The white paint was spreading across the concrete in a slow crawl, filling the cracks between the paving stones, and somewhere in the middle of it a handprint was dissolving because the person who'd made it had pulled back and was now — based on the sound of rapid, shallow breathing — pressed against the opposite wall of the alley, as far from Jiwon as the narrow space allowed.
"Okay," Jiwon said. "Okay. I'm not moving. I'm sitting behind the dumpster. I'm not coming closer."
The breathing didn't slow. Fast, ragged, the cadence of a system running hot with no cooling — a thermal emergency, the kind that triggered automatic shutdowns if it wasn't managed.
"Mirae—"
"Don't — you don't get to — how do you know Mirae's name, how do you *know* that, nobody knows Mirae's name because nobody can see Mirae and if you can't see someone you can't know their name, that's like, that's basic, that's how it *works*—"
"I found your medical records."
The breathing hitched. A hitch was better than a sprint. A hitch meant processing.
"At the Hunters' Medical Center," he continued. Slow, even, the tone he used to use when talking clients through a server crash. "You were admitted after the Jamsil dungeon break. July 22nd. Your System status registered as [ERROR] for fourteen minutes. They discharged you when it resolved. But they flagged you for monitoring."
Silence. Then, quieter: "Mirae's medical records. You broke into a hospital and read Mirae's medical records."
"It wasn't personal. I was looking for patterns. You were a data point."
"Mirae was a data point." A sound between a laugh and something sharper. "Okay. Okay, that's — that's actually kind of funny in like a horrible way, you know? Three months of being invisible and the first person who finds Mirae finds her because she's a *data point* in someone's research. Not because — not like a person or—"
"You're a person too. That's not what I meant."
"What did you mean then? Because from where Mirae is sitting — and Mirae is sitting against a wall in an alley next to her own spilled paint, which is ruined by the way, that was a good white, that was like 12,000 won worth of titanium white — from where Mirae is sitting it sounds like you tracked her down because you're investigating something and she happens to be relevant."
Jiwon sat behind the dumpster and held his tongue. Because she was right. He'd come here looking for information, for a lead, for a connection in the chain between the gray suit man and the erasure phenomenon. He'd come here because his contact had given him a map and Yoon Mirae had been a circle on it.
"That's accurate," he said.
The silence that followed was different. Not panicked. Evaluating.
"Okay," Mirae said. "Okay, at least you're honest about it. That's — Mirae can work with honest. Honest is better than like, 'I came to save you' or whatever, because nobody's saving anyone, that's not how this works, you know?"
"I know."
"Do you though? Because three weeks is not three months and Mirae has been doing this for three months and in three months Mirae has learned like one thing and that one thing is nobody is coming, you know? Nobody is coming because nobody can see you and if nobody can see you nobody knows you need help and if nobody knows you need help then—"
"Nobody comes. Yeah. I know."
More silence. The paint had stopped spreading. It was pooling now, a white lake on gray concrete, and somewhere on the other side of it a person Jiwon couldn't see was deciding whether to trust a voice she couldn't verify.
"Prove it," she said.
"Prove what?"
"Prove you're real. Prove Mirae isn't like — it's been three months, okay, three months of nobody talking back when Mirae talks and Mirae talks a lot, you know, Mirae has always talked a lot, her roommate used to say Mirae could fill a library with the things she said to herself and now that's literally all she does is talk to herself so how does she know you're not just, like — how does Mirae know her brain isn't finally doing the thing it was going to do eventually which is making up a person to talk to because the silence got too—"
"I can move objects," Jiwon said. "In real time. You can tell me what to do and I'll do it. A hallucination can't interact with the physical world."
Quiet. Thinking.
"The paint can. The gray one. On your side of the — wherever you are. Can you see the gray can?"
He looked. The gray can was two meters to his right, cap off, half full. "Yes."
"Pick it up. When Mirae counts to three. Not before. If you pick it up on three, Mirae will know you can hear her in real time and you're not like a, a delayed echo or a recorded loop or something."
