Mirae talked in her sleep.
Not the rambling, run-on sentences of her waking life. Fragments. Short, clipped syllables that came out between breaths — the verbal output of a system running background processes while the user interface was shut down. Jiwon woke at 5 AM to the sound of it, disoriented for three seconds about where he was (floor, concrete, cold, safe room, Wangsimni) before his brain reindexed and the world rearranged itself into the correct directory structure.
The cot creaked. Mirae shifted. And the fragments continued.
"...seven-four-two, index... no, reset... carrier alignment fault... query rejected, query rejected..."
He sat up slowly on the hard floor. His back ached from sleeping on concrete with only his jacket rolled under his head. The room was dark — no windows, no electricity, the butane stove's flame long since extinguished. The only input was audio: Mirae's breathing, Mirae's sleep-talking, the distant mechanical hum of the print shop next door starting its morning cycle.
"...perceptual thread unbound... user not found in registry... running diagnostic on node—"
The words weren't Korean. Or rather, they were Korean in grammar and vocabulary, but the content was wrong — technical, procedural, the language of system diagnostics. Carrier alignment fault. Query rejected. Perceptual thread unbound. These were phrases Jiwon had never heard spoken aloud, but their structure was familiar. They sounded like error logs. Like the output of a monitoring process reporting failures in real time.
He listened for four minutes. Counted seventeen distinct fragments. Wrote down the ones he could make out in his notebook by the light of his flashlight, keeping the beam angled away from the cot so it wouldn't wake her.
*carrier alignment fault*
*query rejected (x3)*
*perceptual thread unbound*
*user not found in registry*
*running diagnostic on node [unintelligible]*
*integration layer mismatch*
*null entry detected — flagging for review*
Then the fragments stopped. Mirae's breathing evened out, deepened, became the slow rhythm of genuine sleep rather than whatever half-state had been producing the diagnostic language. The cot stopped creaking.
Jiwon stared at his notebook. The phrases didn't match anything in his IT experience — they weren't TCP/IP errors, weren't database diagnostics, weren't any protocol he'd worked with. But they had the *structure* of system messages. The pattern of automated reporting: condition, response, escalation.
She was receiving System output in her sleep. Or her brain was generating language that mimicked System output. Or — and this was the hypothesis that made him grip the pen harder — the System was partially communicating with her, leaking diagnostic data through whatever channel her fourteen-minute [ERROR] had left open.
He filed it. Didn't label it as confirmed. Didn't assume. Just added a note at the bottom: *Mirae — sleep-talking matches System diagnostic patterns. Possible partial System access? NOT SHARED BY SUBJECT. Observe. Do not confront.*
The last line was important. If she was hiding this — and based on her deflection when he'd asked about unusual experiences at the playground, she was — then confronting her would break whatever fragile trust they'd built over one shared escape and one cup of instant coffee. He needed to let it surface on its own. Like a background process: don't force-quit it, just monitor the output.

Morning in the safe room was a logistics problem.
"Mirae is standing up now," she announced. "Mirae is walking toward the — where's the stove? Jiwon, where's the stove, because Mirae cannot see the stove and she cannot see you and she's going to step on something or someone and it's going to be really embarrassing for everyone."
"Stove is to your left. About two meters. The water jug is next to it on the floor."
"Thank you. Mirae is turning left. Mirae is walking. Mirae is — ow."
"What?"
"Table leg. Mirae found the table with her shin. Mirae is fine. Mirae's shin is not fine but Mirae is fine."
They developed a system over the next hour, partly by discussion and partly by collision. The room was small — four by five meters — but when you couldn't see the other person occupying it, even a small room became a minefield of potential contact. They established zones: the cot was Mirae's, the floor area near the door was Jiwon's. The stove and food supplies were neutral territory, accessed by announcement. Movement was narrated. "I'm getting water." "Mirae is going to the corner to pee in the bucket." "I'll face the other wall."
The bucket was the worst part. No bathroom. No plumbing in the room. Just a plastic bucket in the corner, left by the contact along with a roll of toilet paper and a bottle of hand sanitizer. Using it required announcing your intention, waiting for the other person to create auditory distance (humming worked — Mirae hummed parts of a song Jiwon didn't recognize, something with a jangling guitar line), and pretending the whole thing was normal because the alternative was acknowledging that two adults who'd met yesterday were sharing a bucket in a dark room and that was their life now.
