■Kawakami Natami, a faceless demon who aims only for the day of danger of pregnancy by human wives

One day, a letter was sent to Natami, the wife of a woman who dreamed of giving her child to her beloved husband. "Hello, Aka-chan." At the same time, Natami, who is confused with running away from a man in a ginger hat, strips off his clothes and twists him into an unreasonable cock. Natami is presented in the middle with a smile by an unknown man despite the ovulation date. A month after being scolded by fear and hatred, the man appeared again.... The madness of obsession with jealousy, not deceiving, but being deceived by their own genes!
