My Boss Sunghoon

 

A Different Kind Of Assistant

The practice room was louder than expected.

Music blasted through the speakers, bass vibrating through the floor, sharp counts echoing off the mirrored walls.

“Five, six, seven again!”

The choreographer clapped sharply.

And at the center of it all—

Sunghoon.

His movements were precise. Controlled. Effortless in a way that didn’t look human.

Every step hit perfectly on beat.

Every turn clean.

Every expression restrained but powerful.

But even perfection had a cost.

⸻

You stood near the entrance, tablet in hand, observing.

Timing.

Spacing.

Break intervals.

You weren’t just watching the dance.

You were watching him.

The slight delay when he shifted weight to his right leg.

The near-invisible tension in his shoulders.

The way his jaw tightened just a little after each full run.

Most people wouldn’t notice.

But you did.

⸻

“Again!”

The music restarted.

Sunghoon moved—

Sharp.

Fast.

And then—

A slip.

Barely noticeable.

But enough.

The music cut instantly.

The room went silent.

“…We’re wasting time,” the choreographer muttered, clearly irritated.

Sunghoon didn’t respond.

He just stood there, chest rising and falling once controlled.

Too controlled.

“I said again,” the choreographer added, impatience creeping in.

You glanced at the clock.

11:28 AM.

Three full run-throughs without a proper break.

And—

If your memory was right—

His physical therapy session had been yesterday.

Meaning today…

He shouldn’t be pushing this hard.

⸻

Before anyone could restart the music—

“Five-minute break.”

Your voice cut cleanly across the room.

Every head turned.

The choreographer frowned.

“Who—”

“I adjusted the schedule,” you continued calmly, stepping forward. “You’re now five minutes ahead. A short break won’t affect the overall timing.”

“That’s not your call—”

“It is,” you replied, tone steady. “Unless you’d like to explain to management why today’s recording gets delayed instead.”

A pause.

Tension.

Then—

A quiet scoff.

“…Five minutes.”

The room slowly relaxed.

Staff moved. Water bottles were grabbed. Music lowered.

Crisis temporarily avoided.

⸻

Sunghoon walked past you without a word.

Straight to the corner.

You followed, holding out the bottle.

“Room temperature,” you said.

He took it.

Drank.

Silently.

Then—

“…You’re interfering.”

His voice was low.

Not angry.

But not approving either.

“I’m preventing inefficiency,” you replied.

A beat.

He looked at you.

Really looked this time.

“Or are you assuming things you don’t understand?”

You didn’t hesitate.

“You’re favoring your right side.”

Silence.

“You’ve repeated the same section six times. Your landing is starting to shift by a few centimeters. If it gets worse, it affects synchronization and the recording schedule.”

Another pause.

Longer this time.

“…And?” he asked.

“You won’t say you need a break,” you said simply. “So I said it for you.”

⸻

For a moment—

Nothing.

The noise of the room faded into the background.

Sunghoon’s gaze didn’t leave yours.

Sharp.

Searching.

Then—

“…You’re observant.”

Not praise.

But not dismissal either.

You didn’t respond.

⸻

Across the room, a staff member rushed in.

“Sunghoon, the recording studio just called they’re asking if you can arrive earlier. There’s an issue with the setup.”

You stepped in before he could answer.

“We’ll still arrive on time,” you said. “Please ask them to prepare Studio B as backup. And confirm the engineer is ready to start immediately at 1:30.”

The staff blinked.

“…Right. Okay.”

They hurried off.

⸻

Sunghoon tilted his head slightly.

“…You already handled it?”

“I told you,” you said, meeting his gaze. “You won’t be late.”

A pause.

Then—

That same faint smile from earlier.

Barely there.

“…We’ll see.”
