Things had been disappearing recently from the Tsugikuni household. Obviously, it was a thief. Nobody who had direct contact to inside their house would do this, especially since it was already theirs. 

They didn’t have bodyguards because they’d never bothered with them—or more like Michikatsu and Yoriichi were expected to be able to take care of themselves being both boys nearing adulthood.

So someone had to be sneaking inside, past the security cameras, and stealing their things.

And unfortunately for Michikatsu, he was put up to the task of staying up at night to find whoever it was.

Michikatsu had dropped out of school (much to his parent’s disappointment, but he hadn’t given a fuck and had already acquired a job anyways, which had interfered with his studying) which meant he didn’t need to be stressed about some stupid thief ruining his sleep schedule.

Yoriichi had offered to help but their parents had given him a hard no and made him go study. 

Not that Michikatsu was all that jealous of him, but he just would rather sleep.

But now he was stuck pacing around the front door and the windows at night, waiting for something to happen. 

The first night, absolutely nothing happened. When he was awake, at least. He’d fallen asleep half way through the night and woke up with his mother scolding him and his father irritated that the thief had stolen something again.

The second night, Michikatsu lasted a lot longer since he’d slept during the day—he’d been given a day off for work—and he was energetic when he’d woken up. Nevertheless, he’d not caught the thief yet again, albeit they’d managed to steal a box of jewlery somehow through the night.

The third night, again, he made no progress. This continued on for a while before Michikatsu finally met this thief for the first time. 

He had been wandering around his house quietly, his ears perked and catching every small noise around him.

He’d hidden in a corner of his room at one point, hoping he’d catch the thief red-handed.

And then his window had opened. 

A boy—a lot smaller and thinner than Michikatsu had thought he would be, although perhaps that was how he got around the security cameras—slunk into the room, searching. 

Michikatsu held his breath, wondering what he should do. 

The boy looked around, his eyes catching on something out of Michikatsu’s vision. He turned away from him and Michikatsu moved slightly, hoping to catch him.

But then, quick as light, the boy was at Michikatsu’s side, a small pocket knife at his throat.

“Oh… You’re Michikatsu Tsugikuni, then?” the boy said. He looked about Michikatsu’s age. Perhaps a year or two younger. 

Michikatsu swallowed, frozen in place.

“Don’t tell anyone I was here, okay?” the boy said, placing a finger to Michikatsu’s lips. “No one can know.”

“Y…You’re stealing our posessions!” Michikatsu breathed, managing to speak.

The boy had piercing red eyes and they focused on Michikatsu like a cat observing it’s prey. And then he blinked and the look in his eye disappeared, replaced by a curious gaze. 

“You’re pretty,” he murmured. “I won’t take anything tonight, then. I have enough from yesterday. I’ll see you tomorrow, Michikatsu…” 

Then he was gone, disappearing into the night. The window was closed and Michikatsu let out a shaky breath. What the fuck had just happened. 

The next morning, Michikatsu was tired as hell having stayed up the rest of the night, his mind racing. 

His mother questioned him, as always, if he’d made any progress. 

“Did you see him? I checked the cameras and you stopped walking around after a bit. At one point, you were hiding in a corner of some sorts in your room. You stayed there for quite some time, and I had the video sped up. What happened?” she asked, handing him a bowl of fruits.

Michikatsu hesitated. He found himself not wanting to say anything. What if the boy never came back? 

No, that would be a good thing, right? But still…

“No, I got… tired. Sorry,” he apologized.

“You look tired. Did you not sleep during the day?”

“I did. But I guess it wasn’t enough,” he said, sighing.

“Your body is used to sleeping at night, it’s going off it’s usual schedule so your body is confused and you’re still tired even if you get the right amount of sleep,” Yoriichi said, sitting down at the table.

“Oh.” 

“Hm, why don’t you take a break from doing this, Michi’,” his mother said, handing Yoriichi a bowl. “You can focus on your job again. You have work today, no?”

Michikatsu nodded, picking up his phone that he’d left on the table the night before. “Mhm.”

“Then you can sleep tonight.”

“Alright. Thanks.”

She smiled at him then went back to the kitchen, talking to her husband about something.