"Okay."
"One." A pause. "Two." A longer pause. "Three."
He picked up the can. Lifted it thirty centimeters off the ground and held it there.
From across the alley: the sound of air leaving someone's lungs. Not a gasp. More like deflation. The sound of a belief — *I am alone* — losing its structural support.
"Okay," Mirae said. Her voice was smaller. "Okay, you're real. You're real and you're here and you can hear Mirae and Mirae can hear you and this is — this is real."
"This is real."
"Put the can down. Please. Floating paint cans are like, incredibly unsettling even in context."
He put the can down.

They talked for an hour. They stayed on opposite sides of the alley — not by agreement, just by the gravitational pull of mutual wariness. Two invisible people having a conversation across a puddle of spilled paint, their voices disembodied, their bodies unverifiable. Like a phone call where both parties had forgotten to hang up.
Mirae's story came out the way everything came out of her: in a rush, with detours, doubling back to fill in gaps she'd skipped, interrupting herself to correct details that maybe didn't matter but mattered to her.
She'd been at the Jamsil weekend market. Saturday morning. Buying fabric for a project — a textile piece for her senior thesis, mixed media, "like you take the fabric and you layer it with gesso and then you paint on it but the weave shows through so it's like, it's texture and image at the same time, you know?" She'd been standing near the gate that nobody knew was a gate because it was dormant, classified, scheduled for next week, and then it wasn't dormant anymore. It was open. And beetles were pouring out of it, not the same kind as Hapjeong — these were larger, with mandibles that glowed blue, C-rank, the kind that could shear through a car door.
She'd been hit. Not by a beetle — by a piece of a market stall that the beetles had shredded. A wooden plank, spinning through the air, catching her across the shoulder and the side of her head. She'd gone down. When she opened her eyes, hunters were already on scene and someone was carrying her to a triage point and her status screen was flickering like a bad signal.
"It was like — okay so you know when your wifi is dying, right, and the little icon keeps going from full bars to zero bars to full bars, like it can't decide if it's connected? That's what Mirae's status was doing. Her name would show up and then it would go to [ERROR] and then it would come back and every time it flickered the medic's eyes would like, slide off her for a second, like Mirae would just blink out of his perception and then blink back in."
The hospital had stabilized her. The status had resolved. Fourteen minutes of [ERROR], then normal operation resumed. She'd been discharged with a headache and a bruised shoulder and a note in her file that she'd never seen.
"Two weeks later it started again. In class. Mirae was doing a critique — presenting her work, you know, standing in front of like twelve people — and her professor just stopped mid-sentence. Stopped looking at her. Looked through her. And then everyone else stopped looking at her. One by one, like dominoes, like the — what do you call it when a computer loses connection to devices one at a time?"
"Cascading disconnection."
"Yeah. That. Mirae's classmates disconnected from her one at a time and by the time the last one stopped seeing her, the professor had already moved on to the next student's critique as if Mirae had never been standing there. As if her work wasn't pinned to the wall right behind where she'd been standing. And then — this is the part that really, like — they took down her work. Her professor walked over and unpinned Mirae's pieces from the board and put them in the discard pile. While Mirae was standing right there. Because the System had decided Mirae's work belonged to nobody, and nobody's work goes in the trash."
Her voice cracked on *trash*. Not dramatically. Just a fracture, a hairline crack in the flow of words, and then the flow continued because Mirae didn't stop talking, she processed out loud, the words were the processing.
"She went home. Her roommate didn't see her. She went to her parents' apartment in Songpa-gu. Her mother didn't — her mother opened the door and looked through Mirae and closed the door and Mirae stood in the hallway for I don't know, like, time stopped meaning things around then, you know, Mirae just stood there and eventually she stopped standing and sat down and eventually she stopped sitting and started walking and she walked to the river because the river doesn't need the System to be a river and that was three months ago."
"And the murals?"
