Hey, guys! So, this is a new one that I've come up with that I thought would be entertaining to write, at the very least. Levi and Eren are my OTP, at least for Attack on Titan anyways. I hope I have the motivation to continue this one as time goes on, but that will partly depend on my readers. Follows, favorites, and reviews keep me going. The rating may go up in later chapters, but for now I'm not sure what exactly I want to do with this one. Smut is a possibility later on. Let me know if any of you want to see anything specific happen between these two, also. I'm up for suggestions! Well, anyways, happy reading, and I hope you enjoy! -HeartQueenVivaldi

Never Regret

"The only thing we are allowed to do is to believe that we won't regret the choice we made." -Levi Ackerman

Eren was having a rough time wanting to go back to school for his third year of University. His best friend and regular roommate, Armin, wasn't going to be returning with him, rather he would be transferring to a different university better suited for his goals and degree. Eren was staying, though, and many of his other friends already had roommates, so he had to put in for a random one.

This would be the first year that he would be able to afford the bigger dorm rooms where he wouldn't have to share a bedroom with a stranger, and that was one of the only upsides to it. He hated that he didn't know who his roommate would be, and dreaded move-in day. When he received his paperwork telling him which room he was in, he was at least glad that they told him the other male's name: Levi Ackerman. That would be one less awkward conversation to start with.

Eren's sister, Mikasa, and Armin still wanted to help Eren move into his new dorm, and offered their assistance. Eren accepted the help without complaint, and on moving day he had all his things packed and ready to go when they showed up. All they had to do was load it into a car and they were off to the University about an hour away.

Upon arrival to the parking lot behind the building where he would call home for the next nine months, Eren grabbed a duffel bag of clothes, found his room key, and headed into the building to locate his room, leaving Mikasa and Armin to unload the car and organize a little to help them with carrying things up the stairs.

Eren climbed up to the second floor and walked down the hallway, reading room numbers as he went, when he got to room 217 on the right-hand side, he set down his bag and held his electronic key up to the door. When he heard the lock slide out of the way, he turned the handle and opened the door, grabbing his bag and entering. Previously, Eren had stayed in the smaller rooms that didn't have anything but two single beds, two desks, dressers that were built in under the beds, and a small bathroom that contained only a toilet and a sink. Meals were eaten in the cafeteria with everyone else, and showers were communal. This room was the complete opposite. There was a kitchen to his right with a dishwasher and everything. There was a peninsula bar and just beyond that he could see a hallway, where he assumed the bedrooms and bathroom would be. To his left was the living room, equipped with a television, coffee table, recliner chair, loveseat, and a couch.

Until this moment he had hoped he would be the first one there so that he could choose which room he wanted and unpack in relative peace and not under the eyes of a stranger, but there was no such luck. Sitting on the loveseat, watching Eren survey the room, was a dark-haired male that Eren could only assume was Levi. The two stared at each other, and for a moment all Eren could think was 'damn, he's hot'. The brunette couldn't look away from the grey-blue eyes that held him in a trance-like state, and was almost overcome with a desire to touch the hair that looked so soft. The haircut Levi sported perfectly outlined his face, and Eren was suddenly even more nervous, especially when he realized that the raven was glaring at him.

"Oh… ummm… hi...I... I'm Eren." The brunette dropped his bag by the door and walked forward with his hand outstretched. "It's nice to meet…" He never finished his sentence as his foot caught on the strap of his duffle bag and he tripped. Trying to catch himself, the boy took big steps, almost falling on his face as he moved forward, but eventually lost his balance completely and fell right into Levi's lap, the top of his head connecting solidly with a set of very hard abs, and his nose grazing the older man's zipper on his pants. When his momentum stopped, he collapsed on the raven's thighs, and before he knew what was happening, Levi had stood up, pushing Eren off and leaving him discombobulated on his ass in the middle of the room.

"Do you always make such an entrance? Or are you just stupidly trying to mess with me?" Levi glared down at the brunette, who cowered slightly from the look on the older male's face.

"Umm… well… neither… I can be kind of clumsy sometimes, especially when I'm nervous or anxious." Eren scratched the back of his head and stood up. "I'm really sorry. You are Levi, right?"

The raven grunted in return. "Look, kid. This is my last year of university, screw with me and you'll be dead. My usual roommate graduated last year, so I had no choice but to put up with a random one. Your bedroom is the one on the right, don't even think about setting foot in mine, leave my bathroom stuff alone, that's why it's mine, clean up after yourself, and leave me out of your clumsiness, got it? Seriously, I can't stand messy roommates, or ones that won't stay out of my space."

