Okayyy so here you go :3 I've been thinking about this au for a while and thought why not, so here's the first chapter! This is my first time writing a full out story instead of a oneshot, I'm always open for feedback. :D

"Oh god, where is it…." Marco stood in front of his locker, running his hands through his hair out of stress, before digging around the inside again. He had ten minutes left until first period started, and his textbook decided to hide itself within the mess that is his locker. For a straight-A student with a perfectly organized schedule for himself, his locker wasn't much help.

After a few more minutes of rummaging through the books, loose papers and randoms pens around his locker, he grinned when he finally found it, tucking the book under his arm and closing his locker. He turned around, ready to get to his class early- when he bumped into someone, dropping the books in his hands.

He bent down to pick it up, not even noticing who was in front of him, "Oh my god I'm so sorry-" he apologized and looked up, swallowing hard, "-Jean." Jean stared down at him, his brows furrowed slightly, shifting his weight onto one foot as the freckled male got up, holding the books in his hand. Jean crossed his arms over his chest taking a step closer to Marco, his eyes narrowed. He glanced over his shoulder for a second looking at his little posse, who were smirking, waiting for something to happen.

Marco gnawed on his bottom lip, shifting slightly in his spot as he waited to see what Jean would do. Of course he was terrified, Jean was known to get into fights very often- and most of the times, win.

Something about the guy made Jean actually not want to hurt him, as he would usually do. He sighed, knowing his friends would start questioning him if he didn't do something. Putting on a fake scowl, he slammed Marco up against the locker. Marco closed his eyes tightly shut as he did so, feeling pain shoot down his back.

"What's your name, huh?" Jean asked, lifting a hand up, as if he were about to strike, causing Marco to flinch away.

"M-Marco Bott." he stuttered out, opening his eyes slightly as a confused look spread across his face. He saw Jean's raised arm fall back down to his side, letting go of his shoulder and backing away. Marco got up from against the locker, standing in front of Jean again.

"Watch where you're going next time, Bott." he deadpanned, pushing past him and walking down the hallway. Marco stared at him as he walked away, before leaning back against the locker and breathing out a sigh of relief.

Jean clenched his hands into fists as his friends started questioning him as to why he didn't do something to Marco, "Look, guys. Mr. Smith already told me I'd get suspended if I got into another fight this week." he lied. He was saved by the bell before any of his friends asked anymore questions, mumbling a small, "Bye," to them as he walked over to his first class, the earlier events that took place still on his mind.

Marco wasn't able to concentrate as much as he used to during class at all during first period. He occasionally jotted down some notes, trying to focus on what the teacher was saying, but his train of thought would always redirect to Jean. He seemed pretty angry, didn't he? The anger was apparent on his face, and he was ready to, wasn't he? Wasn't he? This and multiple other questions kept on running through his head, until his line of thought was cut off by the bell, and he picked up his bag, catching up with Eren.

"Eren! Hang on!" Marco called out as he ran after him, grabbing his shoulder as he caught up with him, stopping to catch his breath. Eren raised an eyebrow at the taller male as he turned around, staring at him.

"I need to ask you something." Marco started, rubbing the back of his neck awkwardly as he leaned against a locker.

"Yeah?"

"So, uh, you know how you and Jean get into fights together a lot?" he asked, causing Eren to scowl at the mention of Jean's name, but he nodded his head, letting Marco to continue. "Does he ever, you know, not hit you?" he continued.

Eren gave Marco a confused look, "Considering almost every time we see each other it turns out to be a fist fight, I'm pretty sure the answer is obvious. If you're looking for another answer you need to be clearer, dude."

"No, I mean, like, does he ever look like he's going to hit you, and then just, not?" Marco said, furrowing his brows. He wasn't finding it easy to word the question properly. "Like, does he ever choose not to hit you? " he tried to clear up.

Eren had the same confused look as he tried to understand his question, "Um, as far as I'm concerned, every time we fight he always strikes without a second thought, if that's what you're looking for." he answered, giving him a small smile. "Why are you asking me this though? Did he do something to you?" Eren asked, his voice on an edge.

Marco shook his head, "No, don't worry about it. I'm just wondering, that's all. Thanks."

He waved at Eren as he left, walking over to his second class. As far as he was concerned, Marco was almost completely sure that he had been the first guy that Jean actually hadn't picked a fight with. That realization wouldn't stop bothering him for the rest of the day.

Jean walked over to his class for second period, running a hand through his hair as he recollected the events from earlier that day. He walked over to the desk, sitting by his friends, and staring out into the window. He bit the inside of his cheek as he tried to figure out why he treated Marco differently. After all, if it was Eren or someone else he would have punched them on the spot, without even thinking twice. But then, he hesitated before doing anything. He shook the thought away as the teacher walked in, and stared blankly at the teacher as the class went on, his mind keeping on wandering to Marco.

As the class finally ended, Jean swung his bag over his shoulder and walked with his friends out of class, laughing at some joke Connie cracked that he really didn't hear. As they walked down the hall, he looked down at his phone looking through his text messages when he bumped into something. He scowled and took a step back, looking up. His scowl immediately faded as he saw that once again, Marco had bumped into him.

Marco stood there in front of him, shoving his hands into his pockets, his eyes fixed to the ground. Like always, Jean put on his act again, narrowing his eyes as he took a step towards Marco, ignoring their height difference as he looked up at him.

"I thought I told you to watch where you're going." he said, staring right into Marco's umber brown eyes.

Marco looked down at Jean, shifting his weight onto one foot, "I-I know, and I'm sorry." he said. He slowly took a step back, backing away from Jean.

Connie stepped from behind Jean, a smirk apparent on his face, "Oh ho ho, you're gonna get it now Marco." he said, standing beside Jean. Jean held a hand up, signalling Connie to keep quiet.

He took another step towards Marco, "I'll let it pass this time." he said. "But if it happens again you better watch out."

Marco kept quiet and nodded his head, watching Jean as he walked away. He raised an eyebrow and leaned against the locker, staring up at the ceiling.

Again. It happened again.

He bit the inside of his cheek. Now his point had been proven. He was the first guy that Jean hadn't picked a fight with. It was his plan to bump into him, so he had done it on purpose, just to see if Jean just didn't do it because he had no other choice, because of some teacher or something, or because he didn't want to. Plus, it was a risky move, Marco knew it himself. But after seeing Jean pick a fight with another kid earlier today, he knew that the first reason was crossed out, leaving him to see if he actually chose not to hurt him. And he was right, as far as he knew.

But the question still lingered in both Jean's and Marco's mind:

Why?

Ehehehe hope you like it so far :3 Reviews are always appreciated, and yeah!
