The justice of a former teacher, it was just self-satisfaction. Mikan, a beautiful girl in a uniform, sits alone on a park bench on a weekday afternoon. She is easily misunderstood because she is not good with words and cannot fit in at school. The man who spoke to her was an old man who seemed to be a 'sensible former teacher'. "I'm saying this for your own good." Those words were just the beginning. A kind adult who listens to her worries. An experienced person who should guide her. But the old man's 'justice' gradually becomes distorted. "You need to be taught with your body!" An ego that takes advantage of the weakness of a girl who is not good at expressing herself. It was not education, nor love. It was just a desire to justify others for one's own satisfaction. Crying, frightened, and yet unable to resist. Eventually, the girl's heart and body are stained with pleasure while breaking down――. A pure and innocent female student and a perverted old man who wields distorted justice!