Eren stood there in silence for a moment to make sure Levi was done talking, and then nodded nervously. He turned without another word to retrieve his bag from the doorway, and went to his own room. He considered for a half of a second about opening the left door just to piss off the man behind him, but didn't entertain the idea for fear of having his balls chopped off or something to that effect.

His room was about the same size as the smaller dorms, but there was only one bed, a closet, and a desk, so there was a lot more floor space. It felt much bigger. Placing his bag on the bed, he left the apartment, ignoring Levi on his way out and went back down to the car, where Armin and Mikasa were just finishing up unloading his few things.

Mikasa saw him first and addressed him: "Hey, did you find the room? Is your roommate there?"

"Yes, to both questions." Eren answered back sourly, not bothering to expand on that.

"Well, what's he like?" Armin inquired when he noticed Eren wasn't going to explain anything without some probing.

Eren exploded a little at having to describe his asshole of a roommate. "What a joke! I can't believe I have to room with that piece of shit! For nine months, NINE! I'm going to go crazy living with that, Armin!"

"Come on, it can't be that bad." Mikasa tried to calm him, pulling his hands off Armin's upper arms where he had latched on during his little rant.

"Oh, no. Just you wait, you'll see. Grab a load, let's go! You can meet the asshole for yourself!" Eren yanked another duffle bag up over his shoulder, picked up a box with some books in it and a few picture frames with photos of all his friends and family, and started walking toward the building with Armin and Mikasa scrambling to grab the last few things and follow him.

The two friends had to practically run to keep up with Eren in his pissy mood. When they entered the room Eren went straight to his room, not even bothering to look at Levi, who was now typing on a laptop at the small kitchen table.

Mikasa looked over at the mysterious roommate, put her box on the peninsula, and held out a hand to the man. "I'm Mikasa, Eren's adopted sister, and this is Armin, Eren's best friend." She held a hand out to him and when he didn't take it she dropped her arm back down by her side and glared back at the man. "Well fine then. Have a nice day." She picked up her box, and headed for the room Eren had gone into, pushing Armin in the back to get him to move.

When they entered the room, Mikasa closed the door behind her. "What a jerk. He didn't say one word to me, and I was even polite."

Eren turned around from his spot in front of the desk where he was setting out pictures and putting books on a shelf, and looked at his sister, who was setting her box on the bed. "You know, had I not tripped he probably would have never said a word to me either, but because I fell right into his lap he had no choice but to insult me and practically tell me to stay the hell away from him. What a douche." Eren stood quietly for a minute watching Armin pull some t-shirts out of a duffle bag to put in a drawer in the closet, before he remembered how enraptured he had been by Levi's eyes and hair at first sight. "It's too bad he's so damn attractive. No, scratch that, he's downright sexy. If he wasn't such a dick, his would probably end up shoved up my ass."

Armin laughed at the comment, but Mikasa grimaced. "You know, just because you're gay doesn't mean you need to pull me into it. I really didn't need to know you saw him that way at all."

Armin chuckled again. "Come on Mikasa, he's got a point. The guy is attractive. Even you can admit that. It was a harmless comment. It's not like he was telling you about his sex life, he's just trying to prove a point."

"Yeah, alright." The three friends changed subject and finished unpacking Eren's things. When they had everything done they decided to order a pizza and see if there was anything good on TV.

When they went out to the living room, Levi was nowhere to be seen. Eren silently thanked whatever gods were watching over him in that moment, flopped down onto the rather comfortable couch and flipped on the television, scanning through the channels to see if anything good was on while Mikasa was on the phone with the pizza place. Armin sat next to him and they were soon swept up in a sitcom and munching away happily on a pepperoni pizza, until Levi came out of his room, that is.

The man grimaced and scrunched his nose in disgust at the sight before him. There was an empty pizza box on the coffee table with unfinished crusts left in it along with some crumpled up napkins. "Disgusting…" Eren looked up when he heard the quiet comment.

"Pardon me, what was that?" The brunette snapped when he realized what the other man had said.

"I said you're disgusting. Clean that mess up, you damn brat." Levi spat back at him.

"I'm not a brat, you are, and I'll clean it up in a minute. It's not like I planned on leaving it there for weeks on end. Just let us finish this episode, then I was going to walk them down to the car to see them off and take the box with me. Just chill, would ya?" He turned back to the television and Levi looked suddenly murderous. Mikasa caught the glare and nudged Armin who nodded, knowing exactly what she was thinking.

"You know, Eren, we've already seen this episode, and we really should be going before it gets dark." Armin and Mikasa stood, taking the empty pizza box with them and heading for the door.

Eren paled a little at the sight, but knew they would have to leave eventually, so he stood up with them, and followed them to the door. Mikasa grabbed her purse off the counter by the door and Eren went to open it.

