Sachiko, Momoko, and Hitsuji, three kids who met and grew up together in an orphanage, continued to live together happily even after leaving the orphanage. Then, one day, Hitsuji loses his life due to a certain incident. Unable to accept this, Sachiko and Momoko dream of living with Hitsuji again and begin to take some unexpected decisions! What awaits them at the end of these precious and fleeting days that begin with the death of a young boy—hope or despair? (Source: Hero's Inc, translated)
