Rei x Reader: Tingles

"For the last time, please tell me what is the definition of photoelectric effect." Rei massaged her temples
"Umm, The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons." You squeezed your eyes shut, trying your hardest to remember the definition(A/N:Fuck Quantum Physics)
"Good Job. How about we take a break? Jihyo's café is near by isn't it?" Rei offered, as you giggled, nodding.
"Oh my god I love you so much Rei, YES!" You exclaimed, Rei trying to hide a not so subtle blush as she too nodded.

Rei wasn't what you would call someone who was open to love. She never let anyone steal her heart, come close to it, but you stole it when she saw you from a far. Rei couldn't believe it. While she had never been hurt romantically, she had always thought of love as a weird, foreign feeling. As a stout believer of science, to her, love was just a bunch of chemical reactions in the brain that makes someone think they're in love. All that changed when she saw you, that once stout belief in her idea of love shattered when she first laid her eyes on you. How someone could seem so perfect, ethereal, magical, it evaded her, irked her even. She found it hard to approach you, especially out of nowhere. She was sure you'd peg her as some creepy girl and brush her aside, but as fate would have it, the door opened for Rei, an overheard conversation between you and your lecturer about your rather uncharacteristic poor performance in Physics. Rei left you a note in your locker, offering Physics help. Needing all the help you can get, and also wanting to get close to the enigmatic girl who would appear and disappear with the bell.
As the days went by, and the tutoring sessions increased in frequency and length, the two of you began what some might call a rather unlikely friendship. Both of you were introverts, and to an outsider, watching the two of you hang out might seem awkward, the two of you seating together silently, no words exchanged. Knowledge that was only privy to the both of you, however, was that the two of you found the comfort in each other's silence, Rei resting her head on your shoulder, desperately trying to quell her thumping heart as you hummed a soft tune to let her rest.

"Unnie! Can I get two Frappuccinos?" You shouted across the counter, Jihyo rolling her eyes as she worked the register
"What did I do to deserve a freeloader for a sister?" She chuckled as you pouted, hands on your hips as you turned to Rei, hearing her laugh at Jihyo's comment.
"Whatever Thomas." You smirked, seeing Jihyo's face morph into one of mild disgust
"Jeong! One Frappuccino, and another one with a dose of Cyanide!" 
"Hey Y/N!" Jeongyeon shouted from the kitchen as you chuckled, heading back to the table with Rei
"So, how's things been going Rei? I heard someone from S26 is interested in asking you out." You smiled, hiding an ugly bubbling feeling in your chest
"Ugh, I don't know, seems like these rumours pop up every other week now." Rei rolled her eyes, well aware of these rumors, Gauel had her ears to the walls like that. It frustrated her, but not in the way one would assume. Rei had been irked by these rumours, fearing that you would think she was actually interested in someone else, or would ask someone out, even go as far as to set her up with someone. All she wanted was the nerve to ask you out, but it seemed to escape her.
Rei's train of thought was interrupted by the ringing of your phone, as you excused yourself to receive the call.
Three cups in hand, Jihyo walked over, Rei clearing the table for her to set the beverages down.
"So which one of these has the cyanide on it?" Rei quipped, Jihyo chuckling as she handed you a cup, pointing to the other.
"So, Y/N's pretty slow huh?" Jihyo asked, sipping the cup still in her hand
"Nothing to worry about Jihyo-unnie, Y/N's doing fine, progressing pretty well. Y/N's grade is going to improve, I promise." Rei reassured Jihyo
"Well first of all, just Jihyo is fine. Secondly, and more importantly, I'm not talking about Y/N's grades." Jihyo chuckled
"Then what do you mean?" 
"I'm talking about your little crush on Y/N." Jihyo said with a smirk, Rei spitting her coffee out
"What-What I don't...don't know what you're talking about" Rei muttered out, averting her gaze
"Oh please Rei, Y/N might be dense, but I'm not. I'm observant like that you know? That's how I see the way you look at Y/N, the way you light up when Y/N smiles, or laughs. And I'm observant enough to know that Y/N feels the same." Jihyo continued sipping her coffee, a smirk on her face as she watched Rei go through about 32 stages of confusion. 
"Ask Y/N out dummy, I promise you it'll work out fine." Jihyo smiled reassuringly, resting her hand on Rei's shoulder, a small smile on her face.
"Aish, stop bothering my bestie Unnie, shoo!" You quickly rushed Jihyo away, Rei turning to compose herself, hiding her blush from you.
For the next hour, you and Rei engaged in casual conversation. Well, you did, Rei mostly smiled and nodded, trying her best to hide her turbulent thoughts as you talked, as she found her thoughts lingering on you, your smile, your eyes, your lips, you. It took all of Rei's willpower to hide the blush on her face.
You had noticed Rei's sudden silence, cursing yourself internally for rambling on for so long and probably seeming weird to the Japanese girl.
"Rei, it's getting dark, how about I send you home?" You offered, as Rei nodded, the two of you saying goodbye to Jihyo. With a thumbs up and a reassuring nod, Jihyo gestured toward you, Rei nodding, Jihyo's smile beginning to touch her eyes.

