Tae's chair was gone.
The war room desks belonged to whoever needed them. Six weeks into the project, the remaining Seniors returned to the same seats every night.
Jun noticed it before he set down his bag.
Three days earlier it had been tucked beneath the desk beside Jun's, one wheel catching whenever someone pulled it out. Now the desk held two stacks of printed exhibits, a box of charging cables, and a visitor badge someone had forgotten to return.
The project had adjusted quickly.
A yellow note was still stuck to Tae's monitor.
Regional assumptions need cleanup.
Jun dropped his backpack beside his own chair and opened the rollout model Tae had left behind.
Across the war room, Sojin divided the remaining work into four columns on the whiteboard. Her laptop sat perfectly square with the table. A notebook rested beside it, already half-filled with neat handwriting. Even in a borrowed war room, Sojin kept her desk exactly the way she wanted it.
Jun looked at his own space. Printouts disappeared beneath his keyboard. Marked-up slides hid three missing pens. An empty coffee cup had occupied the same corner long enough that he had started working around it instead of moving it.
He finally picked it up.
Across the table, Han noticed. Without a word, he leaned back until his head hung over the chair, one arm dangling toward the floor.
Jun looked over.
Han cracked one eye open long enough to confirm he had been seen. Jun smiled.
Satisfied, Han sat back up and resumed typing. No one reacted. Not even Sojin.
She capped the marker.
Jun's initials appeared beside the first and third columns.
I moved the regional pages to you.
I noticed.
Four names beneath work that had belonged to five people.
No one treated Jun like the new analyst anymore. The work came to him without anyone walking him through it.
Jun opened Tae's market-sizing file. The first tab was called `final_final_v2_REAL`.
Sojin glanced at the screen.
Jun opened the board deck.
Rows of comments waited along the right side of the screen. Some were assigned to Tae. Most had already been reassigned to Jun.
Not many.
Enough.
The war room carried the familiar rhythm of another late night. Fluorescent lights flattened every color into the same tired shade. Laptops hummed beneath the steady breath of the HVAC. Laughter drifted in from the elevators, then disappeared when the doors closed.
The door opened. Director Min stepped into the room with his laptop tucked beneath one arm. His eyes made a quick circuit around the table before settling on the whiteboard.
Min nodded. His attention moved to Jun's monitor.
Jun looked at the two columns beside his initials.
Min set a printed deck beside him. Blue ink covered the executive summary.
The model still assumes efficiency is what matters. That's what the client keeps saying, but it's not how they're acting.
Jun scanned the notes. The conclusion had not changed. Nearly everything supporting it had.
Min paused.
Jun's inbox refreshed.
He left as quietly as he had arrived.
For a moment, only the HVAC moved.
Then Sojin uncapped the marker and drew a line beneath the four columns.
Chairs rolled forward. Files opened.
By twelve-thirty, most of the floor was dark.
Yura completed the operating case, checked one final cell, and sent the file to Jun.
Three regions use the old integration sequence. Two use the new one. One uses both.
Han looked over his monitor.
Good. Three versions of the same assumption.
Yura checked the time but left her laptop open while Jun and Sojin worked out who would take the regional assumptions.
Jun reopened the model.
Sojin looked up from the implementation timeline.
It feeds the board logic.
She held his gaze for a second, then turned to the whiteboard. She erased Jun's initials from MARKET SIZING and replaced them with her own.
Yura waited until Sojin had the model open, then slipped her laptop into her bag.
She waved once on her way out. Then there were three.
Jun returned to the deck. The recommendation still worked mathematically. Every revision made the case cleaner. None made the client more likely to approve the acquisition.
Han appeared beside him and placed a coffee near the keyboard.
Jun took a sip.
Across the table, Sojin rebuilt Tae's regional assumptions one by one.
The door opened again. Min stopped in the doorway.
Another notification appeared.
Eleven new comments.
Jun read the first comment.
That was closer.
Min nodded and disappeared down the corridor.
Han waited until the footsteps faded, then matched Jun's flat delivery exactly.
Jun looked over.
Sojin continued typing.
The remaining comments did not shrink so much as change shape.
