The bodies of a man and a woman were found on the sea in the small town of Haiju in the north of Japan. People's fingers are tied together, like martyrdom, and the deceased is a newlywed nuclear power technician and a young girl in the right place. Going back to the recorder of the protagonist Sakata and Sakata, he went out to explore the reasons for the suicide. However, the families of the wives and teenage girls of the nuclear technology all seem to have kept secrets and acted mysteriously. And Sakata did not know the activities of his exploration, and had already attracted gratitude for himself. As early as the 1970s, Kazuo Kuroki used this piece to explore nuclear power accidents, a small rural population, and the huge financial rights trade behind the development of nuclear energy. After the 311 Fukuo audit in 2011, the popular work of Kazuo Kuroki was rediscovered and accepted at the site of Fuzhou second Nuclear Power Station.
