Usually, a cliché high school story goes like this: A boy and a girl have known each other since childhood. Good, slightly nerdy girl falls for the football star. But, the football star has a another girl (most probably a cheerleader) constantly flirting with him, and he's most likely flirting back. It takes a while before the good girl and the football star fall in love then BAM! They kiss and they're together. End of story.
Take the nerdy part, the football part, and the cheerleader part and put it all together. This is how it goes.
Luke Hemmings, the football star, and Hayley Thorne, the cheerleader, have known each other since childhood. Except, well, they weren't best friends. They were rivals. Despite their obvious similarities, Luke and Hayley somehow found a way to bicker over something else: The top ranking in Science class.
