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...

The members of the Host Club plan an event to help Tamaki get over his separation anxiety from the Host Club, and even Haruhi gets in on the action. Will the bonds of friendship between Tamaki and Haruhi become bonds of love?
