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, he, who is hungry for men, will not be able to reject her son-in-law.But her daughter's kindness cannot be underestimated...As a woman, Reiko is connected to her son-in-law, but as her mother, she wishes for her daughter's happiness, and they live together on a tightrope.
