Summary: A new neighbor has just moved into the apartment next door and he's annoying as hell but Dean's too busy thinking about the amazing guy he keeps meeting in his coffee shop to care.

A/N: I just got this idea suddenly while my little sister was watching Spongebob. I was just thinking that oh my god, Squidward's like Cas and Spongebob's really just an annoying version of Dean! Then I was thinking how hilarious it would be if both of them were neighbours and thus this fic! Its my first time writing an AU so I hope its okay! As usual, ENJOY and REVIEW :)

Someone new had just moved into the apartment next to Dean and he was loaded. He hadn't exactly met the guy yet, just met the brother who introduced himself as Gabriel. The guy was short and really annoying and if his brother turned out anything like him, Dean would seriously consider moving out, if he could afford to, that is. The other other guy, however seemed wealthy enough; Gabriel was helping him move in the furniture and damn do they look expensive. Not just that, the dude spent two weeks remodeling the apartment before moving in. From the sounds of it, it seemed to be a big-scale makeover and definitely would have cost a fortune; Dean would know, he tried to get new cabinets for his kitchen and immediately got rid of the idea as soon as he saw the cost if it.

Two weeks of hearing the sounds of constant hammering across the paper thin walls was enough to make Dean annoyed at his anonymous neighbor but seeing the expensive-looking furniture decorating the hallway made him even more so. Every time he decided to leave his apartment, he had to carefully squeeze himself through the hallway and it was freaking uncomfortable. He couldn't wait to meet his neighbor and give him a good piece of his mind.

Dean was tired. It had been a busy day at the coffee shop and his shift didn't seem to end fast enough. Sure he left earlier than he should have, it was only noon but he was sure Jo could manage on her own just for a day. He was exhausted, running a cafe was no easy feat but he sure was glad that he was partners with someone as awesome as Jo. She was a really old friend, almost like a sister to him so it was great to be in business with her.

With a 'ding', the elevator came to a stop at his floor. Dean braced himself for another round of hopping around stray chairs and lamps but was surprised to see the hallway empty of furniture. Looks like Mr. Filthy-Rich had moved in already. He gave a sign of relief, turning the key and walking into his own apartment.

Immediately he walked towards the stereo and turned it on, Led Zepplin blasting through the speakers. Singing along loudly to the chorus Dean fixed himself a sandwich and sat on the couch, savoring his lunch. Suddenly, he frowned as he heard loud banging coming from the wall behind him.

"Turn the volume down!" came a muffled, deep shout from the other side of the wall. "Some people are trying to sleep, you know!"

Dean looked incredulously at his wall clock. "Sleep? What are you, a vampire?" he yelled back. "It's only two in the afternoon!"

"I had trouble sleeping at night," came the muffled reply.

"Well sucks for you then." he retorted.

Dean could hear the slamming of a door and wasn't too surprised when he heard loud knocking on his own front door.

"Get out of the dingy old hole you call an apartment and we can have a talk!" Mr. Filthy-rich yelled.

Dean rolled his eyes and ignored him, increasing the volume to drown out the incessant banging on his door, hoping that the dude would get tired and leave.

True enough, after a few minutes, the knocks slowed down and with a final blow that could have been strong enough to break the door down, he shouted, "You're an assbutt!" With that, the stomping of feet could be heard as the door beside him slammed close again.

Dean snorted, assbutt? Not only was his neighbor some kind of nocturnal monster from hell, he didn't even have the creativity to think of a good swear word for him.

Whatever, Dean thought, the guy's a first grade douche.

And a first grade douche he was for Dean woke up in the middle of the night with yelp as he heard the loud clashing of cymbals from next door, followed by the screech of violins. Deans stomped over to his living room and pounded his fist onto the shared wall between him and his neighbor. "What the hell are you doing playing orchestra music in the middle of the night while I'm trying to sleep?"

"Why, I thought you loved loud music!" came the casual, too smug reply.

"It's four am, Dracula! I've got work in the morning!" Dean growled back.

"Well, sucks for you then."

If Dean wasn't so sleepy, he would have stomped right over and strangled the man with his bare hands, or maybe with a barbed wire, whatever could cause the most pain. Instead, he angrily went back to his room, pillow pressed against his ears as he asked God what he did to deserve such an annoying insomniac as a neighbor.

