Husband Yuuya faced utter despair after failing in cryptocurrency investments and business ventures, leaving him with massive debt. Suddenly, his creditors appeared and proposed an additional 5 million yen payment, demanding that his wife, Mitsuki, work for them as collateral. While Yuuya struggled to restart his business, he could only see Mitsuki after making small repayments. In the meantime, Mitsuki fell under the control of the creditors, gradually transforming into a depraved woman. As her mind and body became increasingly corrupted, the story questions the husband's conscience, torn between justice and desire.
