ê« synopsis: Being Kim Taehyungâs assistant shouldâve been your first warning.
Heâs emotionally unpredictable, impossible to read, and has a habit of pulling people into his orbit without realizing how hard they fall.
One moment heâs distant for days.
The next heâs asking if youâve eaten, fixing your necklace clasp with quiet hands, and looking at you like he expects you to understand him better than anyone else.
Somewhere along the way, taking care of him stopped feeling like a job.
And started feeling like survival.

The first thing you noticed about Kim Taehyung is that he never walks into a room like he belongs there.
Which is strange considering every room bends around him anyway.
Staff members straighten when he passes. Managers lower their voices. Makeup artists hover nervously like theyâre handling something delicate and unpredictable.
But Taehyung himself looks detached from all of it.
Black hoodie. Messy dark hair tucked beneath a beanie. Large headphones around his neck. Expression unreadable.
He doesnât greet anyone when he enters the studio.
Just walk straight past them.
You glance down at the clipboard in your hands.
Schedule changes. Wardrobe confirmations. Dinner reservation moved to eight.
Again.
You were new to the scene but you werenât new to being an assistant to an idol.Â
Just an idol like Taehyung.Â
âDonât take it personally if he ignores you,â one of the stylists murmurs beside you. âHeâs weird at first.â
âAt first?â you whisper.
She snorts.
Before you can ask what that means, movement catches your attention.
Taehyung stopped walking.
Halfway across the studio floor, he turns slightly.
His eyes land on you.
Not casually either.
Directly.
Like he knew exactly where you were the moment he walked in.
The room continues moving around him. People talking. Racks rolling across the floor. Music playing softly overhead.
But for some reason it suddenly feels quiet.
You straighten awkwardly under the weight of his stare.
Thenâ
He walks toward you. Not the director. Not his manager.
You.
Your grip tightens around the clipboard as he stops in front of you.
Up close, heâs even harder to read.
Pretty in an unfair, almost disorienting way. But exhausted too. Like he hasnât slept properly in days. With a schedule like this, that wasnât hard to believe. His gaze flickers briefly to your company ID badge before returning to your face.
âYouâre new.â
It isnât a question.
You nod carefully. âAssistant coordinator.â
âHm.â
Thatâs it.
Just a low hum like heâs thinking about something you arenât part of yet.
Then unexpectedly:
âYou seem calm.â
Your brows lift slightly. â...Thank you?â
Another long stare.
And for one strange second, you get the unsettling feeling heâs trying to memorize you.
Then he reaches up, gently pulls one side of his headphones off, and says:
âCome with me today.â
Your mouth parts.
âIâ sorry?â
âMy assistant quit.â
He says it casually. Like commenting on the weather.
Behind you, someone nearly chokes.Â
âDid he just?â one makeup artist said, âShe has no idea what sheâs in for if she goes with him.â another said.Â
âYou can organize things, right?â he asks.
You blink. âI mean⊠yes, but Iâm assigned toââ
âYouâll do fine.â
And thenâ before you can properly respondâ
He turns and walks away expecting you to follow.
No explanation. No discussion. Just complete certainty.
The entire room goes silent.
One of the managers mutters:
âOh no.â he mumbled, âGo ahead and find another assistant. This one isnât going to last long.âÂ
~~~~~~~
The company building is nearly empty by the time Taehyung finally finishes reviewing edits.
Your eyes burn from staring at schedules all day.Â
Taehyung had you running around like a chicken with your head cut off. When he wanted something, he wanted it done right then and there. There were no negotiations. He had you look over 100s of pictures he took for a popular magazine in Korea, then he had you look over the interview questions without prior knowledge of what he wanted to answer and wanted to refuse, then to top it all off when one of the managers messed up his coffee order he expected you to go get a new one.Â
Now you were staring at 100s of emails that wanted Taehyung to either promote their product, become a brand ambassador or just come do an interview with them. It wouldnât be so bad if you didnât have to also review BTSâ schedules as well to make sure they donât clash with one another.Â
The members as a group and as individuals were in high demand. Reading these emails was like reading an encyclopedia. Â
Across the lounge, one of the managers gives you a sympathetic look while gathering her things.
