So I decided to start another fanfiction that's not just a one-shot and I decided to do something less angsty because I defiantly need a break from that (I'll still do some angsty stories, just not in this story this will be a more hurt / comfort and lots a humor and fluff to go along with it.) anyways I have not edited this or anything so if you guys see any grammar mistakes / mess ups just let me know in the comments and I'll be sure to fix it. Anyways enjoy!(:

The first time they met, they were five years old starting their first day of Kindergarten, the teacher had sat the two together because it had been the only seats left open.

Shizuo was shy, scared even for his first day of school and he didn't want to leave his mother either but his mother had reassured him that it would be okay and that he'd soon learn to love school. So he decided to stop crying and give it a chance, because after all he didn't want to upset his mother.

Izaya was the complete opposite, he couldn't wait to start his first day at school because he was excited to see how the other kids were and to make friends obviously. Izaya was already a little shit, he loved causing trouble and seeing how others reacted when trouble was made. Happily he said bye to his mother and skipped into class ready for the school year to begin.

Little did Izaya know he was about to encounter one of the most interesting humans — no not human but monster.

Sitting down in the sit He was assigned to, he looked over to the other who had stuffy red eyes from crying and he was clenching to his backpack. "Hi I'm Orihara Izaya, nice to meet you!" Izaya said sticking out his hand for the other to shake.

Shizuo just stared at Izaya, hiding behind his backpack. "Heiwajima Shizuo." He sniffled just wanting to go back home to his mom, it was the first time he had ever been without her and he was scared and overwhelmed all in one.

"Why've you been crying hmm?"

"I-I haven't…. I'm a big boy and big boys don't cry…" Shizuo said defensively.

"Your eyes say different… They say you've been crying and the way you're hugging you backpack like a teddy bear says that you're defiantly not a big boy." Giggled Izaya.

"Am so!"

"Nuh-uh! Who told you that, your mommy? If so, she's a liar!" He teased already finding joy in messing with the other.

"Don't call her that! She is not!" Shizuo yelled not liking this kid already, this kid already made him want to smash his head in just for speaking ill of his mother.

"My mommy would never lie!" He shouted only for them to be interrupted by the teacher telling them to calm down because class was about to start.

"You're a mama's boy!" Izaya giggled only to make the other even more pissed off.

By the end of their first day at school, Shizuo already knew he didn't like Izaya. First because he insulted his mother, second he got him in trouble with the teacher, third he had stolen his favorite crayon as a joke and wouldn't give it back until the teacher had forced him, thirdly he had made his spill his milk all down his new outfit during lunch.

Izaya was a pest, something Shizuo defiantly could live without and when he got home he told his mother all about the stupid boy he had met at school today.

His mother just laughed it off and told her son that some people don't really know how to make friends and find it easier to tease as a way of saying they like you.

Shizuo just huffed and went up to his room to play in his room until dinner was ready, not ready to go back to school because he didn't want to see Izaya again.

The next day Shizuo had met a couple of friends by the name of Shinra and Kadota, they were nice, ate lunch with him and even played on the playground with him. The only problem was that they were friends with the jerk from yesterday, Shizuo tried to ignore that fault though because he really wanted friends because well, he had never had any friends before. So for the sake of keeping his friends he tried to get along with the other boy, but Izaya wasn't having any of that he liked causing to much trouble to let there be any peace.

He did anything he could to irk the others nerves, call him names, pick fights, mess with his lunch or school supplies, and even pranks that he had learned from his dad.

It had the whole class laughing at how Shizuo and Izaya bickered back and forth, the teacher had tried everything to get the two to get along but never actually succeeded because Izaya wouldn't let her, no way was she taking away his new favorite toy.

Shinra tried to help keep the peace between the two but he failed also, Kadota didn't care as long as the two didn't take it to far — which with them being only five years old, they never really did.

By the time they were in first grade, Shizuo was hoping he wouldn't be in the same class as Izaya but of course luck was never on his side, he was in the same class and even sitting beside him again. But good thing was, so was his friends so maybe this year would be better.

Izaya was more annoying than usual this year though, he had decided to start calling him by the nickname "Shizu-Chan" and it pissed Shizuo off more than anything. Every time Izaya used the stupid nickname, Shizuo tried his hardest not to bash the boys head in, because why couldn't Izaya just leave him alone? Better yet jump off a cliff somewhere and die?

