Located in a suburban area of the capital region, close to the city, is a luxurious mansion where the Uchida couple live—Mr. Uchida, a department manager at his company, and his wife. Tonight, they're hosting a home party with two of his colleagues. The conversation is lively and cheerful, with his wife Minako proudly sharing stories, captivating her husband's attention completely—he's utterly enchanted. Ignoring the surroundings, he continuously praises her, and the atmosphere of the party gradually begins to shift. At that moment, one of the colleagues leans toward the manager and whispers, "Boss... how about I lure her out for you? Then you can just go ahead and fuck her."
