Seorin stopped before putting her finger beside her signature.
The rectangle on the paper was no bigger than a fingernail. Its border cut through the final stroke of her name. A short black speck lay beneath it. With the naked eye, she could not distinguish a drop of ink from dust caught during copying.
“I didn’t sign this sheet myself.”
The site staff member kept filming.
“Have you used the same signature elsewhere?”
“Yes. I don’t yet know where this came from.”
Finding a signature dated tomorrow was different from finding its original. She pointed first to the empty fields. No inspection result. No finishing time. Only the signature had arrived early.
Nam Gijun rested his hand on the desk’s edge.
“The contractor sent the form. Filled in the name too. I left it here for you to check when you came tomorrow.”
“Exactly as you received it?”
“I only printed it.”
“Who sent it?”
Before answering, he took out his phone. The staff member did not stop his hand, but first asked whether he was willing to show the received material related to this document. After a hesitation, Gijun laid the screen faceup on the desk.
A group work chat. Seorin was not a member.
At 16:12, a file called Safety Confirmation Form had arrived. The sender’s displayed name was Sero Facilities Management, Business Support. The name alone did not establish the person who had sent it.
Seorin opened her saved work notice. Her company had sent it to the site yesterday afternoon. Today’s visiting time, the inspection’s scope, the company contact. No signature field.
“The notice on the wall has my name, but no signature.”
“Then they got it somewhere else,” Gijun said.
“We need to establish where somewhere else is.”
Without looking at him, she wrote down the two document titles. The same person’s name did not make them the same file. Work Notice. Final Safety Confirmation. One announced a visit. The other could make a job look finished.
Shoes stopped outside the office.
A woman read the access restriction at the threshold. Raindrops dotted the sleeve of her dark gray jacket. She introduced herself before entering.
“Mo Eungyeong, Sero Facilities Management. I’m the project manager. The caretaker called me.”
Seorin had seen the name in the commissioning paperwork. Site contact, rather than approving officer.
Eungyeong nodded to Doun, then offered Seorin her business card.
“This must have been a shock. I understand the resident got out safely. Can tomorrow’s final confirmation go ahead, then?”
A gentle voice. The question saved for last.
“There are areas we haven’t inspected today. Someone was trapped in a connecting section missing from the plans.”
“An old drawing seems to have got mixed in. I’ll send the revised version.”
“Please include when that revision was made.”
Eungyeong’s hand paused over her cards, then lowered into her bag. Seorin put the card she had received into her document pouch. She did not record a pause as an answer to what someone was thinking.
The staff member explained the boundaries. Only designated people could enter the office to check records. The connecting section was being preserved after the rescue. Other clearance workers had to wait outside.
Eungyeong nodded at once.
“We’ll cooperate. I’d prefer fewer of our staff going in too. Everyone’s responsibilities need to be clear.”
She looked at the paper Seorin had opened.
Tomorrow’s safety confirmation.
“That’s a draft.”
“The draft has my signature.”
“Someone may have added it from previously submitted material while formatting the form. We get confirmation before final submission.”
“Have you established who took it, and from which material?”
“I’ll find out.”
Neither admission nor denial. Seorin wrote the words as they stood. Described as a draft. Source unconfirmed.
Doun drew the job sheet from his car closer to his chest. She noticed, but added no question. If everyone began explaining at once, they would lose track of which document each answer concerned.
She told the staff member she would call her company. There was no need to let everyone hear a private conversation. She explained that she wanted to check the list of submitted documents carrying her signature.
The duty officer answered by asking whether the visit was over.
“Not yet. Tomorrow’s final confirmation already has my signature on it.”
A chair moved at the other end.
“We only put your name on today’s notice.”
“I have that file too. Have we sent anything recently with my signature image attached? Just send me the list of files first.”
The officer checked her submission history in the company archive. No request to rummage through a screen or enter someone else’s account was needed. A few minutes later, three document titles and their sending dates arrived.
One was the Preliminary Structural Risk Review for Eundam Residence.
Written last week. Some areas not entered. Further site inspection required.
She remembered. Unable to confirm safety from the plans alone, she had written that last sentence herself.
That document carried her signature too.
“Could I have the original file? And the limits of company approval if it needs to be shared outside?”
“It’s your submission. I’ll send you a viewing copy with the other staff information covered.”