"You know… my mom always tells me when someone picks on you, it means they like you!" Shizuo finally said one day at lunch, because Izaya had decided to switch his lunch with cat-litter.

"And you listen to everything your mama tells you?" Izaya commented back.

"As a matter a fact, I do and I think you secretly like me!" The first grader said, not really knowing what "like" really was, he was just saying what his mother told him.

"I don't like you… hate is more like it!" Izaya said getting closer to the other.

Shizuo's lip quivered just the slightest, he had never had anybody hate him before, he tried his best to be lovable and nice to everyone he meets and yet Izaya hated him? But why? What had he done wrong? If anything he should be the one hating Izaya, which he did — well he thought he did anyways.

"Well good because I hate you to! Why can't you just die already!" Shizuo huffed out, throwing down the bento that was still filled with cat-litter and stomped off from Izaya and his friends.

"Why'd you go and say that Izaya?" Shinra asked.

"Yeah… That wasn't very nice you know?" Kadota scolded making Izaya roll his eyes and stomp off on the other direction as well.

"What are we going to do with those two?" Shinra sighed.

"I don't know…" Kadota replied as he finished up his lunch with Shinra before heading back to class only to find Shizuo and Izaya missing.

"They're in big trouble if they end up skipping class…" Shinra said worryingly for his two friends.

Meanwhile Shizuo had found himself leaving the school because he just didn't feel like being there anymore, he was actually going to walk home because he didn't feel like socializing or even being outside today, he just wanted to be under his warm blankets watching television and not have to worry about the damn flea… Flea… yeah, that's what he was a flea… he'd have to use that more.

Sighing Shizuo was so close to his house only to realize he was being followed, turning around he was met with the one person he didn't want to see right now.

"So you're just going to skip school because I hurt your feelings?" Izaya taunted, he wanted a reaction out of Shizuo, a real reaction, one that showed him he was willing to fight back and not this wussy mamas boy that he was seeing.

"I'm not in the mood for you flea…" Shizuo grunted out. "I'm never in the mood for you really, I just wish you would learn to leave me alone."

"And what if I refuse to, hmm?"

"Then I don't know… what do you want from me?"

"I want you to fight back and stop listening to everything your mother tells you!" He said but when Shizuo just turned around and begun walking away, well that upset Izaya because he didn't like being ignored. He ran up behind the other and pushed him down toward the ground, "Don't walk away from me!" He yelled.

Shizuo had tears forming in his eyes and it wasn't your normal sadness ones, it was out of anger. He tried so hard being nice, he tried so hard for everyone to like him and yet Izaya just kept on and he didn't know how to stop it.

Shizuo's knees were bloody from scrapping against the asphalt, his hands were bleeding slightly as well he turned back to Izaya mind going blank from anger as he sent a punch across the others face. "I SAID…. LEAVE ME ALONE!" He screamed to the top of his lungs watching as Izaya flew to the ground. Only then Shizuo realized what he had truly done, "Izaya…. I-I'm sorry!" He yelled before taking off and sprinting in the other direction and not stopping till he got to his house.

Izaya laid there in shock yet amazement as he watched the other run away, his eyes just widening in aspiration because he had finally gotten his way, he had gotten the other to fight back, he had gotten his favorite human to fight. Rubbing his cheek as he stood up, he begun skipping back to his house because in all honest he didn't want to go back to class either; not without Shizu-Chan anyways.

From that day on, Izaya and Shizuo began to fight a whole lot more, Izaya usually being the one that starts it because he loved getting a reaction out of Shizuo more than anything.

When they were nine years old Shizuo had began to get strong, which led him in the hospital every time he went to pick up objects that were way to heavy for someone so little, but by the time they were ten he begun to get the hang of it and it was becoming easier to pick up heavy objects — even though he still ended up in the hospital most the time because of broken bones and injuries when he decides to pick up something beyond his normal heavy.

"Wow Shizu-Chan has become a monster!" Izaya would always giggle out during their fights. "He's not human anymore, he's a big monster!" Taunted the younger.

Which only pissed off Shizuo even more and it'd give him more motivation to kill him,

"SHIZUO HEIWAJIMA YOU PUT THAT CHAIR DOWN THIS INSTANT!" His teacher yelled at the blonde who had a chair high in the air ready to bash Izaya Orihara's head in.

