"Say hello to your new baby sister". That was the worst thing that 6 year old Harry Styles had ever heard in his short life. He wanted a baby brother, not a sister. Through out most of his life he hated the little red headed, green eyed girl and she doesn't know why. When he leaves home for the x factor he thinks that he will never see her again. But when he gets a letter that his mum and dad have died leaving his little sister in his care he has no choice but to look after her. Will they ever get along or will he always feel a hatred towards her?
