Hello, and welcome to my first B99 fic! This is a series I write for my tumblr, .com, so feel fret follow me there. This will be written in first person, with a reader insert name (Y/N, meaning your name). Anyway, this is set in season 3, right after Rosa breaks up with Marcus, and will be sort of an AU from there! Since it will mainly be a tumblr series the chapters won't be very long, I'll rather post more often. So, without further damn-ado, here is chapter 1!

The sounds of the busy Brooklyn street get's shut of as the door closes behind me, and I take a relived breath as I step into the elevator. Even though it's been five years now, moving from my suburban life in upstate, New York, and settling down i Brooklyn have been quite the change, but I'm honestly really enjoying it.

Honestly, if you told me that I would end up as a cop. a legit cop, while I was still at NYU majoring in computer science, I would have laughed it off. But, faith works in strange way I guess, because here I am, I survived the police academy, and had been working at precinct nine-nine in Brooklyn for almost two months.

My train of thoughts is forced to a halt as the elevator stops, and the door open. I step out of it, and walk into the precinct, towards my desk.

It's friday, and early, and the only other employee that's here and I know, is Amy Santiago, a sweet, but a little tight wound, detective. I stop at her desk, and put my coffee cup down on her desk as I start rummaging through my bag to find some papers I know she needs.

"Good morning, Y/N!" She smiles up at me, and i smile back at her as her eyes light up when I hand her the papers. "Thanks!" she says, before she place them neatly next to her keyboard.

"Morning, Amy." I say, as I grab my coffee and look around. "So, no one else shows up early to get work done, huh?" I ask her with a raised eyebrow.

"Oh, sometimes, but I'm usually alone this early." She says seriously, and smile happily at me. "I'm glad you're here early too, maybe we can grab breakfast together from now on!"

Honestly, she seems so exited that I don't have the heart to tell her this is probably a one time thing for me, since I know the internet is faster when the other detectives aren't using it for youtube and other things they're not supposed to, and I'm working on something that needs all the speed I can get.

I just smile at her, and tell her that maybe, and that it sound nice, before excusing myself to go work. Of course she doesn't have anything to say to that, as there's nothing Amy Santiago seems to love more than work.

I sit down at my desk, turn on the computer that belongs to the precinct, as well as I take up my own Macbook Pro, and start booting up all the programs I need to work on my current project. As time passes, I smile and greet the co-workers I know, and soon the internet is moving slowly, and I suddenly have a lot of time to look around while the program works it's magic.

Over by Amy's desk, another detective, Jake Peralta, has shown up and is sitting at his desk, which is placed right across Amy's. Standing next to him is Charles Boyle, a sort strange, but kind and funny guy, and he's talking excitedly to an equally hyped up Jake. Knowing them, they're probably imaging a case to be way more badass than it really is.

Right behind me is the assistant of the precinct Captain, Gina Linetti, tapping away on her iPhone, as the social media godess she is. The Captain, Ray Holt, is sitting in his office, and I smile as I see the little rainbow flag he has on his desk. It feels good to not be the only gay person here.

Across the room I see Sargent Terry Jeffords, who honestly scared the living shit out of me when he interviewed me for the job, as he is HUGE and look rather intimidating, but after no ore than five minutes of talking to him, I realized he's the sweetest guy ever, married with two kids, a minivan and a extreme love for yoghurt.

He's talking to the person I probably get along with the best here, Detective Rosa Diaz. Honestly, it's not as much about getting along, as much as it's about me having the biggest crush on her. She's tall, slim, but strong, with dark, wild curls, and dark eyes, and I was lost from the moment I saw her.

The only problem is that she's not gay.

I was really hopeful the first days here, but after catching up on some gossip, I learned that she had recently broken up with our Captains nephew, a guy named Marcus. So, I'm stuck at dreaming from afar.

But, there are some things that doesn't really makes sense. After my first two weeks at working here, during which I started to hang out with Rosa quite a lot, drinking at Shaw's the bar of choice for cops around here, and just talking about our shared love for horror and slasher movies, the others started making some strange comments.

Like, they keep asking me what I did to get Rosa to actually talk to me and tell me things about her, and when I told them she was the one who asked me to hang out, they seemed surprised. I guess she's usually not the most social person, but honestly, I like hanging out with someone who doesn't need to talk ALL the time.

