Hey guys :) This idea has been on my mind for a while now and I finally started writing it, yeyy :D Here's what's gonna go down in this story:
Blaine volunteers to take part in an experiment which wants to prove that love is based on DNA. What he didn't expect though was to be partnered with three other guys in the process. He's straight after all. Isn't he? Enjoy!

Chemistry

Ch.1 – Coming to meet you

„So... you're really going through with this, huh Blaine?"

The curly haired boy stopped packing his suitcase to turn around and roll his eyes at his mother for what felt like the hundredth time that day.

"Yes, mom. We already talked about this. I know what I'm doing."

"Wouldn't bet on it", the woman leaning in the doorway mumbled under her breath before sighing loudly. "I just... I don't have a good feeling about this. Maybe you should cancel it, Blaine. They can't force you into a project like that after all, can they?"

He turned away, bending down to get six pairs of socks from the bottom of his dresser.

"Can they, Blaine?" The worry lacing his mother's voice also shone clearly in her eyes as she watched her son rummage through his various drawers, throwing the things he'd probably need for the next few months in the rough direction of his bed.

"Mom, I'm going there because I want to", Blaine finally answered softly, sounding convincing enough to calm his mother instantly. He made his way into the bathroom to get his toiletries, sidestepping the stuff that had somehow landed in a heap on the floor instead of in his suitcase, and smiled reassuringly at his mom. "Don't worry about it, okay?"

She sighed heavily again. "I know, I know. Every baby bird has to leave the nest at some point." He couldn't help but chuckle quietly at the cheesy comparison. "But you're still so young, Blaine, I..." Her eyes shone with sadness as she shook her head and returned his smile shakily after a few moments of collecting herself. "I'm being stupid, right? Well, I guess in the end worrying about those things is what mothers are for after all."

His gaze softened as he pulled her into his arms and hugged her close.

"I'll be fine, mom", he murmured as he deeply breathed in the comforting scent of her hair, savoring the small peaceful moment. "And just look at the good side. If the industry can prove what they want with the experiment they will finally be able to get into the efficient coupling and reproduction process." He pulled away to beam at her, an excited grin on his face. "Imagine how awesome it'd be if love was based on DNA! We will..."

"Yeah, yeah", she chuckled and rolled her eyes at his enthusiasm. "We will be able to prevent depressions, lower the suicide rate, cure psychological illness and accelerate the healing process in hospitals with help of the patients' soulmates that we can detect via a worldwide DNA data," she rattled off and gently pried her son's arms off her waist. "You already told me all of that. Like, fifty times a week."

He blushed lightly, but still raised his nose in the air in a superior manner. "Just wait and see. You won't belittle it anymore when they find your soulmate somewhere in Spain or Russia."

Her face dropped for the fraction of a moment before she smiled brightly again and touched his cheek lovingly. "You're so adorable, Blaine. But you're also a dork. And I can say that because I'm your mother."

He shook his head exasperatedly and waved her off.

"Yeah, whatever."

Ignoring the amused glint that appeared in her eyes at his childish behavior Blaine finished packing up rather quickly, squishing everything together so it all fit in his one big suitcase. He didn't want to arrive at the airport with a mountain of luggage to carry around, thank you very much. After his suitcase snapped shut with a satisfying click he grabbed it with his right hand and hurried down the stairs, calling out over his shoulder. "I gotta get going now mom, my flight is in two hours!"

"Are you sure you packed everything, sweetheart?", she shouted from the top of the stairs.

"Yes, mother!" You could literally hear the eye-roll in his voice.

"Towels? Your toothbrush? Underwear?"

"Oh my GOD! Yes, I packed everything!"

"Your mobile?"

"Of course I-" He felt his right jeans pocket. "...wait."

Blaine turned around just to find his mom smiling smugly and extending her palm towards him, holding – of course – his mobile phone. He grinned at her gratefully as he took it and put it away safely in his pocket.

