A mother and daughter living together find their lives improving after her remarriage. However, the new father, one husband, is a repulsive man who often peeps at them while bathing. At night, they have rough sexual intercourse that leaves the mother moaning loudly, causing distress for the daughter. To escape these daily struggles, the daughter begins an affair with her teacher, Mr. Ando, engaging in passionate intimacy. It seems like a spiteful act against both her stepfather and mother... but little did she know that he would return home unexpectedly during their tryst.
