My husband's company went bankrupt. Izumi (Kawagoe) consulted with Ayaka (Fukada), a daughter of a wealthy man who was a close friend in college, for financial assistance, but Ayaka's father dismissed him and Izumi was sold to a secret club. Izumi, who tasted her living hell, decided to take revenge on Ayaka. While serving Ayaka's house as a servant, he was eagerly aiming for the timing of her revenge. Ayaka doesn't know that.
