At 42, Kanae, after 15 years of marriage and with her eldest son now attending a full-time boarding middle school, returned to the workforce at a major skincare company. Immersing herself in her job, she steadily advanced her career. Her husband, a civil servant, spent every weekend from morning to night enjoying sea fishing, leaving Kanae to explore new hobbies suited to her changing life. This led her to the choice of an affair with a younger man. The satisfaction derived from her professional success gradually awakened masochistic desires within her. Beginning with an enjoyment of outdoor exposure, she increasingly expressed her submissive fantasies, socially inappropriate behaviors, and ultimately her longing to become a sex slave.
