Shinnan says she hasn't had sex with her husband for over a year. The husband is said to be a work person who is absorbed in his work and returns on the last train almost every day. Even on holidays, the husband spends his lonely days without being absorbed in his hobby games. Recently, when he talked to his husband, who spared time to eat and played games, he was in a bad mood and even had no conversation. Shinnan, who was amazed at the attitude of his husband, decided to step into the adult world that he had been interested in for a long time, trying to do what he liked.
