Nao, a middle-aged bride who lives happily in a single house, had a problem. It was that I lost my business with my husband. And there was a father-in-law living together who was sexually harassing. Nao closed her eyes because of the loneliness of losing her wife, but her father-in-law's sexual harassment escalated with Nao's attitude. One day, Nao's frustration finally reached the limit and finally masturbated in the bedroom, but my father-in-law was secretly watching it.
