When she was just five-years-old, Youichirou Sumire lost her everything - her parents, her siblings, her desire for happiness and to be someone that everyone will one day remember. Now a recluse and reserved girl, Sumire has no expectations from anyone and wants nothing to do with anyone but her childhood friend, Ootori Kyoya. That is, until an eccentric blond comes swinging into her and her best friend's life, turning it all upside down and presenting them with an 'incredible idea' of starting a Host Club.
