He'll Be The Death Of Me....

Its about a girl who moves to a new school and meets a guy.
He pushes her buttons and gets on her very last nerve
but he also sends her butterflies everytime that crooked smile appears on that beautiful face of him.
How can a guy make you feel horrible but also send your head twirling in an instant?
What happens when they are paired together for a project for that horrible Biology class?
What happens when he pushes her to far and she lets her feelings shine through the mask that she hides behind?
What happens when he realizes that he might love her?
