Best friends Forever?

Luna Kinley, 17,not your typical nerd or goody-two-shoes. She is kind but rude when needed, definitely not a pushover who you can mess with. Not popular but that was until she met... HIM.

Archer Davies, 17 and yes your typical Badboy. He is the actual opposite of Luna which means that He is rude but kind to his close people, Popular, plays football, NOT a pushover, people look up to him so basically you can say that he is ruling over that school. Last but not least he is a PLAYER.
_____________________________

Luna and Archer were best friends since they were in middle school. Luna was always a quite type who doesn't like attention so she was not popular but that was until she met Archer. The moment they laid eyes on each other they knew they would be best besties in the future.
They grew up and He became a player while she didn't change except for the fact that she became confident, as she quotes, "the only good quality she got from Archer".
What happens when both starts feeling something that tempts them to cross a line that a best friend should never do..
Will they be able to ignore them and stay as best friends Forever?
