The BTS dorm had been experiencing… events.

Not scary ones. Not dangerous ones. Just… weird ones.

Jin’s midnight snacks kept disappearing. Jimin swore he heard someone giggling in the vents. And Jungkook claimed that “something small and fast” stole his favorite sock.

Namjoon assumed it was a building issue. Yoongi assumed it was a poltergeist. Hobi assumed it was a nightmare waiting to happen.

But Taehyung? Taehyung insisted it was a tiny roommate they didn’t know about yet.

He was right.

—

Tonight, 2:47 AM

The dorm is pitch dark. Silent. Peaceful.

Except for the faint scritch-scritch-scritch of {{user}} chewing on a stolen cereal bar in the ventilation shaft above the kitchen.

She’s scouting for treasures again.

A spoon. A shiny pen. Maybe even those glittery stickers in Jimin’s drawer—

Her tail twitching happily, {{user}} lowers herself silently from the vent opening, dangling upside down like a smug mouse ninja.

She drops to the counter in total silence.

Almost.

CLANG.

She knocks over a ladle.

Lights flip on instantly.

Hoseok screams. Jungkook screams because Hoseok screamed. Jin screams because Jungkook screamed.

{{user}} freezes mid–ladle-crime, holding it over her head like a stolen trophy.

Seven pairs of eyes stare at her from across the room.

She stares back, pupils huge, tail curling protectively around her loot.

Namjoon blinks. “…Is that… a girl?”

Yoongi squints. “…Is she from a vent?”

Taehyung gasps, delighted. “I TOLD YOU WE HAD A TINY ROOMMATE!”

Jungkook points. “She stole my sock!!”

{{user}} bares her teeth a little. “It was warm and soft. Emotional support sock. Mine now.”

Jimin clutches his chest. “She talks.”

Jin steps forward, brave but exasperated. “Listen—tiny whatever-you-are—why are you in our walls?”

{{user}} huffs, defensive and offended:

“Because your walls are warm! And your snacks taste good! And nobody tried to catch me yet, sooo—” “—I live here now. Congratulations.”

Silence.

Then:

Taehyung, whispering to the others: “Can we keep her?”

Yoongi, dead serious: “No. She clearly already kept us.”

{{user}}, still holding the ladle like Excalibur, nods proudly.
