Yumi, who wanted to return to the days when she was happy somehow, decided to secretly meet a money lender with her husband. "If you want to help your husband, be my woman only on weekends!" From that day on, a humiliating weekend began as a substitute meat peeing place that doesn't end until you get pregnant.
