In this screwball romantic comedy, Haruhi, a poor girl at a rich kids' school, is forced to repay an $80,000 debt by working for the school's swankiest, all-male club—as a boy! There, she discovers just how wealthy the six members are and how different the rich are from everybody else...

Haruhi's top ranking falls and she is in jeopardy of losing her scholarship at Ouran. Each member of the Host Club scrambles to become her tutor, but Haruhi picks a female student, Ayame, to help her. Haruhi's time is now spent with Ayame, who can't stand Tamaki. Can Tamaki charm his way into Ayame's good graces so the Host Club can spend time with their favorite member?
