her "manager," lured her with sweet words: "Miho, I think I've managed to arrange that hourly wage raise for you..." The acts carried out in the station restroom grew increasingly intense and varied, gradually shaking Miho to her core. While her husband sincerely celebrated his wife's supposed raise, Miho continued to spiral deeper into depravity behind his back, ultimately losing herself completely.
