Totally Not Jealous
AU. Gray Fullbuster didn't get jealous over girls; it just wasn't his style. At least, he used to be able to say that. Now? Not so much.
After three months of passionless dating, Gray decides to break-up with Juvia. He, along with everyone else at Fairy Tail High, expects Juvia to have a meltdown so extreme that it'll flood the school halls. But when Juvia comes to school the following Monday with guys trailing after her like lovestruck puppies - including Gray's "evil" foster-brother Lyon - Gray starts to experience a concept that until now, has been completely foreign to him - jealousy.
Now Gray's determined to win his ex-girlfriend back and convince her that he's the guy for her. But first he must realize what it means to be a caring and committed boyfriend, and change his standoffish ways. It's a daunting task, but thankfully Gray's friends are there to help him... even if their methods ARE questionable.
