"Izaya! This time, I'm going to kill you for sure!" A roar echoed across the dead-end alley as a blur of blue and white flew by.

Blue pants along with a blue jacket and a white button up shirt underneath. That, along with the blue tie adorning his neck, revealed that he was, still in high school. He had blonde messy hair, judging by the brown roots, probably dyed. His warm caramel eyes twitched with each step he took.

Said man laughed at the empty threat. He had his back against the wall, running his right hand across the peeling paint; he dug into the pocket of his dark black jeans with his other hand.

Under his trademark fur trimmed jacket, he had on a red shirt that clung to his body. The two teens looked about the same age, suggesting that they probably went to the same school.

He took a switch blade out of his pocket and flicked it open with ease, his smirk never leaving his face; he pointed his blade at the other's chest. Under his jet black hair, piercing red eyes stared back at caramel ones.

"That's what you said last time, Shizu-chan. Have you run out of pickup lines?" Izaya teased, taking a cautious step towards the blond.

Suddenly, an ear deafening crash echoed from above the alley. Startled, the soon to be informant quickly looked up, only to see a gaping hole on the side of the building. In a split second decision, the blond, who had tried to hunt him down ever since they met, decided that this was the best opportunity to strike.

Before Izaya could look back, he felt breathless as Shizuo wrapped his hands around his neck. He cursed silently as the blonde's grip intensified in the next moments.

"Do you have any last words before you die, you damned flea?" He smirked, much to Izaya's displease.

"Yeah…you should really make sure your enemy has his hands tied down, you stupid protozoan." He managed to gasp out before impaling his blade into Shizuo's arm.

"F…Fuck…stupid…flea…" He winced at the blood dripping down his uniform. His grip only intensified, making the other choke. He opened his mouth to say something, but Izaya wasn't paying attention; he was too busy gaping at the debris and pieces of splintered wood making its way down from the roof of the building they were standing by.

Izaya groaned as he felt something tickling his face. He tried to get up, but gave up when pain shot up his leg. Slowly opening his eyes, he realized something yellow was blocking his view. Roughly pushing the yellow intruder away, he was shocked to see Shizuo sprawled over him, with his arms wrapped around the informant's body protectively.

'Oh fuck' he thought as the guilt hid him, 'Shizu-chan was trying to protect me.'

Seeing how his enemy was bleeding and unconscious, he suddenly felt pity for him. With the guilt and pity raging in his mind, he managed to stand up and carry the monster to Shinra's apartment. Limping slightly, he slowly made his way to the elevator.

The door opened with a ding.

A masked man with Shinra's brown hair and manner of talking greeted them, "Hello, Shinra's not here, so I'm…Oh my! He's bleeding!"

Izaya snorted, "No shit."

Even though it was Shinra's father, Izaya had no patience for chit chatting.

"Since Shinra and Celty are not here and this dumb ass here is bleeding to death, I suppose it's you who will be taking care of us." He said with a hidden hint of contempt.

"Yes, yes…come in, come in. I am his dad after all; I suppose I can spare some of my amazing talent." He said gleefully. He took out two stretchers, laying them next to each other. "I'll be working on both of you at the same time, since it'll save more time." He explained.

"Yeah, yeah, just make sure that he doesn't die. Only I get to kill him." Izaya shrugged. He helped Shingen put Shizuo on the stretcher and laid himself down on the other one, his eyes closed the moment his head had hit the stretcher and his whole body relaxed. He didn't know what was happening to him, or what was happening to Shizuo, but to be honest, he didn't care.

"Okay…where is this…yeah…what was it again the thing I needed for stop the wound from aching? Ah, yeah…that's it." The doctor said as he fumbled with the placements of his son's medicines.

He hardly ever visited his son, he didn't know where all the equipments were, and he sighed in frustration. It had been a pretty long time since he had operated on someone and he was getting pretty nervous. It wasn't that he doubted his skills, but he wasn't feeling on top of the world that day. Sweat and his constant sighing was beginning to fog up the mask. It was pretty dirty, since he never had the chance to clean it, but he didn't want the polluted air to pollute his lungs, so he just kept on going. After a while, his mask was so fogged up and he couldn't recognize what he was taking into his hands. And sometimes, even if there are many ways to skin a cat, a little mistake can make the result catastrophic.

He sighed one last time as he finally bandaged and disinfected both boys, he turned to take a bath when he heard the door opening. Shinra casually took off his shoes and walked in, setting his stuff from science class on the dining table. The boy didn't seem surprised when he saw his father, since he himself had begged to come, but he was surprised to find his two friends sleeping soundly on the stretchers, and his father's hands covered in blood.

He sighed again as Shinra send him a questioning look. That was enough for Shingen to know he had to explain some things, so he quickly tried to explain what had happened. Shinra nodded knowingly and told him to go away. Then once his father disappeared around the hall way and into the bath, he quickly walked over to the table between the two stretchers and looked over the materials his dad had used.

"WHAT THE HELL?" He shouted as his eyes caught a bottle on the ground. He quickly picked it up peeked inside; there weren't a single drop left. Shinra fell to his knees; he let the plastic bottle fall out of his hands and buried his face against his lap.

"That bottle…was my experimental work of over two years! Why? Its name may be similar to the product we use to stop the pain, but…it clearly has got a symbol warning of danger. What were you trying to do, dad? Do you hate those two that much?" He shouted as tears and snot flowed freely down his comical face.

He wasn't that concerned about his friends, but rather about his work that had gone to waste. He sighed and took a mental to poison his food later.

"Ugh, why are you so damned loud, Shinra? Can't you see I was trying to sleep?" A muffled groan came from one of the stretchers.

"Oh…Izaya…I have some bad news for you...and Shizuo" He said dryly.

"Huh? What's wrong?"

Shinra sighed and dragged his hand down his face in annoyance, "Your souls have been tied together by this experiment I did. My dad mixed it up and..."He cringed as the thought of his stupid dad, "well…you won't be able to stay away from each other. The maximum distance you are allowed to put between each other is two meters. I think, it may even be less."

"WHAT? No…Shinra I don't believe what you are saying. This is a lie, you can't be that cruel." The raven-haired teenager plead, his knuckles white from gripping the side, "Isn't there some way to reverse this shit?"

"Ah...you see," The doctor chuckled nervously, "My dad used it on you guys before I even finished experimenting and testing it, so no. I don't even know the side effects of it!" He moaned in frustration.

Izaya glared at the doctor skeptically, and stood up. "You're just pulling my legs, aren't you?" He smirked as he took as few steps away from Shizuo, who was sound asleep at the time. Not a second later, he felt a harsh tug from his back; he turned around expecting it to be Shinra, but he was surprised to see Shinra crawled up in the corner sulking, and mumbling something about burning his dad's body in the forest.

His eyes twitched in annoyance as he decided to sprint a few more step. A soon as his weight shifted forward, the strong pull made him fly backwards and onto the floor, at the same time, the force pulled Shizuo off the stretcher and came crashing down.

"Ugh...what the hell?" Shizuo mumbled as the impact woke him.

Shinra had come to check up on them when he heard a crash, he looked at Shizuo, and he could tell it was a bad idea to wake him from his sleep. He didn't even want to think about the reactions when he found out about the curse.

Izaya looked at Shinra; there was panic in his eyes.

"Why'd you push me off my bed, flea?" Shizuo accused.

"Hehehe..." Shinra scratched his head nervously, "Well, about that...this is not your bed," He looked at Izaya for help, and Izaya quickly said, "We have a problem."
