Behind the curtain of a small traditional restaurant, an elegant and refined proprietress greets customers with a warm smile. Every guest inside has ordered the special course, creating an atmosphere tinged with secrecy. As night deepens, the intoxicated patrons are led upstairs after closing. Once their kimono are removed, the story begins. Whether this is the proprietress's intention or a scheme by the guests remains a mystery. The relationship between man and woman is not mere sex—it's a fierce, intimate battle. The proprietress lifts her kimono hem, straddles the man, and grinds her hips in an overtly lewd display, her seductive allure piercing straight to the heart. That single moment changes everything.
