"Ow! Stop That, Soulmate!" Karamatsu x Reader (Soulmate AU)

(Soulmate trope : You feel the same pain/injuries as your soulmate)

—•—•—•—•—•—•—•—•—•—

You've been friends with the Matsuno sextuplets for almost two years now, you just couldn't believe how time flies by so quickly!

They were all so hilarious in their own way, they've made you laugh, cry, mad, disgusted and all sorts of emotions. But the most of all is that you felt at home every time you're with them.

You've even started to get a few little crushes on them. But your crush on them changed throughout the time, last month you liked Choromatsu, three months ago you like Jyushimatsu, last year you had a massive crush on Ichimatsu.

But at the moment, you're starting to have feelings for a different brother, the 'probably most hated' brother. It was the most painful and cringey person you've ever laid eyes on. His name was Karamatsu and you honestly didn't know why you started liking him that way. At first you would always roll your eyes whenever you see him do something but after the last few weeks it looks like your opinion had completely changed.

Something about having a crush on Karamatsu felt....right. You don't know what this feeling is but it's different from your past crushes. It feels like you two were meant to be and you wanted so badly to be that way.

Lately, something weird also started happening. You've been feeling pain around you in random body parts at random times. For example you feel someone punching your stomache but no one was even in front of you, you feel like you got slapped but no one slapped you or was even around you.

It weirded you out alot, you've been getting a few bruises even!

You've had countless of nosebleeds, black eyes, and bruises coming out of nowhere. You became really confused and started feeling depressed because of it, you couldn't take the feeling anymore. You didn't want to feel pain at random times, you just wished this would all stop. You obviously told the sextuplets about this, they were just as confused as you are.

You used to be taking care of yourself really well, you've barely gotten hurt or get any bruises, not even a single scratch. It was strange, verrrryy strange.

One day, you were chilling with your sextuplet BFFs. Just sitting by the Akatsuka table and checking your phone while the brothers did their own thing. You haven't gotten hurt just yet which is a pretty good sign, usually they come up every two hours or so but this time it's been oddly going okay.

"My dearest Burazzas and (Y/N)! I would like to go get some snacks from the kitchen if you'd all let me!" Karamatsu says as he stands up, most of his brothers just groan at his weird 'speech' while you tried to hold back a chuckle.

Then Karamatsu left shortly after, it was still as normal as before until you feel your toe aching.

"Ah! Oww.....seriously? It was going so well today....." You hissed through gritted teeth as you held your red toe.

"Something wrong, (Y/N)?" Choromatsu asked, you nodded unsuringly.
"Yeah.....those weird sudden pain things are happening again, it feels like I stubbed my toe but I didn't...." You sighed as you carress your toe. Then Karamatsu walked back in the room with snacks filling his arms.

"I'm back my Karamatsu girl and boys! Sadly I've stubbed my toe on a chair whilst in the kitchen but heh, I'm fine!" Karamatsu said with a thumbs up, you were surprised a little that he stubbed his toe just like you did but you shrugged it off.

The seven of you ate some chips and choclates and other snacks, it was pretty good. You never realized that they have such good chips, after you ate some snacks, you felt like needing to go to the bathroom so you excused yourself.

As you finally reached in front of the bathroom door, you felt like someone just smacked you upright on the head.
"OW! Fuck!" You yelped in pain, then you feel someone push you with a hard force. Greaaat, these random pains are coming again, you thought.

But this was a lot more worse than before, you couldn't even get a hold of yourself. You feel someone tugging on your shirt and getting punched in the stomache. You lost your balance and fell onto the floor as you tried to get up but you were still getting beaten up by no one.

You crawled, trying to go downstairs and get help from the sextuplets. But once you made it to the stairs, you feel someone kick your hips. That's when everything went black as your aching body rolled down the stairs with horrifying thuds.
It felt like you were falling down for an hour, it all happened so quickly yet so slowly at the same time. As you reached the floor, the random sudden pains disappeared into loud silence.

You could barely move your arms and legs, you were silently crying because you couldn't move your muscles. Then you hear some noises from the other room, the one where the sextuplets were.

"Karamatsu nii san?! Are you okay....?"
"He can't move!"
"Did we hurt him too much.....?"
"What are we standing here for?! Help him up!"
"Okay Karamatsu, here....."

What happened to Karamatsu? You started to wonder what's going on. Then you got your courage together and yelled out to them.
"GUYS! HELP ME!"

Then you hear running footsteps going towards you, you feel someone trying to pick you up. But you couldn't move at all, even if you move a single muscle it's still so painful. You looked up and see five of the brothers except for Karamatsu, they all looked so worried.

"(Y/N)! Did you fell off the stairs?!" Asked Totty with an expression filled with worry. You nodded your head slightly. You sat up on the floor slowly as you rubbed your aching head.

"Wh-where's Karamatsu....?" You asked them.
"He's in the living room still. We don't know what happened to him, all six of us were fighting and hitting eachother over the last bag of chips and then he suddenly started yelling like he's hurt or something and fell to the floor, even though we already stopped fighting eachother!" Osomatsu said woth a shrug, you tilted your head confused.

You slowly got on your legs with the help of the five of their arms and walked back to the living room with them, you look at Karamatsu and he had bruises. But....what was strange is that his bruises were quite similar to yours.

"Eh? My dearest (Y/N) chan what happened?!" He said with wide eyes, you chukled.
"I could ask the same for you......"

"Okay guys, me and the others will go look for some spare bandages. You two stay here!" Said Jyushimatsu as he and the others left the room, you looked at Karamatsu and he has a black eye and a bloody nose just like you.

"Long story short.....those random sudden pains happened while I was going to the bathroom. It felt like someone was punching me and kicking me and strangling me....." You sighed, although the person in the blue hoodie had wide eyes at your statement.

"O-oh....uhmm, (Y/M) may I ask what happened next....?" Karamatsu asked you, he looked like he was desperate to know your answer.
"Ah, well I accidentally f-fell down the stairs" You said with a chuckle, Karamatsu raised an eyebrow in shock. You didn't know what he was doing or why his expression was that way, it looked like he cracked a case of some sort.

"What? What's with that shocked expression?" You raised and eyebrow, Karamatsu then started rubbing his chin with his thumb and index finger.
"I need to test something" He said, you were much more confused now on what he meant.

"Ooookaaayy......?" You shifted your eyes to the side in confusion. That's when Karamatsu suddenly lifted up his index finger and BIT IT!

"OW! Hey what- huh....?" You yelped in pain but that pain suddenly goes away and was taken over by more confusion. You and Karamatsu looked at eachother with wide eyes, you blushed bright red and rubbed your arm.

"You feel the pain on your finger too, did you?"
"Y-yeah I did...." You mumbled shyly, Karamatsu smiles with excitement.
"Oh wow, heh. I didn't know my true Karamatsu Angel would be my Soulmate....."
