Kousuke was hesitant because he hated his greedy father and left home, but the two of them reluctantly head to his parents' house. Katsuharu, the father-in-law who took her in, readily agrees to financial aid, but there is an evil idea behind this... ``My body is the collateral for my husband's debt.'' My wife is raped by her brutal father-in-law.
