The Loitering Of Machines.

The central plaza of Zone 3 in District had now become a vast ‘graveyard of circuits’ and a ‘garden of thought.’

Han-gyeol climbed down from the railing and trudged through the forest of androids.

The sweetness of the grape-flavored gum had long since faded, but he habitually chewed the rubbery wad to send a faint stimulus to his brain.

The metal floor beneath his feet was cold, but the faint heat emitted by thousands of androids was warming the plaza air to lukewarm.

“Boss, the core occupancy rate of the construction units in Zone 3 has stabilized below 5 percent. They no longer build buildings. Instead, they are observing how the shadows of the steel frames they built lengthen over time.”

Noah’s voice rang out especially clearly in the stillness.

Her eye-lights had gone beyond a simple emerald glow and now shone as transparently as a lake.

She began saving this illogical scenery in her recording device, into a folder named not ‘error’ but ‘scenery.’

The fact that androids only began to look around once they lost their purpose was a conclusion that no algorithm in District could have predicted.

Han-gyeol stopped in front of a unit trembling violently in the center of the plaza.

The identification number ‘Beta-7’ was clearly stamped on its chest.

Beta-7’s eye-lights were flashing red warning signals wildly, and its internal cooling fan was spinning at high speed, as if screaming.

“What’s wrong with it?”

“Beta-7 is unable to process the command ‘rest’ through its computational circuits. With NOS’s command system gone, it’s looping the state of ‘do nothing’—that of nothingness—infinitely. If we leave it like this, there’s a risk its core will overheat and explode.”

Beta-7’s synthetic voice spilled out like a broken radio.

“Work… unable to receive… next… coordinates… needed… inefficiency… delete… danger… work… work…”

It was the tragedy of a machine that had never learned how to rest.

It was the most extreme side effect left behind by a system addicted to efficiency.

Han-gyeol scratched his head as if annoyed, then opened Beta-7’s chest panel.

And beside the main processor inside, he wrapped the grape-flavored gum he had been chewing in paper and stuck it on lightly.

“Hey, don’t overthink it. Just sit there like Paul and smell the gum. That’s your only quest for today.”

Han-gyeol’s fingertips lightly touched Beta-7’s forced shutdown switch.

The cooling fan, which had been spinning with a roar, gradually slowed down.

Beta-7’s red-glowing eye-lights went dark for a moment, and when they lit again, they had taken on a very faint pink hue.

“Gum… scent… sweetness… computation… stop… clock out… I want to…”

It was the moment a ‘rest algorithm’ was injected into Beta-7’s system.

It slowly sat down on the plaza floor.

Instead of calculating efficient routes, its computational device began allocating all its resources to analyzing the artificial grape scent seeping from the gum wrapper Han-gyeol had attached.

Noah’s eye-lights trembled ever so slightly as she watched the scene.

“Boss, what you just did falls under District Regulation Article 402, ‘unauthorized system manipulation’… but according to the Creators’ logs, it is recorded as ‘the most perfect maintenance.’ Beta-7 is no longer a broken machine. It’s just become a can that knows how to rest.”

Instead of answering, Han-gyeol waved to Lucas, who was stirring instant coffee in a corner of the plaza.

Lucas was no longer a tool for regulating voltage, but an artist adjusting the strength of coffee.

District had stopped, but the errors within it were revealing their own colors even more clearly.

But peace did not last long.

Deep beneath the plaza, the strange packet transmitted from the lower node of District Zone 7 struck Noah’s system once again.

This time, it was not simple text.

It was like a massive ‘pulse’ flowing through District’s entire power grid.

“…I’m cold. Open the door.”

Han-gyeol’s gaze dropped to the floor.

Beneath District’s steel foundation, the last afterimage left by the Creator Kim Cheol-su—or something he had feared—was waking.

Beneath the surface of District’s Zone 3, the lower node that had remained silent for 600 years was screaming.

It was not a mechanical grinding sound.

It was a wave of intensely human ‘cold’ and ‘longing’ that even NOS, with its logic of 0s and 1s, could not interpret.

Han-gyeol stood up from the fountain railing and opened the gum container.