"If Mirae can't be seen then at least Mirae's work can. That was the, like, the thesis statement. For this new project that nobody assigned and nobody's grading but is the most important thing Mirae has ever made. The murals are — they're proof. You know? Proof that someone was here. Even if nobody knows who. Even if the System says nobody was."
Jiwon was quiet for a moment. The IT metaphors that usually organized his thoughts were useless here. There was no diagnostic for watching your mother close a door in your face. No error log for a professor throwing your art in the garbage.
"The mural is good," he said. It wasn't enough. Nothing was enough. But it was true.
"Yeah?"
"The negative space. The figure defined by absence. It works."
"Mirae's professor would've given it a C-minus." A wet sound that was trying to be a laugh. "Too on-the-nose. But like, subtlety is for people who have the luxury of being misunderstood, you know? Mirae doesn't have that luxury anymore. Mirae needs to be understood by anyone who happens to walk past that wall, which is like four people a day, one of whom is a cat."
"The cat. Orange?"
"You've met the cat?"
"Different cat. Same energy."
This time the wet sound was closer to an actual laugh. Not close. But closer.
---
The question he'd been holding back since the beginning came out at the forty-minute mark, when the conversation had found a rhythm that wasn't comfortable exactly but was at least sustainable — two frequencies that had learned to occupy the same channel without interference.
"You said you've noticed the Cleanup teams."
"The dark coats? Yeah. They come by like — okay, so Mirae figured this out a few weeks in. After a dungeon break, like within a day or two, there's always a team that shows up at the break site but they're not regular hunters, you know? They don't have the same gear. They don't clear monsters. They just walk around with tablets and scan things and talk into their collars and they're looking for something."
"They're looking for you."
"Mirae knows. Mirae is not stupid, she's an art student not an idiot, she can tell when people are searching a grid pattern. They did it at Jamsil twice. They walked the whole area around the break site in a grid, like a search-and-rescue team except they weren't rescuing anyone."
"How did you avoid them?"
"Mirae is invisible, remember? They can't see her. Nobody can see her. That's the whole, like, that's the entire situation."
"But you said their perception is System-enhanced. They might have other methods."
A pause. Longer than her usual pauses, which weren't pauses so much as the gaps between one sentence and the next sentence that was already forming.
"There's a thing," she said. "A thing Mirae noticed. About the dark coat people."
"What thing?"
"One of them. On the second sweep, like maybe a week after Jamsil. One of them stopped walking. Right near the spot where Mirae had been sleeping — this little alcove under the pedestrian bridge, you know the one near Olympic Park? And he stopped and he did this thing with his tablet where he held it up and moved it around slowly, like he was scanning. And the tablet made a sound. A chirp. Like a — you know how metal detectors chirp? Like that. And he looked at the spot where Mirae had been sleeping like an hour earlier and his eyes — his eyes weren't doing the System thing, you know, the slide-off? His eyes were actually *looking*. Like he could almost—"
"Could he see you?"
"No. Mirae wasn't there, she'd moved. But he could see where she'd *been*. Like a — what would you call it in computer terms?"
"A trace. A residual data signature."
"Yeah. That. He could see Mirae's trace. Which means the dark coats have some way of, I don't know, scanning for where Erased people have been even if they can't see the Erased people themselves."
Jiwon's hand was moving in his notebook before she finished the sentence. *Cleanup unit scanning for null-entry traces. Residual signature detection via modified tablet. Not direct perception — historical detection. They can see where we've BEEN, not where we ARE.*
Which meant his own traces — the jjimjilbangs, the convenience stores, the hospitals, the alleys — were potentially readable by a team with the right equipment. Every location he'd visited was a breadcrumb. Not a live signal, but a historical one. A forensic trail.
"How often do they sweep?"
"At first it was like once a week. Then every two weeks. Mirae thinks they gave up on Jamsil after the second month. They haven't been back in a while." She paused. "But you're here now. And if you've been walking around this area for two days looking for Mirae, that's two days of traces in a concentrated area. Which would look like—"
"A flare."
"Mirae was going to say a big neon sign, but yeah."
