"I...I don't know why I hate you."

Shizuo whispered, barely audible, then turned himself away, now trying hard to remember back to that day. He had seen the teenage boy in his short jacket and red shirt sitting with Shinra, an annoying smile on his face. Shinra was going to introduce them to each other. But that smile...something about it irritated Shizuo so much, and to top it off, Izaya was acting all high and mighty by his posture. With Shizuo's already aggressive nature, it didn't help when he saw such a person before him. He couldn't help but throw a punch at that boy, only to miss, thus, starting their continuous cycle of cat and mouse.

He turned himself around to face the smaller man, his angry expression having softened to something else...something almost...unexplainable. He looked like he was off in a distant world. His eyes were clouded with confusion, yet something more. Although it wouldn't be obvious to just anyone other than Izaya, there was maybe, just maybe, hints of regret in the blonde's eyes. The informant started to walk closer, looking up at the bodyguard with concern and curiosity.

The smaller male gently put a hand on the others arm, searching his face for any sign of emerging rage. There was none.

High School

"Hey Shizuo, did you bring your lunch today?" A spike-haired brunette with glasses smiled smugly at his friend as he removed his lunch box from his bag.

"Nah. I was going to get something in the cafeteria." Shizuo shrugged, then he watched Shinra blushing while opening his lunch. "Did Celty make that for you?"

"Why, y-yes she did! She makes the most amazing meals." He held the box close to his chest with a dazed smile, only to set the box down and clear his throat, returning to a nervous grin towards the blonde. "Well um, you should go get your lunch now so we can have enough time to eat." He then proceeded to stare at his lunch.

"Snap out of it, Shinra." The brunette didn't look up. "Oi, Shinra!" He bolted his head upright, looking questionably at the blonde. "There you go. I don't need you to be in a daze." Shizuo smirked and then walked out of the classroom, Shinra defying his orders anyway and going back to his daydreams.

Walking down the hallway, another pair of eyes was watching as Shizuo left in the opposite direction. After Shizuo was out of sight, the crimson eyes of the young male blinked as he grinned widely and skipped into the classroom.

"Hello Shinra!" He sat on the desk in front of the surprised boy and put his hand up in greeting.

"O-oh, hey Izaya." Shinra put his lunch in his desk for later and forced a normal smile to hide his previous flustered face. "Where is your lunch? Aren't you going to eat?"

"Yeah later I will." He shrugged. "So Shinra…who was that who walked out of the room a few minutes ago?"

Shinra widened his eyes in a realization. Shizuo and Izaya seemed like they would make good friends! Shizuo didn't really have many friends aside from himself and Kadota, and Izaya seemed like he would get along with the young blonde. Shizuo was stern and Izaya was a bit…well, not exactly on the sane side (according to Shinra). But they would make good friends because Shizuo would, perhaps, keep Izaya under control, and Izaya would be someone else in Shizuo's life that wouldn't be afraid of his super strength, based on the fact that nothing really scared Izaya.

All in all, they would balance each other out.

Izaya waved a hand in front of the other boy, who was deep in thought. "Shinraaaaa? Helloooo?" The future doctor flinched, and then straightened his glasses.
"R-right." He stood up to stretch. "That was Shizuo Heiwajima. He's a good friend of mine." Shinra folded his arms and nodded. "You wanna meet him?"

A surprisingly sly grin spread across the other's face as he stared at Shinra. "Sure. Why not? He seems like an interesting person…" He looked past Shinra out the window. Shizuo was down there, speaking with some people. The brunette's face lit up. "Let's go now Shinra!" Izaya grabbed the other's arm and pulled him out of the classroom, and down the stairs.

Anxious are we? Shinra beamed as he was dragged down the staircase and out the doorway.

Little did they know that Shizuo was about to get himself into a situation he would later regret...

It had happened.

It was to be expected from a monster like him, but it was bound to happen sooner or later.

Shizuo took one final pulse to the ground with the end of the street sign, and those around him fell to the ground, unconscious.

His breathing becoming steady again, he flinched at the sudden intrusion of his dying anger.

Clapping.

Who would applaud what he had just done?

Turning his head slowly to look behind himself, he saw him.
That annoying grin.
The extremely ridiculous feeling Shizuo got when he looked at him.
That disgusting look of enjoyment plastered upon his face.

To narrow it down into simple words...He pissed him off.

Shinra was slightly shocked by what had happened, but he couldn't say that he wasn't surprised, knowing Shizuo. He wasn't too sure when it would be best to say anything, but with Izaya's actions and Shizuo appearing to have calmed himself down, he decided that it was now or never.

"This is Izaya Orihara..." He began with sudden confidence and continued to ramble on about how Izaya was not always that nice of a guy, and it was maybe something that he should have kept to himself. But Izaya took it as a sort of joke and shook it off, responding with ease to redeem himself and somehow managed to keep his cool.

"You piss me off." The words were said clearly as the blonde turned his head away, obviously wanting to be left alone.

The smile on Izaya's face grew even wider, as nodded to himself and decided to challenge just how far he could go with the other teen...

Within the next few hours, Shizuo was chasing Izaya down the streets of Ikebukuro.

"IIIIIIZAAAAAAYAAAAAA-KUUUUUUUUN!"
