Taking a husband who is both physically weak and impotent is perhaps one of the biggest mistakes in Yuna Shina's life. She is completely opposite to him, a woman who is open-minded and has a very high sexual desire. Because of this, their happiness is increasingly cracking.

Despite making a wrong choice from the start, she thinks this is an opportunity to correct her mistake, as her useless husband must rely on someone else to meet his sexual needs!
