Selena is your average nerd tomboy, she's 17 and independent. Dylan is your cliché football player, a man-whore.
But there's nothing cliché about this live story.
Selena made a mistake. That mistake was dating David who has a huge reputation of being in jail. After she quits the relationship he gets out there. David is after Selena.
Then she dates Henry. Everyone thinks he's sweet, but they don't know the truth behind that act. He's an abusive asshole.
Henry destroys Selena's heart, and she gets back at him.
She becomes an ex-tomboy.
People actually take notice of her. Including Dylan. After becoming a ex-tomboy the school gets a bit dramatic at her exposure.
