Joshikou no Ouji-sama to Osananajimi no Jimiko-chan

A story about an orthodox Prince(girl) of a girl's only high school and her childhood friend(plain looking). Don't you agree that plain looking girls who are actually strong willed are really moe??? By the way, the plain girl's full name isn't featured, but it's Tanaka Mitsuru-chan.
