I was forced to have an affair with my son-in-law. She was just when Reiko, who sensed that she was interfering with her daughter's couple's child-making, offered to dissolve her cohabitation. Her daughter opposes Reiko not to make her feel lonely, but Reiko knows that if she continues to live with her, she will not be able to refuse her son-in-law because she is hungry for men. But her daughter's kindness cannot be underestimated... As a woman, Reiko connects with her son-in-law, but as her mother, she wishes for her daughter's happiness, and they live together on a tightrope.
