Kunio had his first sexual encounter with Yoko in a hotel. Since then, he couldn't forget her and called the magazine company where she worked many times, but he couldn't get in touch with her. She was holed up in a hotel because Tamai, a writer, was behind on his manuscript. They finally arranged to meet and waited at a cafe bar in Kabukicho, Shinjuku, but Kabukicho held many bitter memories for him. A few years ago, he was unable to do anything while Yumiko, whom he had liked at the time, was being violated in front of him...
