A couple's quarrel breaks out over a trivial matter. When Yuta's wife leaves in anger, his sister-in-law, Luisa, offers to mediate the quarrel. Luisa gently comforts Yuta, who is at a loss as to what to do. Yuta begins to feel strange about Yuta's beautiful appearance, perfect waistline, and perfectly balanced model-like figure, so he runs off to the bathroom, but Luisa bursts in without asking any questions.
