I'm sorry for this | {Kokuzan}

Theme: Fluff + Angst 

Note: The stupid wheel chose this to be fluffy angst of holidays and execution so let's see how this plays out 💀 I'm sad bc idk what to write-

Demons usually don't give a single fuck about holidays. They're just stupid days that humans use as excuses to take off of work or school or whatever. Sometimes celebrations that leave them drunk and wasted. Easy prey. But sometimes demons did celebrate them. Although, not exactly celebrate as much as acknowledge. This was one of those times.

It was a silly little holiday. Valentine's day. The one that people meet up, give chocolates and flowers and gifts. Typical lovey-shit. But this time Muzan decided to 'celebrate' it as well, which was extremely unexpected of him. As nearly nobody knew, he was dating Kokushibo, his oldest (if you ignored the traitor Tamayo), strongest, and his personal favorite demon. He didn't know what to do, so all he did was put some nicer clothes on—the ones he had on before were drenched in blood. Then he went in search of Kokushibo. He found him quickly and demanded that the Uppermoon must come with him somewhere. For Valentine's day. Kokushibo agreed. He had forgotten that 80% of the time, people do things with ulterior motives. 

Muzan and Kokushibo traveled for a little, walking and teleporting equally until they reached this one site. It was old. Very old. There was the remains of a building left there, and besides that there were just trees for miles and miles. "Eh, Master, what is this place?" Kokushibo hummed, confused.

Muzan said nothing and just nodded for Kokushibo to keep going. They went inside the pit of the broken down building and sat on these makeshift chairs they made by stacking up the rocks. Then Muzan said, "Kokushibo. Do you trust me?"

"Huh-? Yes, yes I do," Kokushibo said, more confused than ever.

"Good." Muzan pondered how to go through with this when he had an idea. "Okay, uh... Here," he said, holding out some flowers he'd messily snatched on the way there.

Kokushibo took them, surprised. "Oh! Thank you," he said, a small, teasing smile playing on his lips.

Muzan ignored it, feeling slightly flushed. Then he cleared his throat. "Uh.. If you want you can.. have some of my blood? It will make you stronger too," he said quietly.

Kokushibo thought his mind was playing tricks on him. "Really??" he asked.

"Yes. Yes, sure, of course," Muzan said, stumbling over his words. 

Kokushibo waited for Muzan to hold out his hand and drop blood into his mouth or whatever, but it didn't happen. He cocked his head, confused, when Muzan realized he should clarify. He tapped his neck and Kokushibo looked at him, perplexed. "Ah.. could you explain, please?" he asked.

"Oh. Uhm. Just- Just bite my neck," Muzan said awkwardly. He quickly added, "ONLY because I don't feel like puncturing myself. That's it."

"Right, okay," Kokushibo said nervously, standing up. Muzan did as well and then sat on the stone tabler, waiting. Kokushibo placed his mouth on the side of Muzan's neck and gently bit down, drawing blood. He didn't take much and tried to do the least damage, wanting to make sure Muzan wouldn't get angry or something. He quickly sat back down as his body processed the blood that slowly flowed through his veins and strengthened him. He tried not to make a sound as the blood caused pain throughout his body before it settled. Kokushibo looked up and saw Muzan, still on the table, covering his mouth and flushed. 

Kokushibo was confused at this, but said nothing as the pain started subsuding. Muzan continued looking flustered, his face slowly burying in his hands. Eventually, Kokushibo was able to speak again and he cleared his throat. "I.. Thank you, Master," he mumbled.

Muzan nodded slowly and took a deep breath, then slid off the table. He walked over to Kokushibo and promptly sat on the Uppermoon's lap, uncaring of what Kokushibo thought of this. It was certainly a surprise and Muzan's demon was very flustered at this action, not having expected it.

The play of small affection continued through the night for a while. Eventually Kokushibo completely forgot about dawn and only just enjoyed his time with Muzan who was playing his role carefully. Now, only a few minutes till dawn, Muzan said, "Kokushibo.. do you trust me?"

Remembering the words, Kokushibo nodded quickly. "Yes, I do."

Muzan nodded. "Good," he said, the same as before. "Kokushibo, stand here and close your eyes. If you feel warm, it's not the sun, okay? I promise," he said, with so much conviction Kokushibo didn't question this. He just nodded and closed his eyes, standing still.

Muzan nodded then went to kiss Kokushibo but realized he was too short to reach him properly so he went over and stood on a stone. He places his lips on Kokushibo's and then pulled apart. Kokushibo had been surprised by this but smiled at it. 

He heard the sound of scraping stone and figured Muzan was just moving the rocks around a little to get through it more easily. Eventually he heard the sounds of footsteps and they seemed to get a little more quiet with each step. "Master?"

Muzan's voice sounded a little more distant as he called back, "One minute, I'll be ready in one minute. You can open your eyes in one minute, when I say so, okay?"

Kokushibo hummed his agreement and waited. One minute later, he felt a strange sensation. It was warmth, a weird warmth. One he didn't like one bit. He heard Muzan shouting that he could open his eyes. And he did. And he realized Muzan had set him up to.. kill him. The sun rose above him and he went to turn to find a way where he could hide but he found he was surrounded in every other side by rocks, the rocks Muzan had moved earlier. Where there were no rocks was rope tied around to make it harder to climb through them, and above him were more rocks which were tilted in a precarious way. 

"Why..?" he mumbled. "WHY!!"

He vaguely heard Muzan saying, "I'm sorry for this, Kokushibo. But it's for my sake. Besides, you trust me, no?" before he crumbled to dust.

Muzan sighed as he hid from the sun. He did like it, being with Kokushibo, but he couldn't risk Kokushibo turning into Yoriichi, so he did this. He had to. It was a necessary precaution.

He turned away and walked off as if nothing had happened.

My sister's mad at me for writing this I think 💀 She's shitting on Muzan now- I was saying he used the sun to feel less guilty but she took none of it and said that nobody cares. She just said "Seriously, Muzan, you could've killed him on a different holiday!! Seriously, nobody cares about your stupid fears!! You're literally the worst boyfriend ever!! 🙄" 

I'M LAUGHING THE WAY SHE ACTS SO SASSY WHEN SHE SAYS THINGS LIKE THIS AHAHAHAH

Anyways bye 🫠 I tried but imo I failed at writing this but who cares anymore 😋
