Hey guys, this is my first fanfic (online) so please, NO FLAMES! This is also rated M for language and sexual content (later chapters). Also a yaoi between Shizuo and Izaya. So if you don't like, don't read. Also, I don't own Durarara. If I did own Durarara, the story would be focused on Shizuo and Izaya. And maybe a little Celty.

Chapter 1: Nice to meet you!

"IIIIIIIIIIIIIIIIIIIIIIZZZZZZZZAAAAAAAYYYYAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA-KKUUUUUUUUUUUUUUUUU UUNNNNNNNN!" Shizuo shouted, carrying his famous weapon: a street sign. Izaya was walking through the street when Shizuo happened to catch sight of his face, and immediately lost his temper.

"Oh, Shizu-chan*! How nice of you to come over and say hi to me!" Izaya smirked. He loved it when Shizuo lost his temper. It just made Ikebukuro more…. exciting. "Shizu-chan, I'm over here!" Izaya taunted. He dodged almost every one of Shizuo's attacks, except that last one, where Shizuo got him in the stomach. Izaya started laughing and coughing at the same time, which got Shizuo even angrier.

"This time," Shizuo said darkly, "I'll really KILL YOU!" Shizuo screamed. Izaya threw his knives, grazing Shizuo when he ran. People started gathering around, texting their friends and looking at the two men fighting.

"Oh my!"

"He they go again…."

"Oh my god!"

Shizuo looked over at them, losing a little bit of his focus on the fight. "THE HELL YOU LOOKIN' AT?!" Shizuo screamed again. Everybody ran. "Now, back to the fight…." Shizuo turned back to where Izaya was, only to find out that Izaya was gone. "Dammit! Damn that flea, damn my temper, damn my strength, dammit, dammit, dammit…." Shizuo went on as he walked back to whatever he was doing. He can't believe that he let that flea escape.

Izaya laughed as he skipped home. "That sure was fun! But… now I'm bored again." Izaya stopped smiling. He sighed. "Maybe I should have stayed to keep fighting him. Then again, I might've died." Izaya chuckled at his own rambling. He entered his key into his apartment door and went inside. Grabbing a bag of potato chips, he sat by his window and looked outside. A couple seemed to be talking about something.

"Sigh…. I could care less." Izaya turned back around to turn on his TV. Then he heard yelling. He looked back outside. The girl yelled something out at the boy, then the boy retorted. The girl pushed the boy, and then ran. The boy kicks the wall. "Haa… still not good enough." Izaya went to his computer to see if he got any kind of message to get any information or any kind of story from anybody. Nothing. Izaya flopped on his couch.

"Shit, why'd I even get this stupid strength? Everybody's scared to talk to me except Simon, Mairu, Kururi, Celty, Izaya-kun, Tom, a few more… okay, I have friends. But Izaya-kun is an enemy!" Shizuo shouted to his brother, Kasuka.

"Well, if you'd be nicer and less violent, then you wouldn't be in this mess." Kasuka said simply, "Plus, you use the honorific '-kun*' with Izaya and only Izaya. Doesn't that mean that he's your frien-"

"Don't even think about finishing that sentence! I use –kun because he's not my friend!" Shizuo shouted.

"Fine, fine. I was just teasing. Hey, aren't you supposed to be moving out soon? I'm going to miss you~!" Kasuka teased.

"I'm 24, dammit! I can live on my own. If you think I'm a kid, then you're a freakin' retard." Shizuo shouted out.

Shizuo walked up to the real-estate agent. "Shizuo Heiwajima, 24, blonde." Shizuo wanted to move out soon to get more space for himself. Or if he gets a girlfriend. Not that he wants one right now.

"Oh, Mr. Heiwajima! Yes, you're on the list for the Ikebukuro-Estates apartment! I will escort you there." The nice woman said. She knew Shizuo's reputation, so she tried not to piss him off.

The ride there was pretty decent, since the day passed by and it was already evening. He rode in the backseat of the taxi, listening to the lady talk about the apartment, showing him pictures of the apartment, and talking about "how nice the neighbors are". He hoped that they take loads off of people's backs, because Shizuo swore that he was getting grey hair through the dye.

"Here we are~!" The agent sang. Okay. She's a little too happy. Like the annoying doctors that come in the room all happy, leave the room, then come back with the needles and more doctors. Your room is the last one to the right. Number 334, straight down the hall to your right. Also, at least let me do you the favor of introducing you to your new neighbor in room 332." The lady cheered. Okay, she's really annoying. Shizuo thought to himself. The lady handed Shizuo the key to his room.

The lady knocked on the door. "Mr. Orihara! Come out and meet your new neighbor! He has sort of a temper, but I'm sure you'll get used to him!" The lady shouted. Orihara? Izaya Orihara? ORIHARA?! Shizuo thought.

"Yeah, yeah, yeah. I'm coming in just a moment!" A voice yelled. The voice. That voice. Oh Shit. Shizuo thought. The door opened revealing a lean body and tired eyes. "Yes, Mrs. Yamaha? I didn't think anybody else was moving here." Izaya opened his eyes, only for them to widen. Shizuo's eyes did the same. Izaya smirked.

"Why Shizuo! I just talked with you today! I'm so happy to have a new roommate!" Izaya teased.

"So, this guy is going to live next to me…?" Shizuo said as camly as he could.

"Yes, he is! Aren't you happy?" Mrs. Yamaha asked. A vein popped up on Shizuo's forehead. Happy doctor with needles.

"IIIIIIIIIZZAAAAAAAAAYYYYYYYYYYYYYAAAAAAA-KKUUUUUU UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUNN NNNNNNNNNNNNNNNNNNN!"

All hell broke loose.

Hello, my lovelies! I will give you chapters every week, or at least try to. And I also love reviews. And chocolate. Next time, will Izaya and Shizuo work this out? This will be a spark between them that has never happened before… heheheh…

*-chan is a Japanese honorific for a young girl. –kun is a Japanese honorific for a male friend or acquaintance. Shizuo uses –kun because, supposedly, with all of his other friends, he doesn't use honorifics. Izaya uses –chan to get on Shizuo's nerves.
