Kiyoko Yoshida, president of Class 2-1, is assigned to lead her class due to her kind-hearted nature. Tsuyoshi Yano, a new student who frequently injures himself, sits next to her, prompting Kiyoko to become concerned about his well-being. As they spend more time together, Kiyoko discovers that Yano's frequent mishaps are largely due to his clumsiness rather than any deliberate action. Consequently, she becomes increasingly invested in caring for his injuries.
