Enmu X Muzan

Closer

Few minutes later i hear the door slamming, then a biwa sound. He probably left. I slowly get up, though it feels horrible. I stay still for a little, and as i get used to it, i walk to the door. I peek outside. He was gone. Where should i start? I am now in the living room, it also has big windows, a huge couch, a wooden desk with a fancy chair, and a few book shelves. It's pretty big... I notice a door on the front wall, so i decide to go in.
Behind the door there is a huge "library", i guess Lord Muzan works here... On the middle there's another wooden desk, but besides there are only book shelves. I start walking around them. The books he had are mostly very expensive, well known and hard to get.
As i keep walking around, i notice one that i've been interested in since a long time. I try reaching for it, but it's too high. It exhausts me again. I look around, and see a latter-like thing, so i take it to the right shelf. It was heavy, and lifting it highered my pulse, so i stop for a bit, then climb up and take the book.
Right when i put the "latter" back, my entire body starts throbbing. I can't breathe. My throat burns and i can hear my heartbeat. I squeeze my hand against my chest as i'm trying to catch my breath. Every single try stings it. I squat down, then fall on my knees trying to relax my muscles.

Muzan POV

I take my coat on and i'm leaving already. I hear a biwa sound and i'm on the streets. There was a hashira i had to take care of, he was killing too many of my demons, and i wanted to handle it myself. I left an eye on Enmu, of course, in case anything happens. He's stubborn enough to do something stupid while he's recovering.
I walk into a small dark road, near the area i found the hashira before. He's already there, with another demon slayer. They just finished a few demons off. I was just about to approach them, when i felt the poison kicking in on Enmu. I block immediately. I knew this was gonna happen! I shouldn't have left him alone there! I start thinking hard.
I experimented using telepathy with my demons since a pretty long time, but it didn't really work. I have to try anyways! I focus hard.
Suddenly, i'm inside my room. It worked! I can't believe it!
I start running up to Enmu. I find him kneeling on the floor, struggling to breathe. It makes me want to cry. I squat down next to him, and put my hands on his shoulders. He looks up at me. His face gets tears in my eyes. I hate seeing him like this! I wanted him to be safe, and here we are!
His body overheated. "Let's go outside, it's very hot in here" i tell him, as i try to pull him up, but his legs are still weak and he falls back on the ground. I pick him up and he wraps one of his arms around my neck, holding his chest with the other.

Enmu POV

He puts me down on the couch, which is next to the middle window. He places me nearest to it, then opens it wide. Cold air comes from outside. It's soothing. My body slowly cools down, and breathing gets easier. The only thing not changing is my heart rate. It's pounding even faster, since Lord Muzan is sitting right next to me~! He puts his hand on my back. How do you want me to calm down if you keep doing such things?!
"Are you feeling better?" He asks, slightly caressing my back. I nod, since speaking is still a struggle. "I told you not to overdo anything! Wisteria is not just like rotten food for a human! You should take this more seriously!" The way he suddenly lifts his voice scares me for a second. "I-i'm sorry...i didn't know something this small would cause this..." I'm waiting for a second scold, but he doesn't say anything. I keep looking at the floor.
"No...I'm sorry...i shouldn't have come at you like this...you couldn't have known...I apologize..." His words shocked me even more than the voice lift. I don't think I've ever heard him apologizing for something.
He lays his head on my shoulder. At this point I'm as red as a tomato. What?? I start considering again, if this is just a dream. Would he ever do something like this in real life? No...there's no way...
"I'm just glad I got here in time" he says warmly. Every single word coming from his mouth and every small movement he makes is making me blush even more. My body feels overheated again...but it's kinda comfortable. I don't want him to lean away..."I-I don't think...anything s-serious would've happened..." I try to say what's on my mind, but it's hard to think while he's so damn close! I can literally smell his hair~ it's so nice~
He interrupts my daydreams by leaning away. Aaagh why did it have to end?? I look up at him. His face is still about two inches away. My heart is beating so fast it wouldn't even surprise me if he heard it...he can read my thoughts if he wants anyways, so i shouldn't care, i guess...
"Go back to bed for tonight. You need to rest" he says with a smooth (criminal) voice. Noo~! I don't want to be alone there! It was soo nice to be next to him...but he's right...I am really tired... I just wish it would've taken longer~
"Okay" I answer. He stands up with his hand reaching for mine. I insecurely hold his hand, and he pulls me up gently, then emraces my shoulder and leads me to the bedroom. He's so warm~
I get in the bed, sitting. "Sleep. You didn't rest so much before either." I nod. "Thank you for helping me again" i say, kinda feeling awkward by him always seeing me like this...always needing help... "It's my pleasure. But please take better care of yourself!" He looks worried and serious at the same time. "I will" i say smiling. He kisses my forehead. That catches me off guard. My eyes flick open, and i forget to breathe. "Good night~" he says softly, like nothing happened, then leaves the room, not even looking back.
I look in his way confused...where did that come from?? I slowly lay my head on the pillow, and my confusion turns to an overwhelming happiness. My heart is pounding even faster, and I'm on the verge of screaming. I close my eyes, still smiling like an idiot, and after a few minutes i manage to fall asleep.
