Haru is a humble teenage boy. Born with cerebral palsy, he struggles a little more than the average person. His mother passed away during birth, and his father unfairly blames him. On top of that, he's a social reject. When he first meets hitori, given affection he's never had before of course he confides in him. He'd follow the boy anywhere since he offered a bond and protection. But how far does that go until someone crosses a line?