Outside the office, low voices continued. Two clearance workers had come to collect equipment and were waiting. Seorin did not write down their names for them. The person controlling access checked their purpose and where they would wait.
That small pause kept anyone from walking toward the stairs as a matter of course.
She enlarged the viewing copy. A short black speck lay at the end of her signature. Beside it ran a faint gray line, a fold scanned with the paper.
Tomorrow’s confirmation had the black speck, but no gray line.
She could say they resembled each other. Saying one had been cropped from the other required more comparison. She began matching the images’ magnification, then stopped. She was comparing screen size with paper size.
“It looks like the same blemish. We need a proper comparison of the originals.”
The staff member nodded.
Eungyeong did not move closer to look at Seorin’s phone.
“We’ll check our retained submission and send it too. If the person responsible has gone home, it may be morning.”
“Please ask them not to alter the existing file before sending it. Any revision should be separate.”
“I didn’t mean we’d delete it.”
“Yes. I’m asking for it to be preserved.”
The words stayed in the room. Seorin left the silence alone. Questioning someone who promised cooperation was not always comfortable. Still, courtesy could not settle a document signed today by someone who had not yet made tomorrow’s visit.
Channel 4 now showed an empty passage.
Without a person, the picture looked safe. But it had emptied only thirteen minutes after Haeun came out. This empty space did not prove the present either.
Seorin asked permission to put a note beside the monitor. The staff member agreed.
CHANNEL 4. CONNECTING SERVICE PASSAGE. CONFIRMED DELAY: 780 SECONDS.
The black handwriting went immediately below the printed Room 214 sticker, without covering it. She added the error instead of peeling away the old label, so anyone arriving later could see what had changed.
“Best to correct that sort of thing quickly,” Gijun said.
Even while looking at the new note, he stood with his back to the key board.
Seorin sent her company an interim report comparing the submitted plan with the site measurements. A drawing marking the connecting section NO ACCESS could not support a completed residual hazard inspection. Today’s conclusion was short.
FURTHER INSPECTION REQUIRED. SAFETY CONFIRMATION INCOMPLETE.
After sending it, she checked the transmission time beside her name. This time, it was an endorsement she knew she had made.
The staff member made a preservation copy of tomorrow’s form. The original stayed beneath the office desk’s transparent cover. A record identified who had photographed which pages. Seorin would take only an authorized copy.
Eungyeong called Business Support. Seorin did not try to hear the whole conversation. Afterward, Eungyeong herself confirmed that she had requested preservation of all files sent so far.
“I’ll put tomorrow’s dismantling crew on standby for now. The final schedule needs discussion with the commissioning officer.”
“Please send a copy of the standby notice too.”
“I will.”
Seorin dated the copy’s envelope and folded the opening. Instead of FINAL, she wrote COPY CHECKED IN THE SITE OFFICE. She left the same explanation for whoever received it, so possession would not be mistaken for her confirmation of its contents.
Demolition had not been officially suspended. She put that limitation in her notes. Tonight’s restricted access and the contractor’s temporary standby did not decide the building’s future.
She asked when the form had been printed. Gijun pointed to a thin stack beside the printer. All the pages faced the same way, but the notice on top and confirmation below had different margins. She could not assume they had been produced together.
“You received it this afternoon, then printed it?”
“Yes. I don’t remember the exact time.”
Seorin wrote 16:12 as the printing time and immediately crossed it out. That was the file’s arrival time. Put numbers in small boxes, and different events easily became the same event.
The staff member asked why she had corrected it. After she explained, he distinguished receipt from printing in his own record. At least her mistake had not become someone else’s certainty.
Vehicle lights swept the office window. Her reflected face briefly overlapped tomorrow’s date. She left the paper uncovered. It took more people than she had expected to record that an unfinished job remained unfinished.
Doun opened his job sheet.
“I think you should look at mine now too.”
He pointed to an instruction from three months earlier, a different kind of document from the preliminary review she had just found. A small contract number appeared in blue ink below the equipment number.
Seorin reopened the photograph of the relay cabinet’s management label.
The same device. Every digit matched.
The contract number on its label was different.
“Was there another contract?”
Doun held the paper’s edge without speaking. This time, waiting did not make her question disappear.
A contractor’s vehicle started outside. A low vibration came through the window. Only when it faded did he look at her.
“I haven’t told you all the work I did.”
