Tomina, a married home tutor who used to teach at a cram school before getting married. She resumed her tutoring job for financial reasons but still found herself short on money, leading her to secretly engage in sugar dating. Her husband is a serious workaholic, which is good, but his nightlife is bland and leaves him sexually frustrated. One day, one of her students shows her a smartphone with pictures of Tomina's sugar dating activities, causing her to panic. From then on, she faces a torrent of sexual harassment and coercion, and even the student's father starts treating Tomina as a sex pet.