"Where in the world would I be without you?", he sighed dramatically and she giggled.

"Either hospital or prison, that's where", she stated with a wink and nudged him towards the door. "Now go. Knowing you you'll manage to get lost in the airport like six times in a row. If you don't hurry up you won't have time to still check in after that."

Blaine would be deeply offended right now if that statement weren't so true. He chuckled and put on his shoes and jacket, his mom waiting in the doorway and holding his suitcase for him.

Before he left the house he opened his arms and hugged her close to his heart one last time. She snaked her arms around his waist in turn and clutched his back in that special motherly way that always had Blaine thinking if he should remind her that his ribs were anything but unbreakable. But to his own surprise he found himself returning the gesture with just as much fervor today.

"I love you Blaine, please be safe."

"Of course. Love you, too."

He waved at her as long as he could from inside his car as he drove away towards the airport. A funny feeling that had somehow settled in his stomach when he left the house grew more and more prominent with every mile separating him from home. Now that he was alone, without the comfort of his mother's presence, the nerves were finally showing.

He didn't know what he should or could expect to happen in the program he was attending for the next months. In fact he wasn't even sure if he would actually be picked as a participant, it was dependent on his DNA after all. But he had read the purposes of the experiment at work and immediately signed up. It was for a good cause and if he could offer his services he would, no excuses. Except the questioning of his decision that started nagging him now that he actually was on his way...

Blaine shook his head slightly to clear the unpleasant thoughts from his mind.

No turn back now, Anderson, he thought determinedly. You're going through with this, no matter what's about to come.

And with that he set his eyes firmly on the road again and concentrated on driving, quietly singing along to the radio.

"I can't sleep, let's run away and don't ever look back, don't ever look back."

When Blaine arrived at the hall that the company had rented for the meeting of the participants he was overwhelmed by the sheer amount of people who were already there. Men and women, old and young, businessmen and rather grungy looking people, seemingly from every single corner of the world. It had to be hundreds. He grabbed his suitcase a bit tighter in his hand, steeling himself before quickly making his way inside, avoiding a group of chatting men who obviously already knew each other. He sat down in one of the hundreds of chairs set up in several semi-circular rows around a big table. Now that he had a good view of the hall from the inside he couldn't help but be impressed with its sheer width. This place was fucking huge! Blaine had no idea how many people had yet to arrive in here, but if the mass of chairs was any indication he reckoned that there would be at least one thousand in total.

In the next half hour the seats around him filled up quickly with people chatting away as they waited for the meeting to begin. Blaine caught short snippets of conversation here and there, but didn't bother actually participating in one. He was actually still pretty tired from his flight, so he closed his eyes and decided to just rest for a bit while he could.

"May I call the brigade to attention, please!"

Well, that didn't last long.

Blaine looked up to see the tiny shape of the instructor standing on the table thing that seemed to be a makeshift stage, a stack of papers and a microphone in his hands. He held his nose up high in the air, a superior glint in his eyes as he let them wander over the crowd. Blaine decided on the spot that he didn't like this man at all.

"Dear Ladies and Gentlemen", he squeaked in a nasal voice. "I'm glad that so many of you decided to join in on our experiment. As all of you know the purpose of you being here is to find out whether love is based on the individual DNA of a human being or not. The proof that this assumption is correct would mean a revolution of a big part of our microbiology analysis that has the potential to improve our medical department drastically."

Polite applause followed his introduction. When it died down after a few seconds the instructor gestured to a guy standing behind the last row of chairs who nodded and switched on a slide projector.

"I will now inform you how this experiment is going to proceed."

The man pressed another button and the picture of several small houses lined up next to each other popped up on the wall. The instructor smiled at the audience and continued his speech.

