Logic Doesn't Help

Kaori has a very busy life, she takes care of her autistic brother, and when she's not doing that, she's striving to keep her scholarship at Ouran Academy. One day she accidentally breaks a tea set worth over 10 trillion yen! She's mistaken for a boy and (along with her brother) is forced to become a host. Hikaru x OC. She's not a Mary Sue! Yay!
