Six years after getting married, Saki innocently supported Kousuke's husband. Saki saw her husband, who was struggling day by day to raise funds for the company in the scene of Corona's influence, and asked for help from the Kinmitsu family's father -in -law, a estranged landlord. Kousuke hesitated for hating his greedy father and left home, but the two of them reluctantly went home to his parents. Katsuji, the father -in -law welcomed her, willing to agree to support financial support, but behind it was an evil intention. "My body is a mortgage for her husband's debt."