Dean's head was pounding and his eyelids were fighting to keep open; he felt horrible. He hadn't had a proper good night's sleep for a week, ever since his god-awful neighbor moved in. Just when he thought that he couldn't get any more annoying, he was wrong. The ass-hole got a freaking dog on the second day and it had joined in barking along to the loud music that his neighbor never failed to play in the middle of the night. Dean had gotten accustomed to the big fluffy pink earmuffs that Sam had gotten him as a joke as they helped a little with the noise.

Dean yawned and slumped his head onto the counter. It was just his luck that his night-time worker, Ash had gotten himself too drunk to work and Jo had called in sick because he was now stuck doing the grave-yard shift. Who the heck would want coffee at two in the morning, Dean had argued but Jo firmly told him that they were not going to close their 24-hour cafe at any cost. Dean closed his eyes and gave a loud, tired groan that seemed muffled as his head was still on top of the counter.

"Umm, I'll take it that now's a bad time?" a deep voice hesitated.

Dean startled and jerked his head back, eyes springing open. The first thing that flooded his vision was the color blue. An intense, electric blue of eyes that were staring straight at him. Those eyes were blinking away strands of hair. Oh the hair, it was a messy mop of black that was in a disarray. The man looked like he had just gotten out of bed and dean yearned to run his fingers trough the soft black hair.

"Sorry for startling you."

There it was, the gravel laden husky voice that was spoken from a pair of pink, chapped lips that Dean couldn't help but stare at in fascination.

The man looked sincere as he apologized and Dean couldn't stop the easy smile that took over his face.

"Nah it's okay, it's just been a slow night. What can I get you?"

"Just some green tea would suffice."

Dean busied himself as he got the customer a cup of green tea and placed it at the counter where he had taken his seat.

"One cup of hot green tea for our only customer!"

The man looked up at him and gave Dean a small smile that Dean returned with one of his grins. The next few minutes were quiet as the man took small sips of the steaming hot tea while Dean fidgeted behind the counter. He was bored and there was no one else in the shop for him to attend to.

"So, you're new in town?" he hesitated."I haven't seen you around before."

As soon as the words left his mouth, Dean cringed. God, that sounded like a cheesy lewd pick-up line and Dean was definitely not trying to hit on the man he met just ten minutes ago. Okay, maybe he was, but he didn't want to sound too obvious.

However, the man didn't take it the wrong way, or he simply didn't show it as he nodded to Dean's question. "I've just moved in recently. It's been a week." He then looked at Dean, head tilted as he analyzed his face.

"You look tired," he frowned. "Maybe you should get something to drink too."

Dean self-consciously looked at himself in the reflection of the mirror that hung on the wall beside him. Crap, he did look tired, in fact, he looked downright dead. It was all his stupid neighbor's fault. God, he hated that guy. Sighing, he got himself some coffee and grabbed a stool, facing the customer across the counter.

"Yeah, I've been having a hard time sleeping, my neighbor's a jerk who's life's goal is making sure that I suffer from lack of sleep every night."

The man nodded sympathetically. " I know what you mean. I have insomnia and can only fall asleep in the afternoon but my neighbor plays really loud music," he said, sounding a little annoyed. "He doesn't even have good taste."

Dean chuckled. "Of all the people living in the city, we got the two most annoying people living beside us. We must be really lucky."

The man laughed softly behind the rim of his cup as he drank in the last of his tea. "I should be going now, it's very late."

He stood up to leave and was almost walking out the door when Dean suddenly blurted out, "Wait!"

The man stopped and turned around.

"Umm," Dean hesitated, not sure of what to say. " We, umm- The shop's open in the mornings and afternoon's too!"

Real smooth Dean, he thought to himself as he realized just how stupid he sounded.

The man looked at him and with a twinkle in his eyes, he replied "Of course," before walking out the door.

And just like that, Dean's week turned out pretty awesome after all. Never mind that he was still stuck living next to Mr. Filthy-rich, the biggest asshole that Dean's ever faced, meeting Mr. Blue-eyes made up for it.

Dean didn't want to admit it but for the next few day, he found himself hoping to meet the blue eyed man again. His eyes would keep glancing towards the door every time he heard a customer enter and his heart would sink a bit when it wasn't who he was waiting for. Even during the peak hours when he was too busy to think straight, Dean kept an eye out for that customer.

