Hi there and welcome to my very first attempt to write a fanfic! So, this was supposed to have a thousand words but it somehow turned into a monster -I don't know what happened- that I will try to update regularly, no promises though. Anyway, this is an Modern AU that does not happen in the One Piece world and the characters do not have any sort of special ability so don't be confused if they act like normal people and also, I know that the age difference between Luffy and Law is seven years but, for the sake of this fic, let's pretend it's just three.

This will be rated T for now but I might change to M in further chapters, I will keep you update if I do.

Please note, english is not my first language so I apologize in advance if you found any sort of mistakes and, if that's the case, I would appreciate you to tell me so I can fix it right away.

Ok I will stop talking now, hope you all enjoy this first chapter ;)

Disclaimer: I don't own anything related with One Piece, nor even the image.

When Law went to college, he was eighteen and had just come out of high school. He got himself a small apartment in the city centre, close enough of his college to go on foot and cheap enough for him to afford on his own –because getting a roommate was totally out of question- and moved. His family was against his choice, said that their house was close enough and that there was no point for him to move out, that he didn't need to move out. But Law needed independence, needed to get on his own, needed his own place; and if they couldn't understand that, Law was shitting for their opinions too. He was eighteen after all; he didn't need other adults knowing about the fraternity parties and giving lectures about safe sex, he didn't need other adults telling him it was too late when he ended up staying until five am studying, he didn't need other adults meddling in his life because now he was an adult himself, or so he thought.

Well, moving ended up being his first mistake.

Not because of the apartment. It was small, yes, but a small kitchen that he would only use when he needed coffee to stay awake whole nights straight to be able to study to his finals; one tiny bathroom with minimal hygiene conditions; one bedroom with a relatively comfortable bed; and a living room with a sofa and desk large enough for him to spread all his papers, books and notes was more than enough for him. And it wasn't like he was going to have a lot of parties or friends over anyway.

The neighborhood wasn't the problem neither, it was actually quite good; it wasn't near of any pub or bar; there weren't any junkies in every corner; and the fire station and police weren't near which meant that there were no police patrols or fire trucks passing late at night, which wasn't exacly a good thing in the security part but meant that Law, having a light sleeper as he had, could sleep at least well enough to pay attention to his classes.

The apartment had, however, three teenage brothers and a loud old man -that Law assumed was their grandfather- as next door neighbors. Three brothers that, for some reason, were always triggering the fire alarm; three brothers with the most extravagant and loud laughs that Law had ever heard –excluding Doflamingo's; three really loud brothers that had parties almost every night and friends coming and going all day; and three brothers who always filled the dustbin shared by the two houses with boxes and boxes of take away and pizza, leaving Law with no space to put his own trash.

In the first three weeks he didn't cared much, he was almost never at home anyway, but several nights without sleeping more than five hours and several days drinking more coffees that his body could handle can bring up the worst of every person –specially of people like Law that aren't the most friendly by nature.

And that was why Law found himself at his neighbors' front door at five pm of a wednesday. That was his second mistake.

Law rang the bell more times than necessary just to show how in a bad mood he was and, when no one came open the door, he knocked with a clenched fist. And some muffled sounds of things falling and swearing later, the door opened revealing a kid with no more that fifteen years of life and with a really messed hair, puffy eyes and pad marks on the face. At least one of us can sleep hein, Law thought.

"Hi?" the kid asked with an hoarse voice and Law realized he had stared for far too long to be considered normal.

Law cleared his throat and instead of replying with an 'hello' first, he choose to go straight to the point and asked: "Where are your brothers?"Yeah good job Law, that doesn't sound creepy at all, he thought to himself.

"Hum why? Do you need something?" he asked looking at Law like he was trying to find out if he was part of the mafia or something.

"Yeah, I need you to make less noise" Law answered and, when the kid's face changed from suspicion to absolute confusion, he remembered that he still hadn't done any formal introduction to anyone in the neighborhood "I live next door" he pointed with his thumb to his door and the kid followed with his eyes and made an 'o' with his mouth that Law only noticed by coincidence and not because he was staring again.

"Ah so you're the mysterious neighbor! I was starting to think that you were some kind of vampire or something since I never saw you around" he said with a grin. Yeah because that makes a lot of sense, Law thought.

"Anyway, I would very much appreciate if you guys made less noise, I can't sleep properly and, trust me, I really need to sleep"

"Yeah I can see that" the kid said and that was Law turn to be confused "What? You look like a panda"

Law rolled his eyes, hard, and started walking to his house, he already made his complaint so there was no point to keep the conversation going.