"This is so messed up," Mirae said, washing her hands with sanitizer. "Like, Mirae could handle the invisibility. Mirae could handle the homelessness. Mirae could even handle the loneliness, kind of, mostly. But the bucket is where Mirae draws the line. The bucket is the thing that makes this real, you know? The bucket is the — what's the IT term for the thing that breaks the system?"
"Single point of failure."
"The bucket is the single point of failure for Mirae's dignity."
"I'll try to find a better setup. Maybe there's a bathroom in the building."
"Mirae would literally kill for a bathroom. Not like metaphorically. Mirae would commit actual violence."
---
After coffee (the second-best cup of instant coffee Jiwon had ever tasted, which said everything about his current quality-of-life baseline), he spread his notebook on the table and laid out everything.
The process was familiar — not comfortable, but familiar. Presenting data. Building a case. The same skill set he'd used in IT when a client's system crashed and needed a root cause analysis. Except the system was reality and the client was a woman he couldn't see who interrupted every third sentence.
He walked her through it. The Hapjeong leak. The contact's first message. The dead drop. The hospital infiltration. The paper-only records room and Directive 17-C. The twenty patients with temporary [ERROR] across three dungeon breaks.
"And then I found your file," he said.
"Mirae's file."
"Patient J-1547. Temporary [ERROR], fourteen-minute duration. Flagged by someone signed as Director of Cleanup Operations for continued monitoring under Protocol Seven."
"And Protocol Seven is..."
"I don't know. The note didn't define it. But the context was clear — if your status destabilizes again within six months of the Jamsil break, the Cleanup unit activates whatever Protocol Seven is. And based on what we know about the Cleanup unit's four previous detentions — zero releases."
Quiet. The specific quiet of a person absorbing information that reorganizes their understanding of their own situation. A schema update. The kind that required a restart.
"So Mirae is on a list." Her voice was flat. First person. The verbal tics stripped away, which meant the processing was happening deeper than the surface.
"You've been on a list since July."
"And the list has a timer."
"Three months left. Give or take."
"And when the timer runs out, the people with the dark coats and the chirping tablets come for Mirae and take her somewhere called 'the farm' and nobody ever sees her again, which, like — nobody sees her now, so what's the difference, right? That's — is that the joke? Is that the punchline? Mirae is already invisible and they still want to make her *more* invisible?"
He didn't answer. There wasn't an answer. She was right — the absurdity of it was the cruelest part. Being hunted for the crime of already being gone.
"Mirae has been invisible for three months," she said, and now the defiance was creeping in, replacing the flatness, her voice climbing back toward its natural register. "Three months. The dark coats came to Jamsil twice and they didn't find her. They had their tablets and their grid patterns and Mirae was sleeping thirty meters away and they walked right past her because that's what everyone does. Mirae is harder to catch than whatever their protocol thinks she is."
"They almost found you yesterday. They were at your bridge spot."
"Because *you* came stomping around Mirae's neighborhood for two days laying down traces like — like a, what do you call it—"
"I know. That was my fault."
"Like a very conspicuous ghost. The least stealthy invisible person in the history of invisible people."
"I said I know."
"Mirae is just saying."
"Noted."
She was quiet for a moment. Then: "What else is in the notebook?"
He told her about the gray suit man. The photographs from the contact. The mana device. Three dungeon breaks, three sites, the same figure in the same suit with the same device, positioned near the gate before each rupture.
"And you think this person is, like, making the gates open? On purpose? Causing the breaks?"
"That's the working hypothesis."
"Why would someone do that?"
"I don't know yet."
"Mirae might know why," she said. Then stopped. Caught herself. "I mean — Mirae has a theory. It's probably wrong. Mirae's theories are usually wrong, her statistics professor told her she had no intuition for probability, which was mean but also accurate—"
"What's the theory?"
"The temporary [ERROR] patients. The ones from the medical records. Twenty people across three breaks who went null for a few seconds or a few minutes. If this gray suit person is causing the breaks, and the breaks are causing the temporary [ERROR]s, then maybe... maybe the breaks are the point? Not the monsters. Not the casualties. The *erasure*. The breaks are how you make more Erased people."
Jiwon's pen stopped moving on the notebook page. He'd been writing while she talked — habit, compulsion, the IT worker's reflex to document everything — and now the pen was still because the thought was good. Better than good. It was the connection he'd been circling without making.
