Kodansha USA licensed the In the Clear Moonlit Dusk manga for English release, describing the main premise as:

Yoi Takiguchi has long legs, a deep voice, and a handsome face…in other words, Yoi is such a good-looking guy that most people don’t notice or care that she is, in fact, a girl. Indeed, she’s had the nickname “Prince” for as long as she can remember. That is, until she met Ichimura-senpai…the only person who really seemed to see her for herself. To her surprise, she’s not sure how to handle this new relationship, especially when her newfound friend is a prince himself (and a guy prince, at that). The story of the two high school princes starts here!
