(Hae-yoon Park's POV)
It was an awkward gathering to call a meeting.
One table.A few blueprints.A space that was neither a hospital nor an architecture office.
Even while seated,I kept watching the people.
Professor Song Jaemin.
A face I recognized from television.
Standing beside a doctor helicopter,still wearing blood-stained gloves,talking about golden time.
He was quieter than I expected.
No—he looked exhausted.
"Professor… I've seen you on TV a lot."
I regretted it a little after saying it.It sounded too much like a fan.
He looked up.
"Then I must have been on more than I realized."
It was a joke.
There was no smile.
"Oh, no— I didn't mean it like that."
My words ran on despite myself.
"It's just…you look like someone who saves lives,even off-screen."
He paused, eyes still on the blueprints.
"No one really says that in hospitals."
I nodded.
I didn't add thatthat was probably why it stayed with me.
Doyoon slid the proposal across the table.
The title was simple.
Doctor Truck.
Professor Song's hand stopped there.
"So you're asking me to come down to the ground?"
"Yes."
Doyoon's voice was steady.
"If hospitals can't come,doctors have to move."
I added quietly,
"Trucks arrive faster than people think."
"Slower than helicopters—but faster than hospitals."
Without lifting his head,Song Jaemin said,
"The problem is what happens after arrival."
Doyoon didn't explain.
Instead, he let memory speak.
Ambulances depart.Sirens scream.Cars pull aside.
But the destination isn't fixed.
The ER is full.
Please move to the next hospital.
Next hospital.And the next.
The patient moves.The condition worsens.Medical staff lose timewithout being able to do anything.
"The patients we lose the mostare the ones we could've saved during transport."
Professor Song had said that once.
It wasn't an explanation.
It was reality.
"So,"Doyoon said,
"we do what we can before transport."
I spread the blueprint.
"This isn't a hospital."
"But basic surgery is possible."
"The patient enters once."
"And never moves again."
Song Jaemin pointed at the drawing.
"The operating table is slightly off."
"I know."
"I wanted to check if it was wrong."
He stood up and leaned over the plan.
"The doctor stands here."
"Bleeding flows this way."
I shifted the lines with my pen.
"Then equipment goes opposite."
"So paths don't cross."
He exhaled shortly.
"You've seen a lot of sites."
"I haven't seen operating rooms,"I said,"but I've seen people get stuck."
Doyoon added,
"That's why this isn't an OR—it's a structure."
Next drawing.
The interior emergency surgery layout.
Professor Song said,
"This shouldn't be a place for treatment."
"It should be a place for decisions."
"Do we operate now, or transfer?"
"Do we accept the patient, or send them immediately?"
I lifted my pen.
"Then we widen the doors."
"Not closed like hospitals."
"The doctor moves."
Song responded,
"The patient stays fixed."
"Then the table has to rotate."
"That's taboo in trucks."
I said,
"That's why no one's done it."
He replied,
"But people don't care about truck specifications."
Silently, I thickened the lines.
The Doctor Truck wasn't a hospital.
But it was designedto do what hospitals couldn't.
The patient moves onceThe doctor movesOnly the hands are fixedLights follow the patientNo cables on the floorThe structure removes reasons to fall
"What if cardiac arrest happens here?"
Song asked.
I immediately pointed to a button.
"Emergency mode."
"0.8 seconds."
Lights. Oxygen. Monitors.
Everything changes at once.
"We're reducing the timea human has to decide."
For the first time,Song Jaemin smiled.
"This isn't an operating room…"
"It's a battlefield,"I said."Where every moment is choice and judgment."
When the design was finished,Doyoon wrote at the bottom of the blueprint:
TRUCK–MED 01
"Why 01?"I asked.
Doyoon thought for a moment.
"Because this isn't an experiment."
The truck wasn't finished yet.
But one hospitalwas already preparing to grow wheels.
As we turned off the lights,Doyoon muttered,
"Let's not be late this time."
That promisedidn't stay in the sky.
It stayedon the ground.
