Too Good To Be True

How do you know when too good is too good to be true? Kacey Jacobs is pretty, smart, and has a heart of gold. She's not popular by any means and she's only had 2 boyfriends her whole life and they both ended in disaster. She has her friends and she's learned who her real friends are.
Scott Davidson plays by his own rules and doesn't hold anything back. He's the lover and the fighter, but nobody has seen the lover side of him except Kacey. They know everything about each other. They've known each other since they were in diapers when his aunt used to babysit them both. They've never told each other how they felt but Kacey is tired of hiding it and feels like she's running out of time since it's both their senior year, and Scott has a girlfriend who Kacey knows is no good for him.
Will they tell each other how they feel or will it stay in the dark?