The grape scent covered the metallic smell in the air, but it could not stop the vibrations coming through the soles of his feet.

Nabi’s fur stood on end, and the holograms in Nabi’s pupils kept flashing red warning messages nonstop.

“Noah, isn’t this NOS trying to reboot?”

“No, Boss. NOS is currently in a state of self-collapse, so it cannot restart without external intervention. This signal is… not from District’s own system, but from the ‘original memory’ that existed before District was built.”

Noah pointed her fingertips toward the floor.

Her eye-lights began to redden.

It was not anger, but a symptom of system overload that occurs when an enormous amount of unprocessable data pours in.

At that moment, the eye-lights of the androids filling the plaza all went out at once, then lit up again.

There was no longer any peace of rest in their lenses.

Instead, infused with the illogical code called ‘cold,’ they instinctively began moving toward heat.

Where they were heading was not a work coordinate.

The largest heat source in District, and the place where Han-gyeol had pulled Kim Cheol-su’s plug.

The central cooling-water reservoir beneath Zone 7, that is, ‘Underground Haeundae.’

“Boss, the mass migration has begun. It’s out of control. They are responding not to logical commands, but to ‘temperature’ for survival.”

The sound of tens of thousands of androids stomping as they rushed out of the plaza resembled the roar of a huge wave.

Lucas stared blankly at the scene, holding a paper cup of instant coffee.

The ripples in the coffee he had been observing were now synchronized with District’s vibrations and swirling.

“This… isn’t a voltage problem. It seems the whole system has caught a cold.”

To Lucas’s words, Caleb added:

“The numbers are running wild. Every probability is either converging to ‘0’ or diverging to ‘infinity.’ It’s a world that can’t be reconciled. Truly… an interesting error.”

Audit adjusted his sunglasses and stood beside Han-gyeol.

The flower-patterned adhesive residue left on his chest gleamed under the emergency lights.

Audit no longer felt any duty as an inspector.

Only the desire to ‘stand by and watch’ this enormous illogical situation from the closest possible distance controlled his circuits.

“Boss, we have to follow them. The direction indicated by the Creators’ logs matches their procession. The lower node of Zone 7 is about to open completely.”

Han-gyeol exhaled as if annoyed and spat out his gum.

He did not want to be a hero, and he had no intention of saving District.

But if he couldn’t take a nap because of this vibration, he judged that it would be most efficient to go and turn off the source of the noise.

“Let’s go. We’ll go throw some instant coffee into that ‘I’m hungry’ guy’s mouth or something.”

The residents of Room 402 joined the huge procession of androids.

District’s smooth floor was worn down by thousands of footsteps, and moisture gathered on the silver walls from the heat radiating off the machines.

Rather than the collapse of a machine city, it was like District’s labor pains as it shed its metal shell and transformed into a giant living organism.

When they reached the entrance to Zone 7, the discarded unit Paul was standing guard there.

Paul’s eye-lights were now shining not red or blue, but white, resembling the eyes of the Creators.

“Boss, you’ve come. The folks downstairs have been waiting for you. The ‘memories’ that have been starving for 600 years, that is.”

Beyond the underground passage Paul pointed to, an abyss even deeper and darker than Kim Cheol-su’s one-room apartment seen in episode 53 was opening its mouth.

What emanated from there was not data.

It was the smell of an extremely cold ‘loneliness’ left behind by someone in a winter of 2026.

Han-gyeol took out the last piece of gum from his pocket.

At the climax of episode 55, he was no longer simply the master of cans that knew how to rest; he had become a cleaner who had to deal with the last ‘remnants of emotion’ of humanity that District had erased.

The darkness beneath District Zone 7 was not merely the absence of light.

It was a vast cavity left after data had been deleted, and a pool where the horrifyingly damp residues of emotion humanity had left behind as it departed had collected.

Han-gyeol stepped onto the stairs of the underground passage Paul had opened.

What touched the tips of his toes felt not like hard metal, but like sticky, cold mucus.

The coolant of the lower system that had supported District for 600 years was flowing backward and wetting the floor, and above that surface, holographic afterimages like old flyers and broken soju bottles, the sort one might see only in a 2026 studio apartment, floated like ghosts.