When the door opened Eren was hit over the head by a fist. On the other side was a person that Eren didn't recognize. This person was suddenly frantic as Eren put a hand to the spot where he was just hit. "Oh, my goodness, I'm so sorry. The door just opened as I was about to knock. Are you okay?"

Eren chuckled and looked up to get a better look at the person in the doorway. It was a girl with brown hair pulled back in a ponytail, and glasses over a pair of big, brown eyes. She looked a little crazy, but concern was written all over her face. "Yeah, I'm okay, but may I ask who you are?"

The girl stood up straight now, laughing, all concern vanishing in an instant. "I'm Hanji, Hanji Zoe. Is Levi here?" She looked up over the three heads and spotted the raven in the background. "Which one of you is Eren?" Eren raised his hand as the woman rambled on. "I hope shorty hasn't given you too much trouble, he can be kind of grumpy, but don't worry, you get used to it. Also, when you get to know him he really is a nice guy. He's just full of compassion and he really does care, you just have to learn to read behind that mean old face of his. He's got a temper though, so try not to get on his bad side. He's a real monster when he's angry. I think his height only makes it worse, too. He's so short, you see! I was his roommate all through college until this year, because I graduated!"

In all of Hanji's ranting, and as she continued, no one noticed Levi approaching from behind, he gently pushed Mikasa and Eren out of the way and knocked the woman on top of the head with his fist. "Stop talking, Shit-for-brains, or you'll be the one on my bad side." He stopped talking for just a second, then tacked on. "And don't call me shorty ever again, or I'll slice your tongue out of your mouth and throw it down the garbage disposal, do I make myself clear?"

Hanji nodded sheepishly, cowering slightly from the aura that surrounded Levi in that moment. The woman recovered quickly though, and threw her arm around Levi's shoulders, dragging him through the apartment and to the loveseat, sitting him down. As she started rambling to him, Eren and his friends slipped out into the hall and headed for the car.

"Geez, how on earth does that crazy woman handle him?" Mikasa complained once they got to the stairwell.

"Or better, how does he handle her?" Eren countered. They all laughed at that. The woman, Hanji, seemed like she was a lot like Eren, but even crazier and a lot more hyper. She would be difficult for anyone to handle, especially Levi.

"But can you believe Levi? I swear there's a stick shoved so far up his ass you could smell wood on his breath. For real, he wouldn't even wait a few minutes for us to clean up the box. He's such a tight ass." Eren rambled on, and his friends listened, nodding in agreement. When they reached the car Armin and Mikasa both gave him a hug, and went to get in the car.

Mikasa opened the door, but turned back around to address Eren one more time: "Good luck, Eren. I know it's going to be hard, but like that Hanji girl said, you might get used to it, and you may even find that you two get along better than you think. Just try not to blow up at him, okay?"

Eren nodded, watched as his friends drove away, and went back up to his new dorm room. When he went back in, Levi was missing again, but Hanji was staring at him with her crazy, brown eyes. Eren nodded to her and went to the kitchen to get one of the popsicles he had put in the freezer. He threw the wrapper away, and leaned against the counter, eating in silence. After a minute or so of awkward silence, Hanji approached him, eyes softening.

"Eren, you seem like a nice kid. I like you already and I've only known you for a matter of minutes. I want you to know that what I said earlier is truer than you know. Levi's really a nice guy once you get to know him. After a while you start to realize that he doesn't mean any of the threats, and he really does care, you know… I know he seems like the type of person you'd never get along with, but after a while…. well… that changes." Hanji went quiet for a moment as if debating whether she should continue or not. Eventually she seemed to come to a decision and finished the serious topic with one last sentence: "please…. don't let him push you away… he will try, just don't let him, okay?"

Eren nodded, not quite sure what to say. This girl was very nice, and she seemed to be sincere. He wanted to do what this stranger was requesting, but he didn't know if he would be able to, judging by how things had already played out, but for her sincerity he was willing to try.

The mood changed quickly after that, and the girl's eyes went wide and crazy again as she handed Eren a piece of paper. "That's my cell number, so if you need to ask questions I would be happy to answer them, especially since Levi can be kind of an asshole. First, I'll give you a couple of basics: One, Levi is a clean freak, so keep the place clean and he will be happier. Two, he has what we call a 'resting bitch face', so if he looks mean, just know that it's how he always looks." The girl laughed boisterously at that, and Eren couldn't help but smile at her frivolity, even as Levi walked around the corner, coming from the bathroom looking like he might actually cut off her tongue.

Levi kicked her out quickly after that, telling her to leave him alone and spitting out another threat, and Eren quickly pocketed the piece of paper so that he could input the number into his phone when he got the chance. He figured he might need that later.