It was a Wednesday that Dean finally got what he was waiting for. Unfortunately for him, it was the busiest time in the morning, when everyone was getting their daily dose of caffeine to start their day. Dean was busy working the counter when he stopped in his tracks. Looking slightly awkward among the crowds of people, Mr Blue-eyes took a seat at the back if the cafe. Dean frowned as he noticed one of his regulars, Balthazar take a seat with him.

What was Balthazar doing with him? From the looks of things, both seemed very close to each other, chatting away happily. Well, Balthazar was blabbering away, while the other just seemed to nod and smile in amusement. Occasionally, Balthazar would say something and Mr Blue-eyes would laugh out loud, eyes crinkling and teeth flashing a brilliant white. Dean wasn't the type to get jealous, especially over someone he hardly knew but he couldn't help glaring at their direction, frowning even deeper.

Dean could see one of their baristas, Sarah making her way over to their table, ready to refill their cups. He quickly rushed over to her to stop her.

"Uh, why don't you work the counter, I'll take over for you," Dean told Sarah, practically pushing her towards the register. Sarah had a bewildered expression on her face and from the corner of his eyes, he could see Jo shoot a suspicious look to him. He looked away from them to avoid eye contact, he so didn't want to answer any of their question yet.

Taking a deep breath, Dean made his way over to Balthazar's table, gripping the pot of coffee tightly with his fingers.

Balthazar spotted him walking nearer and he smiled at him in mock surprise.

"Why Dean, I've never seen your ass leave that chair from behind the counter before! Is there any special reason for you to grace me with your presence?" he teased.

Dean rolled his eyes, he really didn't care about Balthazar at all.

"So..." Dean asked. "Would you like a refill?"

He tried to tear his eyes away from those intense blue orbs, really, he did but he simply ended up staring into them. Balthazar pointedly cleared his throat and both Dean and Mr Blue-eyes jumped slightly. Dean looked down in embarrassment and when he looked up, the other man's cheeks were tinted pink.

"No," Balthazar interrupted. " We're leaving soon."

Dean didn't want to admit it but his heart sank in disappointment as the other man reached out for his wallet.

"Hey, I'll take care of that!" Balthazar said, stopping his friend. "A gentleman always pays the bill on a date!"

The morning possibly went from being the best to being the worst for Dean. He tried not to let his smile waver and handed Balthazar the cheque as he gritted his teeth. It was stupid, getting hurt over somebody he only met once before. Of course Mr Blue-eyes was taken, someone that looked as amazing as him couldn't possibly be single. It was so stupid, but it also didn't stop Dean from hating Balthazar slightly.

After paying their bill, both of them stood up and Balthazar made his way to the door. Mr Blue-eyes was about to leave too but Dean reached out to stop him.

"Wait!" he called out. Sure, the guy was Balthazar's date, but it wouldn't hurt to at least know his name, would it?

"Umm, if you're gonna be a regular here, it'd be great if I knew your name."

Dean cringed inwardly. Way to be subtle, he thought sarcastically to himself.

The man smiled at him. "Castiel."

"Oh, awesome name." Dean should really shut up before he embarrassed himself even more.

Castiel chucked softly an looked shyly up at him. "I suppose you want my number too."

Dean's mouth hung open in surprise and Castiel turned red. "I mean, unless you didn't to..." he stuttered.

"No!" Dean blurted out. "I do, I do want your number! But, I thought you and Balthazar..."

Castiel blushed even a deeper. "Oh, I believe Balthazar simply said that to tease you. He's my cousin."

Dean couldn't stop the stupid grin that took over his face. "That's awesome."

Castiel's lips quirked up in an amused smile. "I suppose it is."

They both exchanged numbers and Castiel left with Balthazar, who smirked at him over his shoulders.

"So, did you get his number?" Jo asked him immediately after the two left.

Dean stupidly grinned widely, holding on to the slip of paper as though it was worth a million dollars. "Hell yeah!"

The rest of the day passed by and Dean's cheeks hurt from smiling the whole time. Not once did he stop, not even when he returned home tired only to realize that his neighbor had gotten an even louder stereo.