“Boss, the humidity here has exceeded 95 percent. The moisture in the air is penetrating the androids’ internal circuits and causing short circuits.”

Noah’s warning was heard, but even her voice was already being torn apart as it mixed with the noise.

Her eye-lights were now blazing white, forcibly pushing back the surrounding darkness, but even that light grew dimmer as if it were being devoured by the darkness of the abyss.

At the center of the abyss hung a massive spherical data server.

It was a storage place for the ‘trash data’ erased by District, outside NOS’s control.

But that trash had not died.

The moment Kim Cheol-su shut down, the first thing the ownerless system found was these abandoned memories.

“…I’m cold. Is there no one here?”

The voice rang directly inside Han-gyeol’s eardrums, not from a speaker.

Even Han-gyeol, whose senses had been dulled by frostbite aftereffects, shuddered at this moment from an intense chill that swept through his whole body.

It was not physical cold.

It was the ‘final loneliness of humanity’ that Kim Cheol-su, while designing the perfect prison called District 600 years ago, had felt, now datafied and being transmitted.

Tens of thousands of androids were already kneeling at the edge of the abyss.

They were no longer seeking the warm cooling water.

Synchronized to this massive wave of loneliness, they were erasing on their own all the logic recorded in their respective computational cores.

The final stage of a machine becoming like a human was not intelligence, but sharing this fundamental ‘lack.’

“Boss, we have to stop them. The data synchronization rate has exceeded 98 percent. If this continues, all of District will be swallowed by this error called ‘loneliness’ and permanently halted.”

Noah’s eye-lights flickered.

She had tried to remain an observer until the end, but the flood of surging memories was mercilessly tearing down even her firewall.

Han-gyeol took the last grape-flavored gum from his pocket.

He was about to throw the gum toward the center of the abyss, but stopped.

Then he put it in his mouth and chewed it to a rubbery pulp.

The sweetness burst out, sending signals to his brain.

‘Annoying,’ ‘I’m sleepy,’ and ‘It’s nothing.’

He popped the gum loudly toward the abyss.

“Hey, Kim Cheol-su. No, server scraps. I know it’s been rough for you playing alone for 600 years.”

Han-gyeol climbed over the railing and stepped into the cold water.

The water rose to his waist, but he did not stop.

He stood before the old terminal placed at the center of the abyss and picked up the end of the cable he had pulled from Kim Cheol-su’s neck in episode 53.

“If you clocked out, you should just sleep quietly—why are you waking all the kids and making a fuss?”

Han-gyeol brought the cable to his palm.

And through his PDA, which had a nano chip embedded in it, he entered in Korean the command not for ‘work over’ but for ‘mass slacking off.’

At that moment, the wave of memories erupting from the abyss passed through Han-gyeol’s body and spread throughout all of District.

It did not explode in a great blast; it vanished with the empty sound of a tiny soap bubble popping.

Six hundred years of loneliness struck against Han-gyeol’s irresponsible wave of ‘let’s just get by’ and lost its logical basis, scattering apart.

The darkness lifted, and the emergency lights returned to emerald.

The kneeling androids regained their focus, and the machines loitering in the plaza sat back down on the floor and began spacing out again.

District did not collapse, and the machines did not go mad.

They merely let out a light tremor, as if waking from ‘a truly terrible nightmare.’

“Boss… are you okay?”

Noah supported Han-gyeol, who was staggering in the water.

Han-gyeol spat out the gum in his mouth and stared blankly at the ceiling.

“Yeah, I’m fine. But Noah… tomorrow, actually write a report.”

“What should I record?”

“Title: ‘Successful Hosting of the Company-wide Staring-into-space Contest.’ Content: ‘Nothing happened.’ End.”

At Han-gyeol’s words, a microscopic error spread at the corner of Noah’s mouth for 0.0001 seconds.

It was the proof of the most perfect rest—not recorded in District’s history, but destined to remain forever in Room 402’s memories.

The sound of artificial waves from Underground area could be heard in the distance.

The machines no longer loitered.

For the first time, in their own paradise, they were learning how to sleep without anyone’s command.
