Hirata Yukata became the first man in Japan to publicly acknowledge that he had contracted HIV through homosexual sex. Koreeda’s film is designed as a lament for Yukata, who had a profound impact on the filmmaker. His dying years are not presented as a time of physical deterioration, but rather an evolution of a relationship between two men, one of whom emerged from the process with a markedly changed perspective on the goal of objectivity in nonfiction film.
