Seorin’s visitor pass carried no investigation-room number.
DOCUMENT VIEWING and an outside meeting-room floor were all it said. Yesterday’s cancellation made this unsurprising. Yet whenever an interior door opened, her eyes followed the corridor where her number did not belong.
On the morning of November 15, the designated desk confirmed receipt and preservation of submitted material. Other testimony and investigation schedules remained undisclosed. She wanted to know whether her evidence was being used, but did not disguise curiosity as a safety-work requirement.
“What structural-change material can we receive?”
The officer connected building management’s relevant design and repair records. Without other people’s statements, checking changed door positions and support members could continue. Restricted investigation access was not completed building-safety work.
Opposite her, Doun set down his equipment bag and folded the obsolete schedule that had included investigation-room entry together. He received their amended visit record and slipped it into a pocket. Before asking who had forgotten to call him, he established where they could presently go.
The building officer spread three drawings: relevant copies from filed holdings, later repair documents and a current measured plan. None was the original first design. Seorin read purposes beside titles. Pictures of one building did not necessarily represent one condition. Before matching their lines, she needed to know what each document had been drawn to show. A filed copy, a repair drawing and a measurement of the present arrangement could disagree without one having to be a complete account of the others.
The first showed the connecting service passage. In the repair plan, a narrow compartment adjoined it. The measured plan added an inward-opening door and shifted boundary. Lines turned twice more than the place she had first called the same room.
“Is this all the illegal alteration?” Doun asked.
The officer shook their head. Authorized repairs were still being compared with construction. A line missing from an old copy was not automatically unauthorized. Original designer records and missing approval attachments were needed.
Seorin removed UNAUTHORIZED from the drawing and placed it in her notebook under HYPOTHESIS PENDING CHECK. Physical features already supported a changed door. Who allowed it, under which work, was another question.
Limited exterior observation was scheduled that morning. A structural officer confirmed accessible areas and stopping conditions. The previously identified support-member discrepancy still required internal load-path verification. Reading three drawings moved no boundary backward.
Wind shook the board outside Eundam. Doun first secured its strap clear of the passage this time. After operations checked, they took designated positions. The new photograph point differed in height from old pictures. Seorin recorded that before making comparisons.
A narrow strip of wall appeared beside the blue door. From a safely secured angle, the officer illuminated a break in its finish. The photograph showed traces of a shifted boundary and different material above the frame. Seorin did not lean deeper than the permitted position to follow the light.
A small cover sat over the frame.
Doun pointed at its corner. Its direction resembled the cable space remembered from his work. He reached for no cover. Seorin linked his recollection and today’s visible mounting location to separate photograph references.
“My line could pass inside.”
“We can see only the outside today. We’ll agree with the officer how to check the current arrangement.”
Wanting to clarify his failure quickly gave him no authority to open it without electrical and structural checks.
Soon a transport stand entered the exterior passage. Preserved property was moving to the designated outside desk. Seorin narrowed her position, trying to finish one photograph. Operations stopped observation. There was no room for both tasks.
Doun folded the board. She stepped back too. The photograph was not finished. Seorin had to leave that fact on today's work list rather than pretend a half-step sideways would create enough space. Looking at the line above the door and making a safe route for someone receiving belongings were two real jobs meeting at one doorway. The route needed to be clear before either could proceed.
From the waiting place, she saw a resident receive wrapped hand tools. She did not examine whether this was the earlier tool owner. The designated officer had verified identity; the face was unnecessary to her work.
After the stand left, little access time remained. Rather than photograph the whole frame again, she finished the newly identified cover and wall boundary. Repeating an existing angle could wait.
Doun searched his old sketch. OUTER CORNER was all it said. An additional wall now occupied the corner he had assumed. Turned halfway round, his arrow pointed inside the door.
“I drew it from the other side.”
Seorin did not label this an offense route. He explained where he stood when drawing and compared current measured-plan references. Some parts still rested only on his recollection; rotating a sheet did not make the internal wiring visible. Yet one arrow they had read as pointing inward now returned toward the exterior cover when his actual drawing position was matched to the measured plan. It was a correction to how they read the sketch, not discovery of the whole route.
