Kimetsu No Yaiba x Reader (Alternate Universe)

Sanemi Shinzazugawa x Reader|| Nightmare

"Gah!" Lashing out under the blanket. It woke you up as well, Sanemi was fighting the blanket while he was wrapped under it. You spoke up while turning on the lamp light.

"H-hey! It's me! It's me!" You threw it off just to see him sweating. He was panting then shot up and rubbed his face. He seemed very tense. You went to put your hand on his shoulder and he just kicked his feet out of bed.

"Dammit..." he hissed and got up. Rubbing his eyes and leaving the room. He went to go get some water from the kitchen while you waited in bed, tired but wanted him to come back. As you waited, you pulled the lamp switch and laid down. Sanemi eventually came in and then went straight to the bathroom. He closed the door. You watched and he didn't even say a word. When he came out, you were by the door. He freaked. "Oh my God!" He threw his arms about, it was his reflexes that had him attack what startled him but since it was you, he redirected it to the door frame. "Why aren't you in bed?" He questioned. You looking irritated.

"I should ask you the same." Your hands on your hips. He sighed. He leaned against the door frame he dented and looked down at you. He looked tense still.

"Hey.. what's wrong?" You inched closer, having your body press against his. Your arms crossed as you looked up at him. He made a deep sigh and rolled his head back,closing his eyes.

"Don't make fun of me..." he growled.

"It depends..."

"I had the most nerve racking nightmare." He mumbled but you heard him, though you wanted him to be more clear.

"A what?"

"A nightmare, (y/n)." He turned away this time but he was definitely more clear about it. You laid against him and gave him a warm hug.

"We can cuddle it away?" You suggested. He looked down at the top of your head before you nuzzled into his chest. Her comfort relieved his stress but he worried. His dream was surreal, the more he thought about it his heart pounded faster. His arms wrapped around you and he carried you to bed after turning off the bathroom light.

"Alright. What time is it anyways?" He'd ask.

"Uh......" you rolled over to look at the clock. "We did sleep early... it's 2am right now." You said. He sighed and grabbed you. He pulled you into his body and you ran your fingers through his hair.

"Let's try this again..." he said and yawned before closing his eyes. You immediately crashed after finally being back in bed. Getting up after being awake for no reason drains you.

Through the night, you felt his grip on you tighten, your hands guided themselves to then caress his cheek. His face felt wet, was he crying? You continued to comfort him. You didn't know it would get this bad but it was as if he jumped right back in. Your comfort though kept him asleep since he did need to get up early for morning classes.

"(Y/n)...." He mumbled. He was still sleep so you just listened to him talk as well. You wondered what was going on in his dreams to have him so on edge.

"Genya... please..." he groaned. It worried you. Seeing him so hurt over an illusion made you adjust him on his pillow and cuddle him to his heart. Your head up his chin as he laid back. He was sweating from his head so letting him breath was probably going to help him cool down. It kept you awake since you listened to his words. You were committed to ask him in the morning about his nightmare. Eventually, the two of you had officially crashed for the rest of the night.

Even though you ran on at least 6 hours of sleep, you got up to make breakfast for Sanemi. He appeared to have calmed down and sleep peacefully which was nice. He was to wake up 15 minutes after you have so you tried to cook fast or at least be close to done.
A yawn from the hall and there was the sleepyhead looking at you with one eye open. He looked really tired and came over to you, and hugged you from behind. You scooping breakfast on a plate and turning off the stove.

"Good Morning, Darling.." you said quietly. He just went 'hmm' into your neck and continued to hug you. "Go ahead and take your plate. Don't want you to be late for class." You mentioned. He did so and killed breakfast within minutes. During the time, you cleaned the dishes you used and asked. "Darling, what was your nightmare about?" You asked. He looked at you then looked down.

"Dammit, I was hoping you wouldn't ask." Was his response as you pulled the plate to you. You continued to wash the dish. Waiting for his response and now turning off the water. There was a silence as the two of you were now looking at each other. "Fine."

"C'mon. Why keep it from me?" You titled your head and leaned against the cabinet, using a cloth to dry your hands.

"I'm not trying to. I just still need to remember what happened. It was just so sudden." He explained and got up from where he sat.

About a year ago, Genya, Sanemi's little brother had got caught in a crossfire when coming home. He was such a good kid and was only so far from home so Sanemi saw it happen from the window. He'd usually check when Genya starts to be late and when he saw it happen, he'd jumped out the window to start swinging. It has traumatized him greatly but he hasn't let it get to him. The dream he had, he did mention his name. You didn't want to say it first but for him to talk to you about it. You crossed your arms waiting for more.

"I just saw my brother. He was still alive and you know what happened." He explained while standing only so far from you. You saw his hands ball into a fist. Frustrated. You extended your hand to brush against his, then intertwined yours into his. He didn't look at you still. "It was then, I started to notice you started showing up in such a setting. It happened in front of me again and I was too late." He turned to look at you with the final words coming from his lips. He hugged you tightly, slightly shaky. "I can't stand more things being taken away from me. I always wanted to see Genya grow up and become a man he would eventually come."

Your arms went to hug him as he continued to vent heavily. His tears falling on your shoulder and his grip slightly tighter around you.

"You being apart of my life worries me.'I don't regret every meeting you and I've become so close to you that I want to grow into something with you. If I lose you to, I don't know if I could even keep going." You both kept the emotional hug. He was trying to hold back crying but it still came out. He was devastated by his own mind getting to him. You let him have the moment to let it all out before speaking for reassurance.

"Sanemi-kun.. My Darling." You started with your hands lightly going through his bed head. "I know you feel bad for what happened to Genya and that the world has been so cruel to you, yet don't think the world is going to take me from you." He took his face out from your shoulder, ready to protest. Instead you lightly choked his cheek.

"The world is gonna have to do more than throw slaps and punches cause I'm strong, y'know!" You exclaimed. "I'm not gonna let life pin me down whenever the situation comes. I will keep fighting and fighting just to be by your side as well!" He raised a brow.

"Now you sound like a dumbass protagonist." You froze. "Tch... Why're you so silly...?" He smiled after the tears and came in to kiss you passionately. Surprised by the kiss, you kissed him back but then shoved him. "THE FUCK?"

"You have class!!" You pointed at the time, flustered still.

"Oh, shit." He ran to the room and then exited at least 15 minutes later in uniform. Before stepping out, he hugged you tightly and kissed you more. He smelt so good... "Don't get me distracted,(y/n). I'll get to you later." He harshly pinched your cheek then stormed out the door.

"Ow~... jackass..." you complained and locked the door behind him.