Jun corrected the board logic. That exposed a mismatch in the market model. Fixing the market model broke two appendix references. Han repaired the references while Sojin rebuilt the implementation sequence around the newest regional assumptions.
Then Sojin's cursor stopped.
Jun leaned across the table.
She turned her screen. A blank input sat between leadership approval and the first regional launch.
Jun searched Tae's handoff folder. Eight files. No notes. He opened the model. Tae always kept source assumptions in a hidden tab after the output sheets. Jun unhid it, then opened the email thread Min had forwarded.
Jun checked the source cell.
Nothing.
Tae had raised the issue twice. The first message had received no response. The second had become part of a longer thread about meeting availability.
Sojin read the thread.
Use eight.
Jun changed the assumption to eight. The rollout moved. The projected return weakened. The recommendation became harder to sell and easier to survive.
He saved the file.
The recommendation looked worse, but Jun trusted it more.
Sojin noticed him looking at the output.
Nothing yet.
He copied the change into the board deck and kept working.
Han closed his laptop and put on his backpack.
Jun glanced at the comment column.
Not many.
Enough.
Sojin saved her file and looked over the top of her monitor.
I can stay.
Jun checked the time. Her last useful train left soon. After that, getting home became two transfers and a taxi.
No. Send me the timeline and head back.
She studied him. Jun could see the calculation happening: remaining work, remaining time, his condition, her commute.
Jun looked at the deck. Eleven comments had become six.
I could.
Neither of them moved.
Her eyes moved to the clock. Then she started packing.
A zipper closed. A charger disappeared into her bag. Without conversation, every ordinary office sound seemed to travel farther across the room.
Her chair rolled back. She stopped beside Jun and set a packet of crackers on the desk.
Eat something.
She looked at him for another second.
The door clicked shut behind her.
Han watched it close before lifting his backpack onto one shoulder.
You know she would've stayed if you asked.
Jun was quiet.
Han nodded.
He headed for the elevators. The door closed.
This time it did not open again.
Jun looked back at the deck. An elevator chimed somewhere down the hall. When it faded, only the HVAC and the tapping of his keyboard remained.
He opened the crackers and kept working.
Jun cleared another comment. Then another.
The client did not need the most efficient integration plan. They needed one they could defend without leaving themselves trapped if the acquisition went badly.
Room to change course.
He opened the appendix to confirm the regional sequence.
Then he stopped.
That slide was not supposed to be there.
He scrolled back.
The appendix contained two versions of the same section. One was older. One was newer. Neither matched the references in the body of the deck.
Another slide. Then another.
Charts had shifted. Comments pointed to pages that no longer existed. Sections had been duplicated while others had disappeared so cleanly they looked deliberate.
Jun opened the version history.
Automatic resolution unavailable.
He opened the previous save.
Too old.
The next.
Already broken.
There was no version he could restore without sacrificing hours of work. He leaned back and rubbed both eyes. The fluorescent lights felt brighter than they had a minute earlier.
On the desk beside him, Tae's yellow note remained stuck to the monitor.
Regional assumptions need cleanup.
Jun looked toward the elevators. Sojin was halfway home. Han would probably already be asleep.
Calling everyone back wasn't an option.
Jun rolled himself back to the desk.
Okay.
Both hands settled on the keyboard.
One slide at a time.
Five minutes passed. Then ten.
Every repair uncovered another inconsistency underneath it. Jun traced one broken reference into another. His eyes lost the cursor. He found it again.
A faint prompt appeared near the edge of the monitor.
SYSTEM TRACE
Cognitive threshold exceeded.
Adaptive response available.
SYSTEM TRACE
ACCEPT?
[Y / N]
Jun stared at it.
There wasn't time to question what he was seeing. There was only time to finish the deck.
If this was exhaustion, tomorrow could deal with it.
If it wasn't... Tomorrow could deal with that too.
He reached toward the screen.
SYSTEM TRACE
[Y]
The prompt disappeared.
A cool sensation spread behind his eyes.
Not cold.
Clear.
Jun blinked once.
The monitor sharpened. The comments. The slide order. The conflicting versions.
The dependency chain.
His hands were already moving.
This time, he did not hesitate.
