In the Clear Moonlit Dusk 1

Yoi Takiguchi's long legs, deep voice, and handsome face are the perfect recipe for an attractive guy—until people realize she is, in fact, a girl. Dubbed a "prince" by her peers since childhood, Yoi has all but given up on being seen as anything else. That is, until she bumps into Ichimura-sempai, the school's other prince (who's a he) and gets a taste of what it feels like to be seen for her true self. The story of the two high school princes starts here!

Volume 1 of the In the Clear Moonlit Dusk manga series by Mika Yamamori.