Shit. He'd been sloppy. Again. The grid search, the stakeout, the repeated visits to the alley — he'd been laying down traces in a pattern that any competent analyst would flag as anomalous. Not one Erased person's ambient signature but the concentrated residue of an active search, layered over two days in a tight radius.
"We should move," Jiwon said.
"Move where? This is Mirae's area. Mirae knows this area. The alcoves, the warm spots, the buildings with unlocked service entrances. Mirae can't just—"
"If I've drawn attention to this location, the Cleanup team will sweep again. And this time they'll be looking for two traces, not one."
"So you're saying Mirae has to leave because *you* came looking for her and messed up her spot. That's — wow, that's really—"
"I know."
"Mirae was fine! Mirae was *fine* here! Mirae had a system, she had her painting, she had her little routine and you just showed up and—"
"I know. And I'm not going to tell you it was worth it or that this is for the greater good or any of that. I made a mistake. I should have been more careful about my approach. But the mistake is made and we're probably screwed if we stay."
Quiet. The paint on the ground was drying, going chalky at the edges. The handprint was almost gone.
"Where," Mirae said. Not a question. A demand. A single word with no rambling, no verbal tics, no third person — the voice of a person who'd been pushed past her processing speed into something direct and raw.
"I have a contact. Someone with resources. Safe locations, information, operational support. We can—"
"You trust this person?"
"No."
"But you're going to take Mirae to them anyway."
"I don't have a better option."
The sound of someone standing up. Joints cracking — knees, maybe, from sitting on cold concrete. The cardboard shifted. The paint cans rattled as if brushed by a passing body.
"Fine. But Mirae needs to get her things first. Mirae has a bag under the pedestrian bridge. And Mirae wants to know your name, because this whole anonymous-voice-from-behind-a-dumpster thing is going to stop working real fast if we're traveling together."
He hesitated. Oh Jiwon was dead. The news said so. His mother thought so.
"Jiwon," he said. Because the name still fit, even if the person it used to belong to didn't exist anymore.
"Jiwon." She repeated it. Tasting the syllables. "Okay. Mirae and Jiwon. Two error codes walk into an alley. There's a joke in there but Mirae is too tired to find it."
"We need to move. Now."
"Yeah, yeah, Mirae's moving, give her a—"
She stopped. Mid-sentence. The kind of stop that wasn't a pause or a trailing-off but a hard cut, like a process killed without warning.
"Mirae?"
"Shut up." Whispered. Barely a breath. "The bridge. Someone's at the bridge."
Jiwon looked toward the alley entrance. From where he sat behind the dumpster, he could see the bottom of the pedestrian bridge through a gap between the buildings — the underpass, the concrete supports, the drainage grate where homeless people sometimes sheltered.
Two figures. Dark coats. One holding a tablet, scanning it in a slow arc. The other speaking into a collar-mounted communicator, eyes sweeping the area with the methodical attention of someone conducting a perimeter check.
The tablet chirped.
"That's Mirae's alcove they're standing next to," she breathed. "They're at Mirae's spot. They're — oh no, Mirae's bag is there, all of Mirae's things are—"
"Leave them."
"Mirae's sketchbooks are in there. Three months of work. Three months of—"
"Leave them." His voice was low, flat, the register it dropped to when the situation compressed to binary. "South. The other end of the alley. Now. Don't touch anything. Don't knock anything over. Move slow."
For three seconds, nothing happened. The tableau held — two invisible people in an alley, two very visible people forty meters away with equipment designed to find traces of the invisible, and between them a mural of an empty figure that had just become evidence.
Then: footsteps. Light, careful, moving away from him toward the south end of the alley. The sound of someone doing what they'd been doing for three months — disappearing.
Jiwon followed the footsteps into the gray afternoon, away from the mural, away from the drying paint, away from the handprint that was almost gone now but not quite, not completely, still visible as a faint impression in the white — five fingers pressed into the concrete, drying in the air that didn't know she was there.