"And you Orihara, put that tongue back in your mouth!" Came another scolding at the now two ten year olds who were in yet another fight. "I won't hesitate to separate you two if you guys don't learn to get along!"

"Now apologize to one another and then take your seats, do you understand me?" Mrs. Yomo said but the two little ones just glared at each other not saying a word or even apologizing before the just took their seats.

"Stupid protozoan…"

"Damn flea…" the two mumbled simultaneously.

It was after class when Shizuo and Shinra all met up for lunch and Izaya stayed behind to work on his project he needed to finish before next class.

"Why can't you and Izaya learn to get along? You guys are always interrupting class to fight and honestly it's getting out of hand!" Shinra said scolding him as well.

"It's not my fault, it's that damn fleas fault for always starting it." Grumbled Shizuo as he took a bite of his food.

"I don't understand you two."

"What's there to understand? We hate each other, that's all there is to understand."

"Yeah but still, you two need to chill it on the fights." Shinra added as he ate his own food.

By the time lunch was over, Shinra had wondered why Izaya hadn't shown up. Working on that project couldn't have taken that long, he just had a few things to add to it before being done. Shrugging it off he headed back to class with Shizuo, only to see a big crowd surrounded by Izaya's desk and there was four boys cornering Izaya in.

"Little fucker, you and that friend of yours is always disturbing the class. Don't you realize that some people are actually here to learn?" Who of the boys pushed Izaya making him trip over his feet — and anybody who knew Izaya knew he wasn't a weakling, he would draw blood if he had too and that was his intention to, seeing as he had a pencil in his hand that was freshly sharpened at the time and he was about to gab the thing in any place he could reach first.

Shizuo had been standing a few feet away watched as these boys harassed Izaya but not once did he see the pencil in the others hand, all he could see after the push was red because he was beyond pissed. Izaya was his, his to mess with, and to fight. Not some little punk ass kid who decides he wants to get tough.

Out of blind furry Shizuo picked up the nearest thing to him which happened to be the teachers desk, "Hey you little fuckers! What makes you think you can touch what's mine?" Huffed Shizuo before Izaya was able to use the pencil as defense.

"You got to the count of three to have your asses out of this classroom or I won't hesitate to kill you!" He warned.

"One…" He begun as he stepped forward.

"Two…" He watched as the students scrambled to get out but Shizuo had quickly made it to three as they were halfway to the door, he had launched the desk into the air and it smacked all four boys down to the ground leaving the whole class speechless and wondering if they were still alive —thankfully they were.

Shizuo then snatched Izaya up by the arm to pull him close to him in a protective manner, "I could have handled myself, I don't need you to fight for me." Izaya huffed and brushed off his pants and shirt.

"Yeah then why didn't you?"

"Because you didn't give me a chance…"

"Well next time I won't save your ass, no matter what!" Shizuo yelled throwing his hands up in frustration.

"Good because I don't want your help nor do I need it!" Izaya added the two boys butted heads. "And as for you saying I'm yours…. I'm no ones!"

"Guys… Guys… settle down, we don't need another fight!" Shinra interrupted before Shizuo could answer back.

"Shut up!" Both Shizuo and Izaya yelled at the other simultaneously making Shinra shrink in embarrassment.

The teacher soon had walked in and saw the scene, "what is going on in here?" She inquired only to look at the two main troublemakers. "You two, principals office now!"

"But it's not my fault this time!" Shizuo said. "I was helping the flea here and instead of him being grateful, he's being a pain in the ass."

"Language Heiwajima!"

"Yeah language you stupid protozoan!" Izaya giggles in a teasing manner.

"Fuck you flea!"

"Nuh-uh Shizu-Chan… didn't sensei just say for you to watch your language?" Izaya hummed.

The teachers eyebrow twitched, "go… now… the both of you!" She said fed up with the two of them.

Izaya happily skipped out of the class and Shizuo followed after grumbling under his breath. "It's your fault we're in trouble." He huffed as he followed behind Izaya.

After school Izaya and Shizuo had met up with Shinra and Kadota, "Dotachin!" Izaya beamed and went over to wrap his arms around him in a hug.

"Hey guys! Heard you two got in trouble again today." He said as Izaya pulled back.

"Yeah, all because of mean Shizu-Chan!" Izaya pouted in a innocent tone.

"Me?! I was helping your ass you damned flea!"

