My wife, Nanami, who initially did not want to live with her father-in-law, realized that her dream of having a private yoga school could be realized at her parents' house. One day, my father-in-law witnessed a scene in which a guest attacked during a private lesson and mistakenly thought that Nanami was having an affair and extorting money. The father-in-law, who had previously lost his card, continued to commit the crime after each incident. Nanami gradually became dominated by her father-in-law, and even after getting married, she started having a physical relationship with him.
