"He is a cat and you are a dog, and yet, why is it that your not chasing him and he is playing with you?" You are Hinamori Amu's older sister who attends Ouran Academy as the only third year that is a commoner. Due to an accident at the school, everyone is sent home for an early break until then. So, you head home. Then you accidentally stumble upon a blue haired boy in your baby sister's bed. That fact that there's STILL tension between you and your younger sister doesn't help. {Neko to Inu = Cat and Dog}
