Risa and her close friend Yuko visit a newly opened esthetic salon in front of the station. The salon's owner, Okada, approaches Risa—a pure, beautiful woman exuding the charm of a married woman—and asks her to work for him. But his true intention is to possess Risa's body. As Okada seduces her, Risa becomes increasingly entangled in a passionate and forbidden relationship with him.