"Oi, what's your name?" the kid asked when Law put his hand on the knob. He sighed, it would be rude if he didn't introduce himself , right?

"Law" he answered "Trafalgar Law"

"Well, nice to meet you Traffy" the kid said smiling broadly and Law just turned his head to glare at him "I'm Luffy by the way. Welcome to the neighborhood"

Law glared a little longer to show to the kid that he would not tolerate being called Traffy in the future –if they ever talk again, which Law wasn't looking forward to- but when the kid-Luffy just continued smiling at Law like he hung the moon and didn't showed any response to his glare, he just nodded and entered home.

He heard Luffy laugh and closing the door right after, and he found to whom the most hysterical laughter of the brothers belonged.

He buried himself in the books then and didn't stop until past midnight. He killed every thought about Luffy before they could even germinate in his head.

He heard the remaining brothers arriving home and he could clearly hear trough the wall the kid telling them about his complaint and burst into laughter afterwards.

The day after, when Law arrived home at six, the two other brothers –that Law found were named Ace and Sabo- dragged him to their house and convinced him to drink more beers than he should have. He only accepted because the nicer he was, better were the odds of they let him sleep a whole night.

Luffy wasn't home that day, and Law told himself he didn't cared.

And just like that, Law regained his precious eight hours of sleep he needed; decreased the dark circles under his eyes that he thought would never leave his face; stopped drinking an lethal amount of coffee; recovered his 'good grumpy mood'; and stopped glaring at everyone that dared to socialized with him.

Of course there were still the usual parties and a bunch of people going in and out of the house next door but after eleven o'clock everything remained in something resembling silence, even the laughs became lower after that time. Law sometimes wondered if they started making less noise because they were good people that understood his sleep needs or because he looked like he was going to die of exhaustion at any moment when he went ask them to be quieter and they didn't want to be responsible for a death in the neighborhood. Well, whatever it was, Law thought,it worked.

So the most part of Law's murderous aura was sent to the trash and he started to actually leave his home to do something productive out of his living room area and to do things that normal people do like go to the grocery store with a decent face instead of one that explicitly said 'if you dare to even make visual contact with me I will rip your throat'.

And being somewhat friendly and leave his house more often was Law third mistake because he started seeing his neighbors more often and, since Law wasn't rude, making nods to acknowledge their presence every time and sometimes he even stopped to talk to the old lady that lived a little forward.

And that led to the fourth mistake: actual socializing; because now, every time the brothers had some kind of party that could last longer and pass the midnight mark, Law wass warned with at least three days in advance that the things could get loud and, more often than not, Law was also invited. Sometimes he went, when he didn't have class in the early morning or some exam where he needed to study all night long but most of the times he closed himself in some coffee shop that staid 'open until incredibly late' or in the college library until he felt like the party was probably over and that he should get going to be able to sleep for at least four hours.

That may sound weird –Law knows it sounds- because it was his first year of college and he should be getting completely drunk and shitting to the studies like everyone else instead of close himself at home and fry his brain with human anatomy; but he wasn't like that, he wanted to be good at whatever he was doing –or even the best- and pray for all of that to end the quickly as possible so he can have his sleep schedule again.

And when Law wasn't invited to the parties, he was to the pizza nights and videogames or just to see some marathon of some stupid show that he had never ever heard about in his life. And to be honest, he already gave up to say no because they were very persistent when they wanted something, in the most annoying way possible.

So, obviously, Law had been spending great part of his free time in the stupidly gigantic couch of the house next door doing nothing productive whatsoever and eating a ridiculous amount of junk food that he will regret when he gets high diabetes and cholesterol; and somewhere during that time Law told to the brothers what he was studying at the college which was his fifth mistake because, apparently, the three of them belonged to the Top3 disasters walking in two legs and were always looking for any kind of fight and ended up with ridiculous injuries that, with the excuse 'if you want to be a medic, look at this as a free training', Law saw himself being forced to take care of at the most random hours possible.

And that was how Luffy ended up frequenting his home more and with more regularity than Law wanted to admit because, from the three of them, Luffy was the one that got injured more often. And he ended up being so used to Law's help that he started going directly to Law's encounter instead of telling his brothers first which, for some inexplicable reason, Law was proud of.

That was basically how, in his first year living alone, Law committed five mistakes, met and made some kind of friendship with his annoying neighbors and lost endless sleep hours and brain cells.

I hope you enjoyed it, feel free to leave a comment or a PM if you want :3
