Tsumugi decides to sign a sexual treatment contract with investor Nakae on the condition that her husband, Yosuke, who started an investment introduction business, owes 50 million yen. “If I endure it for a month, I can live a happy life with Yosuke again…” However, at this moment, Tsumugi couldn't imagine what she would look like in a month. I can't believe I don't want the contract to end… I couldn't believe that I was drowning in Nakae's cock in front of my husband.
