Every time Yoi Takiguchi so much as lets out a sigh, her female classmates squeal in admiration and awe. She has been dubbed the school's "prince" by virtue of her boyishly attractive appearance and casual disposition. However, she chooses to be indifferent toward the attention she receives and spends her days normally—that is, until the school's other prince, Kohaku Ichimura, waltzes into her life and calls her beautiful. Kohaku is nothing like a prince—he acts thoughtlessly and does as he pleases. But when he compliments her, Yoi feels flustered, and the way he looks at her gets her all nervous. He is the first boy to acknowledge her as a girl, and her attempts to distance herself prove futile as he seems to have set his sights on her. While Yoi keeps telling herself that it is nothing serious, even she cannot completely ignore the stir Kohaku causes in her heart.