The dungeon breaks weren't attacks. They were a delivery mechanism. The gate ruptures were how the System's [ERROR] status was transmitted — through proximity to the mana event, through whatever the gray suit man's device did to the gate. The casualties were collateral damage. The real product was the Erased.
"That's not a bad theory," he said.
"Mirae literally just said she has no intuition for probability."
"Your statistics professor was wrong."

He left for Yongsan at noon. Mirae didn't want him to go — she didn't say so directly, but the way her sentences sped up when he announced his plan and the way she asked three times how long he'd be gone and the way she positioned herself near the door (he could hear her breathing, close, between him and the exit) communicated the message clearly enough.
"Three hours," he said. "Four at most. The electronics market is in Yongsan. I need a phone charger."
"Mirae will be here. In the dark. Alone. In a room with a bucket. For four hours."
"There's food. Coffee. The flashlight."
"Mirae can't see any of those things, Jiwon. Mirae is invisible. The flashlight is for *your* benefit."
He paused. She was right — the flashlight was useless to her. She navigated by touch and memory and the relentless internal monologue that mapped space through narration. She didn't need light. She needed another person in the room.
"I'll be back," he said. "I'll knock four times on the door when I return. Two fast, two slow. So you know it's me."
"That's a very IT-worker way to say 'I'll come back for you.'"
"I'm not saying that. I'm saying I'll knock four times."
"Mirae heard what she heard."
He left through the service entrance, into the alley, into the street. The absence of Mirae's voice was immediate and complete — one step through the door and the continuous audio stream cut out, and the silence was louder than it had been three days ago, before he'd found her, because now he knew what the alternative sounded like and the alternative was better.

Yongsan Electronics Market was a sprawl of stalls across four floors of a building that had been continuously reinventing itself since the 1980s — first as a legitimate electronics hub, then as a gray-market import bazaar, then as a tourist destination, and now, post-Awakening, as the last place in Seoul where you could buy hardware that wasn't System-integrated. The upper floors were where the old vendors operated — the ones who'd been selling pre-Awakening tech since before the word "Awakening" meant anything, who paid their rent in cash, and whose inventory included devices that the System's infrastructure didn't touch.
Stall 47, second floor. The vendor was a man in his sixties with reading glasses on a chain around his neck and a display case full of burner phones, analog cameras, shortwave radios, and components that Jiwon couldn't identify but that looked like they belonged in a museum of early computing. The man was eating a bowl of jjajangmyeon and watching a small portable TV that ran on an antenna, not a network connection.
Jiwon found the charger — a universal model with interchangeable tips, compatible with the ancient flip phone. He left 15,000 won on the counter next to the vendor's noodle bowl. The man didn't react. The money sat there, unnoticed. The vendor took another bite of jjajangmyeon and changed the TV channel.
On his way out, Jiwon passed stall 31. A repair bench, cluttered with tools and circuit boards and the disassembled skeletons of old phones. The motion-sensor light above the stall didn't activate as he passed — normal, expected, every System-connected sensor ignored him.
But it also didn't activate for the person standing at the repair bench.
Jiwon stopped. The bench had tools on it. A soldering iron, plugged in, its tip glowing orange. A circuit board held in a third-hand clamp. And the soldering iron was moving. Tilting down toward the circuit board, touching a specific point, holding for two seconds, lifting. A precise, practiced motion. The motion of someone who knew how to solder.
The soldering iron was being operated by no one.
Another Erased person. Right here, in the electronics market, working on a circuit board at a repair bench as if this were their job, as if they came here every day and soldered things and nobody noticed because nobody could notice.
Jiwon's feet wanted to stop. His investigative instinct wanted to approach, to speak, to make contact the way he'd made contact with Mirae. Another ghost. Another null entry. Right here.
He kept walking. Lesson learned. No trace flares. No concentrated search patterns. He noted the stall number — 31 — and the details (soldering, circuit repair, precision work suggesting experience) in his notebook and left the market by a different exit than he'd entered.
On the walk back to Wangsimni, taking an indirect route that zigzagged through three different neighborhoods to avoid creating a readable path, he thought about the soldering ghost. Another person the System had uninstalled. Another life continuing in the negative space of a connected world. How many of the contact's forty-three were doing exactly this — finding corners of the old world where analog infrastructure still functioned, carving out tiny, invisible existences in the gaps between the System's awareness?
