Keisuke, a son-in-law who decided to live with his mother-in-law. However, Keisuke, a dropout, felt distant from his elite father-in-law. One night, he finds his mother-in-law, Sakuya, who is crying and drunk. When I listen to her story, I say that his father-in-law is having an affair. The two comfort each other and drink sake, but Keisuke can't control her reasoning in front of Sakuya, who has passed out.