"During the next three months we will separate you into groups of four. The constellation of these groups will be arranged by our medical cooperators, dependent on a few tests we will execute once I am finished with the instruction. Each group will live together in one of these houses" He pointed at the picture behind him. "which they can not leave unless they have a relevant reason like serious illness. The key to make this a successful experiment is that you, ladies and gentlemen, are not influenced by the outside environment, so we stay stern on that rule and bid everyone to obey it. In the three months you will spend together we want you to get to know each other as thoroughly as you can. If love really is based on DNA you will at some point show attraction to one of your roommates, your so called 'LIBN' which is the abbreviation for 'Love Interest By Nature'. We will sort two predicted LIBN-pairs into each group so one out of the three you will be living with is your complimentary partner. Your task is to find out which one it is. If the experiment ends in a positive result most of you will have found their LIBN at the end of these three months." He held up the stack of papers in his hand, casting a stern look at the crowd. "Once you signed this sheet you are committed to follow through with this experiment, no matter if you like our partner choice for you or not. Also, with your signature you give us permission to tape the development of your relationships on several cameras which we installed in the respective houses and agree that we are free to use the video material for studies and presentations. Please consider both of these points carefully for we will not accept belated objections. Are there any questions so far?"

Nobody raised his hand.

After a few seconds of silence the instructor clasped his hands together excitedly with a smug grin on his face. "Great. Then we will start our examination now. Ladies and Gentlemen, the first two rows follow me please."

He hopped off stage and waddled towards a door next to the table, the people in the first rows following him silently. Blaine leaned back in his chair and stretched his sore back. Sitting still for a long time always made him slightly weary and with at least eight hundred people in front of him also waiting for the examination he might as well take a small nap now. He had just closed his eyes when a tentative hand on his shoulder startled him.

"Hey!" A beautiful brunette girl around his age greeted him with a smile and pointed at the chair to his right. "Sorry to bug you, is that seat taken?"

He grinned widely back at her and shook his head. "Not at all, please sit."

She flashed him a grateful look as she plopped down and promptly took off her high heels. "Thank god!", she groaned when she had finally freed her sore feet from their confines. "My shoes are killing me."

He glanced down and raised an eyebrow, pointing at one of the shoes. "So that's what you call this? I could've sworn that thing is some sort of futuristic weapon."

She giggled and he smiled slightly, discretely letting his eyes wander over her slender frame in appreciation. That girl really was beautiful. If his LIBN looked anything like that he wouldn't regret joining this program at all.

"What's your name?", he asked, laying his hand on the arm rest between them, inconspicuously shuffling the tiniest bit closer.

"Kelly," she replied with a cute wink and lay her arm right next to his so that their shoulders were almost touching. Yeah, joining this program was actually the best idea Blaine ever had. He extended his arm in a kind of dorky way that didn't fail to make her smile.

"Pleasure", he said as she placed her hand in his and he kissed it gently, making her stifle yet another giggle. "My name's Blaine."

"Blaine, huh?" The playful glint in her eyes made her even more beautiful. "You know, when I signed up for this experiment I expected to find myself surrounded by ugly nerds, but now that I see you there is actually hope."

He laughed at the compliment. "Same here. Who knows, maybe we'll even get to spend the three months together."

"Maybe", she agreed and scooted closer, casually placing her arm against his.

In the following two hours Blaine was on cloud nine. Chatting with Kelly felt so natural that it was ridiculously obvious how much they fit together. She was smart, funny and – to top it all off – shared his insane love for music. He was sure that if love really was DNA based she would at least be in the same house with him, if not his actual LIBN. Blaine had never felt such an instant connection with anybody before. It just had to mean something.

When their group finally got called in for the tests he spontaneously grabbed her hand, relishing in the way she smiled at him and squeezed back. Sadly they had to separate at the entrance to the medical hallway, but not without the promise to meet again right after they were finished. Blaine walked over to the office of the doctor who had to test him with an excited bounce in his step, whistling some happy tune under his breath. Yep, right now life was pretty good.

