That day, he drives her to her apartment, but ends up having sex with her inside. One morning, she gets into Yamashita's car with a man who looks like a yakuza. That man is Kamiya, someone Yamashita had helped out in the past. Junko, a friend of Yasushi who lives with Yamashita, has a yakuza boyfriend named Shota. Unaware of this, Uke visits Junko's house, confesses his love, and tries to force himself on her...
