One day, their smooth married life collapsed. A husband operating a restaurant was betrayed by a usury of a friend and forced to go bankrupt with a large debt. Yumi, who wants to go back to the days when she is happy, decided to secretly meet a loan with her husband. "If you want to help your husband, be my woman only on weekends!" From that day, a humiliating weekend began as a place to urinate with meat instead of not ending until you were pregnant.
