P.S I hate you

Savanna is a girly/tomboy who has a crazy best friend called Lydia (And she is a girly girl who is obsessed with 1D) but when Lydia wins free tickets to a 1D concert and asks Savanna to go, the only problem is that savanna doesn't like 1D especially Harry styles . She thinks he's a huge flirt. What happens when Harry falls for her at the concert????
