Prior to this, he had suffered a fatal brain trauma, saved his life after being rescued by doctors, and seized the "1/100000000" chance to regain consciousness. After careful recollection, he remembered his name in a trance. Before he was injured, he seemed to be a young man who was keen on painting. He accidentally met the beautiful and innocent clerk Ye Murhui (Takashi Sakai) in the paint shop. The relationship was illusory and beautiful, and he was intoxicated with it for a long time. By chance, he found a piece of brain that seemed to belong to him in the freezer room of the hospital. when Junichi was injured, the brain tissue was seriously damaged, and it was only thanks to the hospital's advanced technology and the brain of the donor that he was able to recover. As everyone knows, what is even more incredible is far from coming. This film is based on the novel of the same name by the famous Japanese reasoning writer Keigo Higano.
