A married woman cleaning worker and a new employee have an affair with a different age who is addicted to carnal desires.

Every day... Riku, a dull new employee whose boss yells at him, struggles with all his hard work. One day, he meets Yuko, a cleaning worker at work. Among the plain cleaners, the beautiful Yuko looked particularly shining. From her days at work while being scared of her boss, Yuko's presence made Riku's life more glamorous. As she unconsciously pursues Yuko with her eyes, she accidentally witnesses Yuko undressing, and pushes her down as she does so, perhaps in a way that may be true.
