Mika and Masato are childhood friends and fiancés. One day, a man named Kita, who worked at the same office as Masato, comes to visit. Kita works as a door-to-door cosmetics salesperson, and he insists on purchasing Mikami. Kita owes money to a yakuza group, and he was forced to help out with various Shinogi, including unscrupulous business practices. In order to protect himself, Kita, who has nothing to do, boils his anger and kidnaps Mika, who is alone in the house. A few days later, Masato received a DVD containing the image of Mika, who was tragically tossed around.