"Wait, Rei, where are you going? Your house is that way." You asked, confused as Rei turned.
"I want to ask you something, come on!" Rei said with a smile, grabbing your hand as she pulled you along with her, your body in shock at Rei holding your hand.
You smiled as you saw Rei smiling like a child, rushing to two empty swings as she began to swing gently, gesturing to the other swing. Sneaking a quick picture of her, you sat next to her, watching as her face lit up, smiling with affection.
"So, what did you say you wanted to talk about?" You asked, as Rei slowed her swing, closing her eyes as she not only appreciated the tranquility of the silence at the swings, but also coming to terms with the weight of what she was about to do.
"Look at the stars. They're so pretty tonight." Rei said, her eyes traced onto the stars in the sky, you followed suit, smiling. Rei was right. The stars were pretty, but not as pretty as her.
"Yeh." Was all you could mutter out, as you cursed yourself for your inability to speak. The universe gave you the best opportunity to confess, and you squandered it. Good going...
"Some people say stars hold the key to our future. So at night, whenever I look in the night sky, I look at the stars, and think about the future, and what it holds for me. And you." Rei said, reaching over to hold your hand in hers.
"And me and you." Rei smiled as she looked at you with both love and fear.
"And-And that means what?" You shook your head, confused about what Rei was trying to say.
"It means, I want us to have a future. Together. As more than best friends."  
Rei chuckled a little as she looked at you sitting there, slack jawed, stunned as you tried your best to process what Rei just said. Rei could have sworn she saw smoke coming from your ears.
After a while, however, Rei began doubting what she had just done. Had she just messed up everything?
"And if the feeling isn't reciprocated, I understand, I just wanted to get this off my chest, and I understand if you don't like me back and..." Rei began rambling, before finally being stopped by your hands on her cheeks, holding her gently
"You talk too much sometimes Rei." You smiled gently, Rei smiling back, before a look of uncertainty flashed across her face once again.
"So...do you?" Rei asked, before feeling your lips on hers, as the two of you shared a romantic kiss.
"I do." You whispered, Rei still blushing as she tried to comprehend that she had just kissed her long time crush
"I do? We're not married yet you know?" Rei quipped, chuckling before recoiling in shock as you got down on one knee.
"No time like the present right? Naoi Rei, Will y-" You were about to finish, before you heard a loud shout from behind you.
"No No No, the two of you are much too young for this!" Jihyo shouted as she ran towards the two of you.
"Aish, Unnie, I was just joking around, and, wait, were you spying on us?" You questioned, as Jihyo had a goofy grin on her face.
"Well, who do you think gave Rei the push to finally confess? Well, it had to be one of you confessing, and you were too much of a loser to do it, so I had to ask Rei." Jihyo said, slinking her arm around Rei's shoulder as the two of them high fived.
"Well, I guess you did good this time Thomas." You said, as Jihyo glared at you, turning to Rei.
"If my dumbass sibling ever does anything, just come to me, I'll always take your side over that idiot's." She whispered, but making sure it was loud enough for you to hear.
"Hey!" You shouted in jest, as Jihyo chuckled, before heading off.
"So, where were we?" Rei asked, holding your hand in hers.
"Well, since I am a sucker for making things official, Naoi Rei, will you be my girlfriend?"
"I do."

"Yujin Unnie, can we switch spots, I'm about to throw up." Leeseo groaned as she gestured to the two lovebirds she was forced to sit next to, Yujin chuckling as she looked at both you and Rei resting your heads on each other.
"Umm, love birds, you can just put your hands on the table, it's pretty obvious." Gaeul chimed in as Rei giggled, pulling your two intertwined hands from below the table, resting it on the table.
"Jagi, could we head out for a while? I want to do something that Leeseo is too young to see." You whispered, but Leeseo still overheard, mock throwing up as the two of you ran off, hiding in a little cubby.
Holding Rei, the two of you swayed to the tune played in the store nearby, before you pulled her in close, leaving a light kiss on her forehead.
"Have I told you how much I loved you?"
"Only 12 times today."
"Well, make it 13."
