17 year old Harper Ryan has had to put up with her twin brother (Matthew Ryan) and his best friend (Rowan Sharp) since, well, ever. Matthew and Harper have that typical sibling rivalry relationship but they still love each other (just don't tell them that). Matthew and Rowan are the typical popular jock, player type, while Harper likes to keep her life on the down low. Matthew has made it clear that he wouldn't want Harper to ever be with Rowan, which is fine, since Harper has really only seen Rowan as nothing other than just her brothers best friend. But what happens when a game of "would you rather" at a party changes that?