"My my Shizu-Chan, for someone so little you have such a foul mouth!" Izaya teased.

"Little? I'm older and bigger then you? You little rat!"

"Hmm, are you?"

"Yeah I am, see!" Shizuo said making hand movement against both of their heads to show the height difference.

"If you say so…"

"Look! I'm showing you, look at the height difference! I'm defiantly bigger."

"Okay I totally believe you!"

Shizuo growled as Izaya wasn't looking at his hand, "Izaya's messing with you… Just ignore him, less fights that way." Shinra said trying to prevent another fight that day.

"I am right though…" Shizuo huffed only to say goodbye to Kadota as they neared his house, then Shinra was next to leave.

It was just him and Izaya now and that was what Shizuo was dreading the most because he didn't want to be left alone with the younger when Shinra wasn't there to help stop the two from doing something stupid.

They walked for about two minutes in silence before Izaya turned around to speak, "What did you mean when you told those guys I was yours?" Izaya inquired.

"I don't know… why are you asking me flea?" He asked not really knowing why he said it or even why he got protective over the younger like he had.

Izaya bit his lip and shrugged. "Just wondering." He said before he ended up at his house, "See you later Shizu-Chan!" Called Izaya over his shoulder as he ran into the house.

January 28th was Shizuo's birthday and he had invited the whole class to his birthday party, even Izaya because his mother had forced him because she told him it wasn't nice for him to exclude just one person and despite the fact him not wanting Izaya there he decided he wasn't going to let that ruin his mood. So he excitedly helped his mother with the decorations, the cake, and even setting out the rest of the food. He was excited for one of two reasons, one it was his birthday (obviously) and second he was hoping to make some more friends.

But at the last minute Kadota told him he couldn't come because he was sick and Shinra was heading out of town for a family vacation, but Shizuo still wasn't going to let that ruin his day.

So he decided to wait on the porch for his guest to arrive, because the party starts at 2pm and he wanted everybody to know they had gotten the right house.

But 2:30 had rolled around and nobody had showed up, Shizuo was trying his best to tell himself that they were just late but deep down he knew they were coming. Why would they? They were all probably scared of him, he knew that. He just wished that at least one person would have shown, around 2:50 Shizuo stood up on the porch with a sigh about to head about in because he could feel his parents and brother staring at the back of his head in sympathy and he didn't want their pity.

"Shizu-Chan!" Can a loud yell behind him stopping him in his tracks, of course the one fucking person to show had to be the damned flea.

When he turned around he was met with Izaya holding a medium size cake and that big ass smile that never seemed to fade on his face, "What do you want?" He growled out.

"Now now Shizu-Chan, is that anyway to speak to your guest?" Giggled Izaya as he skipped up to the other, holding the cake close. "And to think I stayed up all night baking this cake for you."

"Why would you do that?" He asked trying to find the joke in this, but Izaya never swayed he just kept that big smile on him as he showed Shizuo the cake he baked.

"Because it's your birthday… duh!" Izaya said watching Shizuo study the cake as if it were going to explode. "Plus I really wanted to do that!" He said before taking the cake and smashing it in Shizuo's face, watching as it dropped from the others face and down to the floor. "Happy Birthday!"

"IZAYAAAAA!" Shizuo screamed at the boy while he watched him laugh hysterically as he began to run away but Shizuo wasn't in the mood to chase or even fight, he felt like crying more than anything. His birthday was ruined, nobody showed up —besides the bastard flea — and now he had cake all over him and his good clothes. Sniffling Shizuo begun to tear up a little, forcing himself as much as he could not to cry as he bent down to clean up the cake.

His mother had come rushing out to help and about mid way of cleaning, Shizuo had stumbled upon a small box that had been inside the cake it was wrapped quite nicely. Shizuo had hesitantly unwrapped the box, suspecting it to be another trick from Izaya but when he opened it he saw a colorful handmade bead bracelet with the lettering 'Shizu-Chan' on it.

Shizuo didn't know how to feel at first, he felt angry because why couldn't the flea just have handed it to him like a normal person but also he felt something else he couldn't put his finger on but pushing those thoughts aside he had slipped the bracelet on and smiled.

After he had helped his mother clean the cake up, he had headed upside to clean himself up as well and he couldn't stop admiring the little gift Izaya had given him.

If you guys enjoyed feel free to R&R because I love your guys feedback, anyways I shall update soon! Till next time!(:
