About six months ago, Ozawa Natsumi found herself burdened with a debt of 3 million yen. After having an affair with a former classmate, she was deceived by that man and started going to loan sharks, and before she knew it, her debt swelled. She couldn't possibly tell her husband about this, so Natsumi approaches the neighborhood association chairman, who is famous for being lewd, for advice. As expected, the two became involved physically. However, her affair wasn't just that... "On the nights I'm held by someone other than my husband, I always lose control."
