There was at least one in the grade. - A girl who is abnormally stunted and attracts attention contrary to her will. Natsuki-chan is such a girl. When she goes to school, she walks with a hunched back so that her boobs are not noticeable, and she takes a sick day off from sports days and pools. There's no way she can have a heart-pounding romance at school. The uncontrollable desires of youth have no choice but to hide from everyone and become an uncle in the neighborhood.
