Title: I'll Cheer For You

Genre:

Fluff, Romance, Drama, sad-ish

Storyline:

A couple that broke up, a girl that can't get over her ex. Sounds like the usual.

The boy's a football player, as well as a player over girls.

The girl's a nobody, just a victim of that player.

But the girl can't stop cheering him on at the football games.

And the boy doesn't like it.

What will she do?

Join the cheerleader's squad, of course.

+:

It can end there, as a one-shot. Or it can continue on, as she was despised and didn't get in, she got popular and the boy wants her back, etc. etc. etc. Your choice.
