Dayu works at a small obstetrics and gynecology hospital in Tokyo. Although she appears somewhat youthful, she is known for being kind, considerate, and meticulous in her work, making her a renowned beautiful nurse. However, she harbors a secret that not even her close colleagues know: she seduces the husbands of pregnant women who visit the hospital, without their wives finding out… Men whose wives refuse sex with the phrase 'No sex until after giving birth' accumulate sexual desire and stress, and in the semen collection room, in the ward, right next to the delivery room where their wives are fighting through labor pains... they betray their wives and easily succumb to Dayu's temptations. Dayu smiles contentedly as she watches the faces of men who surrender to pleasure with stupid expressions. 'I just feel like being mean when I see happy couples…' This collection includes four stories of worthless husbands entangled by the evil nurse in hospital infidelity.
