Hello readers! It's MikadoTheAirConditioner here with another Durarara AU. This is set in a world where Mikado isn't the leader of the Dollars and Masaomi isn't the leader of the Yellow Scarves. Celty is human and Mikado is Izaya's little brother. Originally, I was going to make this a oneshot, but then I changed my mind.

Chapter One

Izaya didn't really have much when he was growing up. He didn't have video games or a television in his room. He didn't have a pet dog, cat, bird, or snake. What he did have, was an alcoholic father who occasionally got violent, along with an equally alcoholic mother. However, when he was twelve years old, he got something else. He got a little brother. Mikado Orihara was not born into a household with nice parents, but he was born in a household with the most caring older brother that anyone could have asked for. Whenever their father got a little too angry and a little too drunk, Izaya made sure that none of it was directed at Mikado.

Their mother died when Izaya was sixteen and Mikado was four. She had been driving a car after she had been drinking. Their father gradually got worse and worse. When Izaya turned nineteen, he filed for sole custody of Mikado. After looking at their father, who was drunk nearly every second of every day, and after realizing that Izaya was the only family that Mikado had, the judge granted the motion.

Izaya had become an information broker, and he made good money from it. Soon, he and Mikado were living in an apartment together, just the two of them. Izaya was determined to take good care of his baby brother and make sure that no harm would ever come to him.

To say that he was overprotective would be an understatement. He was ridiculously overprotective, to the point where Mikado had to draw the line when he wanted to send a body guard to school when he started going.

Mikado knew that his brother loved him, and he loved his brother, but he was getting a little extreme with his protection measures. Whenever he made friends with someone, Izaya insisted on doing a complete and thorough background check on them, and if Mikado came home with a single scratch on him, Izaya was immediately there with band-aids, gauze, disinfectant spray, or whatever else he had in his giant first aid kit. At one point in school, Mikado had had some issues with some kids picking on him, and Izaya had though it fit to go to the school and personally talk to the kids. Mikado was pretty sure that his brother traumatized all of the children.

Izaya trusted most of Mikado's friends, like Kyohei, Anri, Walker, and Erika, but he had some doubts with Mikado's first friend that he had made, Masaomi. Mikado had met him during his first day of school, where Masaomi had basically declared that he was going to be Mikado's friend. Now, Mikado was very shy, and he hadn't had any other friends before, so he went along with it. Soon, Masaomi and Mikado had become inseparable.

Mikado was so excited to have made a new friend that he had immediately told his older brother about him as soon as he had gotten home. Izaya thought that it was great that his little brother had made a friend, but he had to make the necessary precautions. That night, he researched the Masaomi kid and his family for any suspicious connections with any gangs, suspicious companies, or god forbid, the yakuza. But, he couldn't find any dirt on the kid's family. The next morning, Mikado asked if he could have Masaomi over for the night, and Izaya had said yes.

Now, at first Izaya had kind of liked the kid. He was pretty nice, if not a little silly, and he was a good friend to Mikado. And that's what Izaya thought that they would stay. Friends. But apparently, he misjudged Masaomi because after a couple of years of the two boys being friends, he began to notice some things. Like the way that Masaomi's gaze would sometimes linger on Mikado for a little bit longer than what would be considered normal. And how whenever the other wasn't looking, the two boys would just look at each other with a strange look in their eyes, and if one was caught by the other, they would look away and start blushing. One day, Izaya had went out to buy some take out for the boys since Masaomi had been staying over and he just hadn't felt like cooking that night. When he had gotten back he found the two boys on the couch, snuggled up together and watching a movie. But what had caught his attention was their hands. They were side by side, almost touching, and it looked like they were slowly inching them together. When Izaya announced his presence, the two had jumped away from each other, like they had been caught doing something bad.

Mikado had told Izaya that he was bisexual when he had been fourteen. He had looked a bit nervous, but determined. Izaya, of course, hadn't cared. He would never be able to be upset with his precious baby brother and of course he wouldn't get upset over something like sexuality. But this meant that he had to be extra vigilant when it came to his brother's suitors(who uses the word suitors anymore? Apparently Izaya). And of course, he had to watch out for Masaomi. Lately he had gone through something like a makeover. He had dyed his hair blonde and during the summer he had gotten a tan. And he seemed to talk a lot about girls. Yuki, Ai, Choko, Nashi, etc. It seemed like he was always talking about some cute girl whenever Mikado was around, and the raven adopted a sad look in his eyes whenever it happened.

Izaya didn't understand it. He knew that Masaomi liked Mikado, and vice versa, so he couldn't wrap his head around why Masaomi was always talking about all the different girls he liked.

It puzzled him so much that he decided to talk to someone about it. Which is how he found himself at Shinra's apartment while Mikado was at Masaomi's for the night. He rung the doorbell and soon heard footsteps. The door opened and he was greeted with the sight of a white lab coat and black hair. "Why, it's Izaya!" Shinra exclaimed as soon as he saw the information broker. "What are you doing here?"

"What?" Izaya responded. "Am I not allowed to come visit you and your lovely wife? By the way, where is she?"

"Why do you want to talk to Celty?"

Izaya hesitated a bit before answering. "I need some advice," he admitted with a pained look on his face. Usually it was people that came to him for help.

The look on Shinra's face could be compared to some people who saw an alien invasion descending on the Earth. Disbelieving, wondering, and kind of scared. If Izaya needed help with a problem then it must have been a very bad problem.

If you would have watched the scene from an outsiders perspective, you would have seen an intimidating man in dark jacket standing in front of a man in a lab coat who was standing in the doorway and with his hand on the nob. You also would have seen the intimidating man adopt an impatient look on his face, then you would have seen the man in the lab coat throw himself on the intimidating man.

"I'm so honored," Shinra wailed as he hugged Izaya. "You're coming to me for help with a problem!"

"I wasn't going to ask you for help, you idiot," Izaya grunted as he struggled out of the doctor's embrace and into the apartment. "I was going to ask Celty!" Just then, Celty stepped out of the bathroom, where she had finished dressing after her shower. Summoned to the living room by the commotion, she walked in to see her husband clinging to Izaya and crying. Now, Celty could tell when Shinra was using crocodile tears, which was most of the time, so she wasn't worried about that. However, she was a bit interested why Izaya was here, and without Mikado no less.

She walked over to the two men and wrestled her husband off of the information broker. Do normal people have to do this? she wondered.

After getting everyone calmed down, the three friends went into the kitchen for some tea. As Shinra was making it, Izaya told Celty about the problems with Masaomi and Mikado. After Izaya told her about the problem she quickly went to work typing out some words on her phone.

Could it be possible that Masaomi is trying to make Mikado jealous?

Izaya read the message and looked puzzled. "Why would he do that? It's obviously not working and it's just making Mikado feel bad."

Shinra and Celty looked at each other, knowing that Izaya was a little slow when it came to dealing with human relationships.

"Masaomi wants Mikado to be jealous of those girls that he's talking about," Shinra explained. "He thinks that if he talks about those girls that Mikado will fly into a jealous rage and want Masaomi all to himself, so he'll confess. But Mikado isn't the jealous type. He's more of the type to smile at his friend's happiness and then cry into his pillow because of how sad he is that his crush is in a relationship."

As Izaya sat there, drinking his tea, he thought about that. Masaomi liked Mikado and Mikado liked Masaomi, but they were too shy to tell each other about it. Masaomi was trying to make Mikado jealous, but instead he was just hurting his crush. Izaya couldn't allow his little brother to be unhappy anymore. If they were to shy to actually talk to each other and form a relationship, then big brother Izaya was going to have to do something about it.
