{-Bad Apple-}

"Oh, Laito, Miss Cordelia looks to be in so much pain....was that Ayato?"
Yui Komori thought it was Laito who pushed Cordelia off of the balcony, she thought that they were monsters.
But what she didn't know is that while it was their fault their mother died, they weren't alone, their was one girl Yui didn't notice whilst dreaming of the Sakamaki Brothers' childhood, a small girl with cream skin, long red hair and beautiful aquamarine eyes, a girl who helped Ayato and the brothers out as much as she could, a girl with a weak presence and the coldest heart of them all, the one who convinced Ayato and his brothers to rid of their abusive mother, a girl who watched it all. The 'Bad Apple' of the family.

Yui didn't notice the same girl observing from the staircase as she attempted to flee the mansion, but who is this girl and why are the brothers so...different in her presence?
