She's The Man (Gruvia highschool AU)

Disclaimer ALERT!!!!: I don't own Fairy Tail. Hiro Mashima does. This plot is somewhat based on my own. However, the plot is similar to She's The Man. Like how the characters know each other. But other than that, most of the plots have been changed. Like one: Erza was already knew Jellal. 2: ....... NO SPOILERS.
-------
Juvia Lockser is a real badass. She hates girly frilly dresses. And loves playing football. However, since football was regarded as 'only men', the school cut her team.
Until her twin brother, Jellal showed her a way out.
"Where are you going?"
"Crocus, for a couple of weeks"
"What are you going to do about school?"
"I was kind of hoping you could help me with that, could you pretend to be me?"
She takes his place at a new boarding school, Fairy Tail High. She falls in love with her handsome roommate, Gray Fullbuster, who loves beautiful Erza Scarlet, who has a history with Jellal! As if that were not enough, Jellal returns from Crocus ahead of schedule but has no idea that his sister has already replaced him on campus.
Will she end up with her one true love????

Read on and bear with my cringe-worthy plot. And yes. I know how cringing my description already sounds
