In the middle of a phone call with his wife, a man named Hamasaki moans to himself about his wife's "filthy sex" from behind her back. Hamasaki's wife, Keita, is waiting for her husband to return home, and Hamasaki wonders why her husband would want to have sex with another man when he has sex with a woman he doesn't love. He tells his wife that he's sorry Hamasaki has come all the way to see her, but she's waiting for him at home, so Hamasaki can talk to her about all sorts of things.
