Ueto, who works at a small obstetrics and gynecology hospital in a certain part of Tokyo, is a beautiful nurse who is serious about her work, and is trusted by both patients and colleagues for her attentiveness and gentle smile. However, she has a secret that even her close colleagues don't know about. She has a bad habit of seducing husbands who come to the hospital by hiding behind her pregnant wife... Men who are full of sexual desire and stress because their wives refuse to have sex with them, telling them, "You can't have sex until you give birth," are in the semen collection room, in the hospital room, right next to the delivery room where the child is being born...and the pain of childbirth. He betrays his wife, who fights with him, and easily falls for Ueto's temptations. Ueto smiles kindly while watching the man's face satisfied with his goofy hair as he surrenders to pleasure. ``When I see a happy couple, I feel like being mean to them...'' Contains four stories of infidelity in the hospital of scum husbands who are caught up in the act of a naughty nurse.
