A month has passed since Toshio Matsumoto was told he had cancer. In the darkness, what comes to mind is Tomoko Itoi, a former classmate. Toshio fell in love with her, as she treated him without prejudice despite his own baseness. Forty years have passed since then. Now, Toshio is lost in thought alone. Age 53, pancreatic cancer stage 4. In his delusions, he has thoroughly defiled the memory of Tomoko's smile. He couldn't help it. And when he next opened his eyes, Toshio's mind was made up. He would have Tomoko.
