Kanaho, a married home tutor who had taught at a prestigious cram school before getting married, resumed her tutoring job for financial reasons. Her husband is a serious workaholic, but his nightlife is bland and unsatisfying, leading him to commit adultery. One day, a student she was tutoring showed her a smartphone with photos of Kanaho's affair, leaving her unable to hide her shock. From then on, a torrent of sexual harassment and coercion began. Moreover, even her son's friends and father started treating Kanaho as a sex pet.
