"Clumsy little old me wasn't paying attention to my surroundings when I bumped into a hard wall. Wait no! It wasn't a wall, it was (bad boy name) oh crap."
Now you mean to tell me that some high school boys chest feel like a wall.

Alright, thought so. Majority of the time the character ends up bumping into the bad boy so hard that she falls.
HOWWWWW?
Like did you run into that boy. If you were able to fall on the ground the bad boy should have too. But remember for the sake of the plot he needs to be physically strong.
