Hime Koibito

Hime Koibito is about two girls in an all girls boarding school (like so many other shoujo-ai) and an upcoming Christmas eve dance. Karen whose family owns a public bath is in the middle school and asks Nakayama an "outsider" and new student to the high school to go to the dance with her. Nakayama is bullied and shy, but Karen is outgoing and determined to get Nakayama to go to the dance with her.... (From Manga Fox)