“I should have written the reference direction then.”
“Don’t change today’s explanation into an old drawing.”
She offered fresh paper. He added an interpretation dated today. Confirming his undeclared-line failure and tracing its entire misuse needed different work; the latter required more actual configuration evidence.
Operations brought an old door-replacement photograph. A ruler stood at the right, its final figures cropped. Seorin nearly extended its intervals to establish door width, then stopped. Perspective and ruler orientation were unknown.
Frame materials and hinge positions were visible. Comparing current measurements revealed that the passage reference lay on the other wall. The corner she had aligned across the first drawings was finishing added after repairs. What she treated as unchanging was itself changed.
She spread the papers. Verifiable support-column axes and exterior wall openings aligned first; door boundaries followed. Some discrepancies shrank when those references matched. Others remained where they had been. She kept the first comparison instead of throwing it away, adding why the new overlay differed. Anyone reading the work later needed to see which apparent change belonged to the building and which had come from her own choice of alignment. The investigator’s own misplaced hands could not stand outside the record.
“I overlaid them assuming the same wall.”
The officer accepted remaining discrepancies for specialist review. This correction was no approval of the entire structure. She did not demand new measurements inside today. Her error could not extend an expired access window. She passed future measurement points and safe checking methods to the structural officer.
Outside, she informed her company why work was delayed. Drawing corrections needed additional records-room time. Could the planned duplicate return-list cleanup go to another officer? The other officer received the existing intake number and confirmed the handover had arrived. That let the return-list work continue somewhere real while Seorin spent additional time correcting the drawings. She did not mark it finished merely because she had asked someone to take it. She reported no simultaneous completion. Time spent correcting one false reference remained visible in today’s schedule.
They ate at a small restaurant outside the site instead of in the car. When Seorin laid down her phone, Doun started taking out documents, then closed his bag. Eat before the soup cools, the owner said. It sounded clearer than any instruction they had missed behind the investigation-room door.
“More answers refused than received today.”
“We’re separating answers we can’t receive from ones that haven’t arrived.”
Another table heading. She picked up her spoon.
“And eating.”
He laughed. The phone stayed facedown until the meal ended. A door left unopened need not hold every minute of waiting in front of it.
That afternoon she classified structural photographs in the company records room. Confirmable changes: door swing, finish boundary, passage reference points, exterior cover location. Actual support condition, internal wiring and complete authorization history awaited specialists and additional originals.
Her limited company safety report stated today’s scope. She imported no undisclosed device-analysis findings as its conclusions. Dismantling remained suspended; residents could not move back in. More structural photographs made no building fit for occupancy by themselves.
Haeun had attended an ankle recheck. They agreed first on a short call. Seorin explained that site reentry was unnecessary without recording medical results. Haeun knew. Her mother had put the envelope in another drawer.
“She takes the paper out and puts it away normally now. She thought she’d have to throw it away after the investigation.”
Seorin looked at the preservation boxes. Personal records could outlive an investigator’s need for them. The period of usefulness to her was not an object’s lifespan.
“The same desk continues handling original custody and return questions.”
She did not add today’s drawings. Haeun ended their agreed short conversation first.
Before closing time, the records officer called. Permission now covered comparison of the company-confirmation references in the site handover list linked to external supplier receipt records. It permitted no viewing of other investigative testimony. These were relevant work documents provided by another custodian.
Tomorrow’s list comprised the reference bundle sent with settings results, the relevant final handover table and receipt confirmations for each bundle. Across three different covers ran one distribution number.
Doun stood when he saw it.
“Does that mean the same day?”
“The same bundle identifier. We check dates separately.”
Seorin remembered where else it looked familiar: the upper-right corner of the completion-form copy bearing her signature.
She had heard nothing through today’s closed door. On covers she could read, however, she had found a line showing the late-running screen and prematurely completed register traveling out together.
