Marrying a husband who is both weak and impotent may be one of the biggest mistakes in Yuna Shina's life. She is completely the opposite of him, being a liberated woman with extremely high sexual needs. Because of this, their happiness has increasingly deteriorated. The husband only knows how to bury himself in work while Shina secretly goes out to have affairs with other tall and strong men. Although she made the wrong choice from the beginning, she believes this is her opportunity to make amends; if her husband is useless, she must rely on others to satisfy her sexual needs!