“You did see something, didn’t you,” Yoriichi said, after their parents had left.

“What?” Michikatsu stared at him, his heart racing. “No, I didn’t,” he said quietly.

“Hm, sure. If you see them, just try to recount what they look like. It’s fine if you weren’t able to catch them, they’re clearly skilled,” Yoriichi assured him, misinterpreting his brother’s nervousness.

“I… Yeah, okay,” Michikatsu mumbled, spooning some of the fruit into his mouth.

The day flew by and soon night drew dark. Everyone filed to their bedrooms to sleep and Michikatsu, who had grown accostumed to the staying up, sat on his bed, completely awake.

He sighed, slumping against the pillows he’d stacked up on the head of his bed and stared at the cealing, his mind on the thief he’d met last night. Though, ‘met’ was a relative word. It would be more so… saw. Not necessarily acquaintences. Yet. Hopefully.

He groaned, bringing a hand up to his head and mussing his hair up, annoyed with himself.

Why was he like this?

He stayed awake for sometime, unable to fall asleep. It was a while before he found himself drifting off. 

He tried urging himself to stay awake then decided he’d rather not be tired in the morning. He had work, he would only make a mess of himself if he stayed up.

He fell asleep sometime around 1am, his dreams full of a boy with short black hair and red eyes.

Around early morning, 5am perhaps, he awoke. He was tired but instantly snapped out of his weariness when he noticed a figure in the far edge of his room, inching towards his desk.

“What…” he mumbled.

It was the boy again.

He looked up and their eyes met.

The boy put a finger to his own lips, making a shushing motion, and smiled mischeviously. Then, almost like an animal, he used a discarded box to jump higher up, making it appear as if it was a spring. In his hand was the same knife he’d put at Michikatsu’s throat the night before and he used it to smash the security camera that had been hidden on the cealing. 

Michikatsu flinched at the sound of breaking glass that pattered down the the floor.

The boy laughed and bounded over to the bed.

“You need to put up more cameras, one isn’t enough to catch ever part of the room. It’s why you’re so easy to steal from,” he said, pocketing his knife.

He sat down in front of Michikatsu who moved back instinctively.

“Hm, you slept tonight? Too tired to wait for me?” the boy asked teasingly.

“Who are you?” Michikatsu blurted out. He was curious. ‘Theif’ wasn’t exactly the name he could call the boy by (boy bi/j) forever.

“Me? I’m your biggest fan,” he said, winking exaggeratedly.

Michikatsu flushed. “Fuck off. I meant your name!”

He laughed. “Is my idol requesting to know my name?!” he said sarcastically.

“Stop it!”

“Fineeee… I’m Muzan. You can call me your number one fan,” Muzan said, grinning and leaning onto Michikatsu’s shoulder.

“If you’re my so-called ‘number-one fan,’ why do you steal from us?” Michikatsu asked, ignoring Muzan. 

“Hmm, you’re smart,” Muzan said, poking Michikatsu’s shoulder.

“No, your lies are just stupid.”

“You’re saying you’re dumb?” he asked.

“No! That’s not-” Michikatsu groaned. “Whatever. You never answered my question.”

“So I can make a shrine out of your clothes and cherish it forever—what do you think?! Your family has enough money, why not share it with people who don’t?” Muzan rolled his eyes and leaned back. “You’re cute, though, so I’ll blame it on your parents.”

“Stop saying that!” Michikatsu protested, his cheeks dusted pink.

“But I’m not lying,” Muzan said.

“I…” 

Muzan smiled coyly. “You’re easy to fluster, did you know that?” 

“Shut up…” Michikatsu mumbled, crossing his arms. Then, regaining his composure, he narrowed his eyes. “And stop stealing from us!”

Muzan tapped his chin. “Only cuz you asked, I’ll only take lesser-valuable things, then,” he said thoughtfully.

“Don’t take anything!”

“No can do, cutie. I’ll be off now. Oh! And you might want to think of an explanation for the smashed camera. Good luck,” Muzan said, pressing his lips quickly to Michikatsu’s before saluting him and practically flying out the window. “See you tomorrow!”

Michikatsu stared at the—now closed—window, a hand lifting to his lips where Muzan had kissed him. What… What the fuck had just happened?!
