Yoi Takiguchi's classmates have taken to calling her the school's "prince" due to her androgynous looks and laid-back demeanor. This nickname doesn't bother her much, but things change with the arrival of Kohaku Ichimura, another student who's gotten the same label. Kohaku is quite the opposite of what people expect from a "prince," often acting impulsively and doing whatever he wants. Despite his carefree nature, Kohaku's compliments and unusual attention towards Yoi have her feeling flustered and nervous, marking a change in her usual indifference.
