Uruwashi no Yoi no Tsuki (In the Clear Moonlit Dusk) follows Yoi Takiguchi, a high school girl whose boyishly attractive appearance and casual disposition have earned her the nickname of the school's "prince." Every time she so much as lets out a sigh, her female classmates squeal in admiration and awe, but Yoi herself prefers to act indifferent and spend her days normally, treating the attention as something she can simply ignore. That changes when the school's other prince, Kohaku Ichimura, walks into her life and tells her she is beautiful.
Kohaku is nothing like the polished image his nickname suggests: he acts thoughtlessly and does as he pleases, speaking with a bluntness that leaves Yoi flustered and nervous whenever he compliments her. He is the first boy to acknowledge her as a girl, and even when she tries to distance herself, her attempts prove futile because he seems determined to keep pursuing her. Yoi keeps telling herself that it is nothing serious, yet she cannot completely ignore the stir Kohaku causes in her heart. Their quiet, complicated attraction becomes the center of a romance built on uncertainty, curiosity, and the growing tension between two students who see each other more clearly than anyone else.
