Izaya and Psyche are twins. However, a terrible bout of sickness when they were little has left Psyche with a weak heart. Worried by the fact that another round of sickness or too much excitement could kill Psyche he was kept home his whole life while Izaya went out and experienced the world. Psyche has never considered venturing outside at all… that is until one night his brother doesn't come home. High school era Psyche/Shizuo, Izaya/Shizuo, and a little hinted Psyche/Izaya. Not a Tsugaru fic.

Psyche sniffled into his pillow, his faded red eyes fixed on the door. He longed to reach for his headphones and block out the creaks and groans of the house, but if he did he might miss the sound of Izaya coming home. Faintly, Psyche could hear the sound of his little sisters soft breathing as they slumbered peacefully next door. He envied them. However, he had never been able to sleep well without his twin beside him. It had always seemed a natural thing to have close physical contact with Izaya, but he got the impression that brothers didn't usually sleep together in the outside world. For instance last time his parents had even been home they'd given them a disgusted look when they'd wandered in and found the two of them in bed together one morning.

"The two of you are too old to be sharing a bed." Sniffed their mother.

"Oh but mother dearest, that's not all we share, ne Psyche?" Izaya had teased eyes glittering mischievously as he draped himself over his twin. Psyche had been confused, clearly he didn't understand what his brother was hinting at judging by his parents horrified looks, but they did share most of their things with each other so he hesitantly agreed. After they'd scampered into Izaya's room down the hall(which was really just there to hold all the extra stuff Izaya had gathered and sometimes where Izaya stayed when he was sick)his brother had leaned up against the door and guffawed.

"Did you see their faces?" he had said with glee.

"Yes… but why were they looking at us like that?" asked Psyche hesitantly.

"Hmm? Ah, because the outside world thinks that anytime two people share a bed together then they must be doing indecent things when no one is around~" Izaya had practically giggled.

"Well that's silly." Psyche had said joining in his brother's laughter. He wasn't sure what "indecent things" were supposed to be, but he and Izaya never did anything but sleep and chat in bed so that was still an incorrect assumption. After that they had spent a while joking about how odd humans could be.

Now, Psyche shifted restlessly in the bed, distinctly aware of the cold space next to him that Izaya usually occupied. The school had called again and left a message reporting that Izaya had been absent from school all day. Since his brother hadn't been home either, and he hadn't called like he usually did if he was going to be out late, and he still wasn't back yet… He knew he was probably over reacting with all his quite fretting. Izaya would tease him for days if he knew, but the outside world seemed like such an intimidating place full of sickness and frightening people.

There was a knock on the front door.

Psyche didn't think he had ever moved so fast. By the time he realized that Izaya wouldn't have bothered with knocking Psyche had already started to open the door. Cautiously he peered outside.

"Psy~che~! Long time no sushi!" Simon greeted him grinning.

"Hello Simon," said Psyche smiling and bowing shyly, Simon was one of the few people he had met from the "outside"… mostly due to the fact that he delivered otoutoro most any time of the day or night.

"Is I~Za~Ya here, hmm?" asked Simon holding up a sushi box.

"Oh, did he order that?" asked Psyche smiling feeling a sense of relief; if his brother had ordered himself otoutoro then he must be coming home soon.

"Hmm! Yes, but I~Za~Ya did not come for it in afternoon. No sushi no good! Yes sushi, no more fights with Shi~Zu~O." hummed Simon counting the money that Psyche had handed to him.

"I- What?!" Psyche squeaked his heart hammering, "Ni-san was in a fight?"

"It's no good! You tell him to eat more sushi and not destroy so much." Said Simon nodding to himself.

"I- I will." Said Psyche hesitantly closing the door. He clutched the sushi box to his chest and slid down the door. Something was very wrong. Izaya would never just forget his otootoro. It was already midnight and he knew his bother didn't have any close friends that he would just stay the night with. He must be in trouble.

Psyche got up with determination and grabbed Izaya's extra coat. The outside was a dangerous and scary place that he hadn't ventured into since he was very small, but if Izaya was in trouble there was no way he was just sitting at home. If Izaya couldn't come home then Psyche would just have to bring him home himself. Taking a shaky breath, Psyche stepped out the door.

Izaya hummed happily as he walked down the street with his hands in his pockets. He had spent the morning pissing off Shizuo and having him chase him all around the city instead of school. Snickering, Izaya remembered the look of the protozoan's face when he realized that he had missed almost the entire day of school chasing him. Of course then he tried to smash him with a near by car but whatever. Totally worth it… or it would have been if he hadn't made Izaya late for his meeting with Shiki. He didn't even get to pick up his ototoro! Izaya pouted at the thought. That blond idiot, he should have cut him up a little more. Shiki had kept him extra late because of his tardiness. Still, watching the humans in the Yukusa was always fascinating so he supposed he didn't mind that much.

Absently he turned his phone back on and was unsurprised by the torrent of messages that assaulted him. They were probably all from Psyche. Izaya grinned to himself. Psyche was one of his favorite humans, his lack of contact with the outside world always caused him to have the most amusing reactions to things. No doubt he had fretted himself into quite a state by now over the fact that Izaya had purposefully been ignoring his calls and staying out so late. He was sure to be clingy and tearfully when he finally returned. Izaya grinned at the thought and hurried home with an extra bounce in his step.

I have a vague idea of where I am going with this story, but it's still and the making and unfortunately I can never predict if I am going to stick with a story or when I am going to drop it... hopefully I shall not drop this one. I have never used FanFiction before so I am still learning. I am also not sure what the final rating of this will be. It could very easily go either way. It'll depend on my mood.