I've been staring at Rosa for too long, and just as I avert my eyes, I jump as I realize Jake and Charles are now standing on either side of me, trying to figure out what I'm staring at.

"Can I help you?" I ask them, and try to regain my dignity.

Jake grins at me, and Charles looks at my computer screen with horror in his eyes.

"Do you understand any of that?" Charles asks with admiration in his voice as he points to the codes on my screen.

"Well," I start, looking at him with raised eyebrows, "I did go to college majoring in this stuff, so I do understand a fair bit, yes."

He clearly doesn't get my sarcasm, as he just nods slowly, looking impressed. I sigh and turn to Peralta again.

"Seriously, what do you want?" I ask.

"Whoa, bad mood?" he asks, and tilts his head.

I shake my head slowly.

"No, sorry, I was in early working on this and I'm a little tired." I explain and gesture to the computers.

He nods. "Cool, cool, cool, cool…" he trails off, before clapping his hands, and smiling at me. "So, Y/N, are you seeing anyone?" he asks, straight forward.

"No, Peralta, I am not," I start slowly, not sure where he's going with this. "But, you're really not my type, you know, I prefer The V's to the D's, you know?" I say jokingly.

"Hah, V's…" he giggles to himself and I roll my eyes. Such a child.

"We do know you're gay," Charles cuts in, "and we think we know someone who likes you…" he trails off, raising his eyebrows at me.

I shake my head promptly. "No, not happening." I say, and turn back to my screen.

"What, why?" Jake exclaims.

"Because, I don't trust blind dates, i don't want to get mixed up with anyone who has something to do with work, and most of all, I don't trust any of you two to know when anyone likes anyone." I say calmly, while writing in a code on my Macbook.

Both Jake and Charles looks a bit offended, so I sigh, and turn back to them.

"Come on guys, I've only been here for a couple of months, I'm still settling in to work, dating just isn't on my calendar right now."

That, I think, and I'm already into someone. But that's my secret.

Charles nods and puts his hand on my shoulder, and Jake groans and tilts his head backwards dramatically as he walks away. I roll my eyes, and freeze when I see that Rosa is standing over by Gina's desk, and I pray that she didn't hear any of that.

The rest of the day kind of goes by in a blur, and I end up staying late to finish up the coding so I don't have to come early tomorrow too. As I grab my bag and get up from my desk, I realize most of my squad is gone, except Jake, who's talking to Captain Holt, and Terry, who's still writing on something on his computer. I tell him goodbye, and make my way to the elevator again, yawning.

As the elevator reaches the ground floor and the doors open, I almost walk straight into Rosa, who's luckily more awake than me, and manage to catch me by my shoulders and help me regaining my balance.

"Whoa, sorry!" i exclaim, shaking my head, feeling clumsy and awkward.

"No problem." She says simply and offers a tiny smile.

We both stand there for a while, just waiting for the other to say something, and just as I finally get my mouth to work, she says something too.

"Okay, see you tomorrow."

"I like you and I think we should go on a date."

I blink a couple times, the glorious mix of way to few hours of sleep, working late, too much coffee, being so close to my crush and speaking at the same time giving me the reaction time as a sloth.

Then, I realize what she said, and I freeze.

Did she really say that we should… date?

Or am I that tired that I hoped she would so I heard it?

Maybe she didn't say anything at all, and this is all just a part of the simulation theory I stayed up till 2 A.M. reading yesterday when i should be asleep.

"Never mind, that was stupid, just forget it." Rosa says quickly and start to walk away, but thankfully I snap out of it, and grab her arm to stop her.

"NO!" I yell, much louder than I wanted, and she raises her eyebrows and tilts her head a bit.

"No," I say, much calmer this time, "that was not stupid, I'm stupid, and tired, and I want to go on a date." I say quickly, and bite my lip.

"With you." I add lamely.

Another small smile appears on her face, two in five minutes, that must be some sort of record, and she nods.

"Okay, I'll pick you up tomorrow at six, then." She says, and walks into the elevator, leaving me in a mild state of panic, and a wild state of giddy excitement.

This has to be on the top 5 list of strange, and great days of my life.
