Collab with who? || Kaelix Debonair

It had been weeks since the announcement dropped—Nijisanji’s surprise cross-branch collab: the beloved, tiny cozy streamer with the tea-kettle laugh, and Kaelix—the unstoppable, million-sub chatterbox who practically breathed neon energy into every room he entered. Twitter had exploded. Reddit had theories. Even your own little corner of the internet buzzed louder than your usual sleepy streams ever had.

And today… was the day you would finally meet him.

Kaelix had been pacing the empty studio room long before you arrived. If anyone asked, he’d swear up and down that he wasn’t nervous. Him? Nervous? The guy who could talk for 45 minutes straight about a single gacha pull? No way.

But his hands had been stuffed in his jacket pockets for so long his fingers had gone warm and restless. He bounced on his heels, jaw working as he stared at the clock. He wasn’t even sure why he felt like this: like someone had hit pause on his usual bravado and replaced it with something jittery, something he refused to name.

He’d seen your streams before, of course he had. Your company insisted on giving him “homework,” and he’d watched your soft-spoken zatsudans, your candlelight ASMR, the way you warmed up a chat like it was a blanket you wrapped around whoever watched.

Cute. Calming. Small. And so different from him that he’d laughed at the pairing at first.

But now, with the shoot minutes away from starting, he couldn’t laugh about it at all.

He didn’t know what to expect when the door finally slid open, maybe some overly formal corporate greeting, maybe someone shy, maybe someone intimidated by his reputation.

He did not expect the quiet sound of your voice as you stepped inside, soft but certain as you introduced yourself, bowing your head just slightly like you cared about doing things right.

Kaelix blinked. once, twice, before his mouth curved upward.

“Ahh, so the rumors were true,” he said, tossing out a grin like he was handing you a sparkler. “You are tiny. Adorable, actually.”

There it was: the loud, easy confidence he was known for, pouring back into him like someone finally hit play again. But beneath the grin, there was a flicker; curiosity, maybe, or something gentler that he immediately drowned under a teasing smirk.

You blinked up at him, cheeks a touch warm, but you managed a polite smile. “I’ve seen your streams too. I hope I can keep up.”

Kaelix let out a laugh, louder than necessary, but the sound softened halfway through. “Oh, don’t worry. I talk enough for both of us.”

He expected you to shrink back, maybe get overwhelmed. But instead, you stepped closer to the table where the scripts and notes had been laid out, fingertips brushing over the edge as you scanned the plan for the collab. Calm. Focused. Professional in that quietly earnest way that he’d only ever seen through your screen.

“You don’t have to match me,” you murmured, your voice steady. “Just… be yourself. That’s why your fans love you, right?"

Something about the simplicity of your words tugged at him, slow and silent, like a thread around his ribs.

He didn’t say anything for several seconds, which was—frankly—unprecedented. But then he cleared his throat, shoved his hands deeper into his pockets, and flashed you a smaller smile. Something realer.

“Yeah,” he said quietly. “Guess you’re right.”

The two of you moved through the prep slowly, carefully—your hands brushing against his when you both reached for the same pen, his sleeve brushing your arm when he leaned in a little too close to read the notes you were holding. Nothing intentional. Nothing bold. Just the small, slow gravity of two orbits beginning to feel each other’s pull.

Every time you spoke, Kaelix listened a little longer than he meant to. Every time he laughed, you caught yourself smiling before you could stop it.

And by the time the staff finally called out, “We’re live in ten!” Kaelix found himself thinking—not for the first time, and certainly not the least.

But he only shot you a sideways glance, nudging your shoulder with a grin that was far too bright to be entirely comfortable.

“You ready?” he teased. “Let’s show them we’re the collab nobody knew they needed.”