Forty-three people. In a country of fifty-two million. A rounding error. A margin of loss so small it wouldn't show up in any statistical report.
But rounding errors compound. And margins of loss, if left unaddressed, eventually crash the system.

He knocked four times on the safe room door. Two fast, two slow.
The door opened from the inside. A hand — small, rough with paint — found his arm and pulled him through.
"Three hours and forty-seven minutes," Mirae said. "Mirae counted. Mirae has been counting since you left because what else is Mirae going to do in a dark room with a bucket, play cards? So Mirae counted. Three hours and forty-seven minutes."
"I said four at most."
"Mirae is not complaining about the time. Mirae is complaining about the counting. Counting is the worst possible activity for a person with Mirae's brain. Mirae's brain does not do well with repetitive sequential tasks, Mirae's brain wants to jump ahead and circle back and go sideways and counting is like, it's like putting Mirae's brain in a cage—"
"I got the charger."
"Oh thank god. Not for the charger, for the subject change."
He plugged the burner phone into the charger, connected to the portable stove's USB output (the stove had a charging port — a feature that explained why the contact had chosen this particular model). The phone's screen lit up. Green-on-black, the fossil glow of technology from another era.
One message waiting. Text, from the contact's number.
He opened it.
*Situation changed. Cleanup expanded operations — three sweep teams active in Seoul as of yesterday, up from one. Sweep radius increased to 500m around all known dungeon break sites. New directive from their command: locate and detain all null entries within 30 days.*
*Do not leave your current location for 72 hours. The Wangsimni safe room is clean — no traces on record, no previous Erased have used it.*
*One more thing. The Gangnam medical center conducted an internal security audit two days ago. They found signs of unauthorized access in their administrative wing — bent ventilation grille, displaced ceiling tiles, scuff marks on office 302's desk. Records room B has been emptied and all files transferred to Association HQ basement level 3. Restricted access. Physical key held by Director Chae Yoonseo personally.*
*The medical center has reported the breach to Cleanup. They're connecting it to the Hapjeong leak. They now believe the same individual who leaked the dungeon break files also accessed the System-anomalous case records.*
*They're right, of course. Isn't it inconvenient when the people hunting you are competent?*
Jiwon read the message twice. Then a third time.
They knew. The hospital break-in, which he'd thought was clean — the careful entry through the ceiling, the copied files, the returned key, the replaced step stool — had left traces after all. Physical traces. The bent grille. The ceiling tiles. The scuff on the desk. Mundane evidence that no amount of System invisibility could erase because it had nothing to do with the System. It was just a man crawling through a building, leaving marks on metal and dust on surfaces and the ordinary physical residue of a body moving through space.
His invisibility protected him from perception. It did not protect him from forensics.
"Jiwon?" Mirae's voice, from the cot. "Your breathing changed. What does the message say?"
He told her. All of it. The expanded Cleanup operations, the thirty-day directive, the seventy-two-hour lockdown, the medical center breach.
"So they know someone broke in and stole files and they think it's the same person who leaked the Hapjeong stuff and they're now looking harder than before. Because of you."
"Because of me."
"And now Mirae is locked in a room with the person the Association is actively hunting, which makes this room a target, which means Mirae traded being alone and safe for being accompanied and in danger."
"That's accurate."
He waited for the anger. For the accusation, the recrimination, the entirely justified observation that he'd made her situation worse by finding her. The silence stretched — three seconds, five, eight — and then Mirae said something he didn't expect.
"Good."
"Good?"
"Being alone and safe is just dying slowly, Jiwon. Mirae already tried that. Three months of it. Being accompanied and in danger is at least — it's at least a different kind of dying, you know? At least this way there's someone to hear it when the bucket tips over."
A sound between a laugh and a cough. His, not hers.
"Seventy-two hours," she said. "That's three days. Three days in a room with a bucket and a stove and instant coffee and a person Mirae can't see. Cool. Cool, cool, cool. Mirae has definitely had worse weekends. Like that time her roommate's boyfriend stayed over for a whole week and he kept leaving the bathroom door open, that was objectively worse than this."
"I doubt that."
"You didn't see the bathroom door situation, Jiwon. You don't get to judge."
Mirae started humming — the song with the jangling guitar. Jiwon opened his notebook to a fresh page, wrote *DAY 1 — LOCKDOWN*, and began cataloging what he knew, what he didn't know, and the gap between the two.