âGood luck,â she whispers on her way out. You nod and wave before looking back down at your ipad.
You donât even have the energy to ask what that means.
The door shuts behind her.
Silence settles over the room.
Taehyung is sprawled across the couch with his phone balanced lazily against his chest, long legs stretched out beneath the low table.
For the first time all day, he looks still.
Not restless. Not distracted.
Just tired.
You glance at the clock.
11:43 PM.
Carefully, you close the ipad in your lap.
âI finished reorganizing tomorrowâs schedule,â you say quietly. âI also moved your fitting to the afternoon since the photographer requestedââ
âOkay.â
You blink.
Okay?
Thatâs the fastest heâs answered anything all day.
You stand slowly, gathering papers into neat stacks.
âWellâŠâ You hesitate awkwardly. âGoodnight, Taehyung-ssi.â
No response.
You look up.
Heâs already looking at you.
That same steady stare from earlier.
Unnerving. Focused.
Like heâs listening to something beyond your words.
Then:
âDid you eat today?â
Your fingers pause against the folders.
ââŠWhat?â
âYou forgot.â
You stare at him.
âHow would you know that?â
A small shrug.
âYou get quieter when youâre hungry.â
Taehyung sits up slowly.
âCome eat.â
You glance toward the clock again. âItâs almost midnight.â
âHm.â
âThatâs your response?â
Another shrug.
âI donât want to eat alone. Order some Japchae and get yourself whatever you want.âÂ
He said tossing his phone on the table before you before heading to the bathroom to freshen up.Â
You paused for a second before taking his phone into your hands and ordering some food.Â
The weight of the phone in your hand felt heavier than it should have.
Your thumb hovered over the screen, the bright display illuminating the confusion you had been suppressing all day. It was just Japchae and a side dishâa simple late-night mealâyet this sudden pivot from the demanding, unpredictable idol to a man concerned about your appetite felt like a trap you weren't prepared for.Â
All day, he had treated you like a machine, a tool to fix his schedule and fetch his coffee, but now he was looking at you with that unsettling, focused intensity, noticing the subtle shifts in your mood that even you hadn't fully acknowledged.
You navigated the app with practiced efficiency, your mind racing faster than your fingers.Â
Was this part of the "unpredictability" the files had warned you about? One moment he was the eccentric artist who expected you to read his mind, and the next, he was the only person in the building who realized you hadn't eaten since dawn. Very unlike you.Â
The sound of the bathroom door clicking open startled you. Taehyung emerged, his messy dark hair now damp at the edges and the beanie gone, making him look younger and even more vulnerable than before. He didn't say anything at first, just walked over and reclaimed his spot on the couch, watching you with that same unreadable expression.Â
"Ordered?" he asked, his voice a low vibration in the quiet lounge.
 You nodded, handing him back the phone while avoiding his gaze.Â
"Itâll be here in twenty minutes."
He hummedâthat same low, private soundâand for a fleeting second, the space between you felt less like an idol and an assistant and more like two people lost in the same late-night silence.
Like promised, the food arrived without any problems. As Taehyung pulled the food from the bags he realized it was very little for two people. So little they didnât even include a second pair of chopsticks.Â
âDid you get something for yourself?â he asked.Â
âI didnât want anything too heavy so I got some Baechuâ you said softly.Â
He didnât respond. Instead he just sat down.Â
He took the japchae and divided it evenly between you and him. He reached over and grabbed his bag, pulling out a cutlery set his parents gifted him and the members long ago that he became accustomed to carrying around.Â
âSitâÂ
It wasnât a question or a request.Â
You sat in front of the table on your knees while Taehyung sat with one leg propped up and his arm resting on his knee as he already started eating.Â
âEatâ he said in between chews before grabbing his phone to check the group chat he and the members shared.Â
âYou didnât have to share. I would have been okay until I got home-âÂ
âYou havenât eaten all day. Neither have I, letâs work on that.âÂ
That was the last thing he said before returning his attention back to his phone, fully expecting you to eat.