The examinations lasted only a bit more than ten minutes, just a blood test and an overall check if his body was healthy. After he got his permission to join the experiment filled out he signed it and walked out the room to find Kelly already waiting for him with a soft smile on her face. They sat back in their former seats and were just getting into a heated conversation about Katy Perry's new album when the instructor got back on stage and cleared his throat, causing his audience to fall silent once again.

"Ladies and Gentlemen, we just got the results of your compared DNA information from the medics and finished sorting you into the different houses. I will now read out the group constellations and ask you to come on stage one by one. In the first house: Kevin Henson." A small brunette boy stood up and swiftly walked over to the instructor, receiving a nod and a key. "Harry Devor." Another – much more muscular – man strode over with a confident look on his face, clapping the first guy on his shoulder in greeting. "Nichole Torsh." A blonde woman walked over to the two men tentatively, shyly waving at them. "And Vanessa Lopez." Lastly a Latina with ridiculously long legs completed the quartet, her hips swaying left and right like a metronome as she strutted over to them. The Harry guy eyed her with unmistakable lust.

Kelly leaned over the whisper in Blaine's ear. "Well, I know who is going to have a fun three moths."

Blaine snorted and the pair broke down in giggles, looking up when the next names were announced. That was how it went on for quite a long time. The groups got their keys and walked down to the cars set up to drive them to their respective houses while Kelly and Blaine commented on who was probably gonna end up with who. The only change in their routine was when four women were called at once.

"I didn't know they were doing gay couples, too", Kelly wondered as she watched the four girls retreating. Blaine only shrugged.

"Well, it's natural I guess." But he diverted his gaze as they passed him by, somehow finding it inappropriate to look.

Now don't get him wrong, it wasn't like Blaine had a problem with gay couples or their display of affection or something like that. It was just that his father always talked big about how the divorce rate went up because of them or they were crowding the nightlife in his hometown and blah blah blah. Technically he knew that what his dad said was absolute bullshit, but he was still always a bit cautious when he saw a gay couple.

"House forty six", the instructor announced and Blaine looked up on the stage again. "Noah Puckerman."

A tan guy with a mohawk slowly rose from his seat, stretching his arms with a smirk on his face as he strutted over to the instructor like he owned the whole damn place. He took the key and looked down at the crowd, making bedroom eyes at a few girls in the front rows who started giggling and waving in response. Blaine rolled his eyes. Hopefully he wouldn't get paired up with-

"Blaine Anderson."

Well, fuck. Sighing deeply he smiled at Kelly one last time before he confidently walked over to the bad-ass who greeted him with a smirk and a fist bump that Blaine returned with a grin. Maybe he could just get acquainted to this and the next months wouldn't be so bad after all. He looked out into the mass of people staring back up at him, curious what kind of girls would stay with them in the house. He caught Kelly's eyes from the distance and waved at her, silently crossing his fingers. Please let it be her, please let it be her, please let it be-

"Finn Hudson."

Wait, what?

Blaine frowned deeply at the instructor. Since when was Finn an unisex name? He'd never heard of that before. Blaine furrowed his brow in confusion as he let his eyes wander over the crowd again, searching for the girl appendant to the name.

"Finn Hudson?", the instructor repeated when nobody stood up, a slightly annoyed undertone in his voice. "Hello? Finn Hudson?"

The crowd was silent for another moment and Blaine was just coming to the conclusion that this must be some sort of joke when suddenly a freakishly tall guy stood up, confusion edged all over his face as he made his way towards the stage.

"What the hell?" Blaine heard the mohawk boy – was it Noah? – mutter next to him, voicing exactly his train of thought.

This had to be a mistake. Or another procedure of the experiment. But then again that made no sense, the instructor would have told them in the beginning. Surely they weren't meant to share a girl between the three, were they? Were Noah and Finn gay? He was just about to ask the instructor when the short man continued unfazedly with the fourth name, that stupidly smug grin from before prominent on his face again.

"And last but not least, Kurt Elisabeth Hummel."

To Be Continued...
