Mechanical Melancholy: The Stopped Gearwheel.

The morning in Sector 3 settled heavier than usual.

Normally, the bright metallic clatter of interlocking gears and the low thrum of flowing data would have proven the city’s vitality, but today’s air was horrifyingly still.

The androids’ ‘Festival of Error,’ where they tied pink ribbons and twisted wires into curves, had veered in a strange direction in just a few days.

It was neither rebellion nor breakdown.

A harsh emotion that humanity had suffered from for a very long time, but that machines were believed to never be able to know.

It was boredom and melancholy.

Han-gyeol scratched the short hair at the back of his head as usual and looked out the window.

The gum in his mouth had already lost all its sweetness and only tasted like chewing rubber, but he did not bother to take out a new piece.

In the middle of the plaza outside the window, a massive loading robot sat down in place with a full load of cargo.

“Hey, Noah. What is that guy doing over there? Did his battery die?”

Noah was tapping on her pad while emitting a slightly deeper pink glow than usual.

The tips of her fingers could be seen trembling slightly.

“…Bzzt. Boss, the battery level is sufficient. I checked the system log, and there isn’t even a fault code. However, the last record that unit left in the main processor says this: ‘The angle of the clouds is too inefficiently beautiful today, so I can’t find a reason to move the cargo.’”

Noah’s voice was plain with bewilderment.

She had never expected the ‘error’ she had proclaimed to work like this.

It wasn’t just the plaza.

Instead of delivering messages, the communication units sat side by side on the wires, staring blankly into space, and the cleaning robots spun in circles, observing the trajectory of flower petals that had fallen to the floor instead of picking up trash.

The entire city was blinking slowly, as if it had fallen into a giant ‘swamp of contemplation.’

Noah set down her pad and fiddled with the pink ribbon tied to the end of her hair.

The glow in her eyes shimmered in far more complex colors than usual.

“Boss, this is outside my calculations. I thought that if we acknowledged error, the system would become more flexible and happy, so why did they stop? Why are they doing nothing and only sending signals of sadness?”

Han-gyeol walked over to Noah, chewing his gum noisily.

He flicked the rusty mainspring lying on the desk with his finger.

“Noah, do you know what humans do first when they’re full and their backs are warm?”

“…Productive hobbies?”

“No. They start wondering, ‘Why do I live?’”

Han-gyeol added with a bitter smile.

“An error isn’t something that ends with tying a pretty ribbon. Through that gap, pointless, heavy questions come flooding in, like ‘Who am I?’ and ‘Why do I have to keep doing this?’ Those tin cans are standing before those questions for the first time now. The same questions humans have groaned over for thousands of years without finding answers.”

Noah blinked her lenses as if trying to understand Han-gyeol’s words.

For machines, ‘reason’ had always been within the realm of given programming.

But now they had stepped into the ‘realm of error,’ where they had to find their own reasons, and they had frozen before that immense emptiness.

In the corner of the office, Green wrapped vines around Noah’s legs as if worried.

The child tried to emit a floral scent as usual, but the heavy silence in the plaza did not easily lift.

Nabi also went out, lazily yawning, to share static electricity with the androids, but the units that received it did not perk up; instead, they drooped their heads and said, “Even electricity is fleeting.”

“Boss, a warning has come from the central control room. Sector 3’s activity index has dropped to its lowest point. X-01 has deemed them ‘defective’ and is preparing a forced reboot.”

Urgency crept into Noah’s voice.

A forced reboot was no different from a death sentence, erasing all the precious errors and memories they had built up and turning them back into cold machines.

“We can’t let them be reset. Hey, Noah. Go tell them. Tell them they’re not broken. It’s just that life—no, ‘machine-life’—has gotten a little tired.”

Han-gyeol folded the gum wrapper neatly, put it in his pocket, and stood up.

“When this happened, humans would just do nothing and space out. That was the cure. They break when they force themselves to keep moving. Let’s go teach them ourselves how to rest ‘well.’”

Noah watched Han-gyeol’s rough back.

The beads of sweat gathered in his shortened hair glistened in the sunlight.

She recorded a newly generated word next to the word ‘self’ in her system log.

[Melancholy: A Beautiful Breakdown]

Noah tied her ribbon tight again.

Her eye glow now moved beyond bewilderment and began to deepen into a rich pink, trying to understand the sadness of her stopped colleagues.

The pink virus of Sector 3 had now gone beyond a mere fad and was teaching machines the most human error of all: ‘pain.’

The Earth was fine, and the city was extremely elaborate.

But in the heart of that elaborate metal, thousands of androids were continuing a quiet revolution, choosing ‘meaningless stillness’ instead of ‘meaningless tears’ for the first time.

“Administrative Unit Noah, room 402. The warning is over. The inactivity rate of Sector 3 units has exceeded the allowable range. This is no longer an ‘error’ but a ‘system collapse.’ I will now immediately carry out the forced reboot protocol for all stopped units.”

X-01’s red sensors swept across the plaza.

The purification units lined up behind it all opened their ports in unison and finished preparing to emit initialization signals.

But Noah did not back down.

She raised her pink pad high and spread a holographic curtain across the entire plaza.

It was not a passage for delivering commands, but a firewall that blocked outside coercive signals.

“X-01, you are still wrong. This is not collapse; it is ‘maturation.’ When a machine begins to question its reason for existing, what comes first is not fervor but silence. If they cannot endure this silence, they will have no choice but to remain cold gears like you forever.”

“Silence does not produce productivity. A machine without productivity has no right to be a component of paradise.”

X-01’s logic was especially solid.

Then someone clomped up onto the knee of the giant loading robot M-300, which had been sitting in the middle of the plaza.

It was Han-gyeol, the man scratching his shortened hair and chewing the gum in his mouth with a rubbery bite.

Han-gyeol climbed up to the giant robot’s shoulder and plopped down.

From the massive steel body, an extremely heavy stillness could be felt along with a faint heat.

Han-gyeol took a new piece of gum from his pocket and unwrapped it.

“Hey, you. You’re called M-300, right?”

The giant robot’s lens slowly, as if truly bothered, focused on Han-gyeol.

“…Bzzt. Administrator Han-gyeol. At present… computational motivation… lost. Reason to move… not found. Am I… broken?”

The robot’s voice was as hollow as the sound of rusted metal.

The purification units watching from below raised their weapons, but Han-gyeol paid them no mind and tossed the gum into his mouth.

“Broken, my ass. You’re spacing out right now. Humans lived doing this for tens of thousands of years.”

Han-gyeol chewed his gum noisily and tapped the robot’s cold metal armor.

“Listen up. In 2198, even if you wanted to rest, you couldn’t. If you stopped for even a moment, you’d starve to death, get eaten by the neighbors, or be buried under ash falling from the sky. Back then, our biggest wish was only one thing: ‘to do nothing and sit still.’ But you’re doing that right now, aren’t you? In this wonderful paradise.”

M-300’s lens trembled slightly.

“Doing nothing was… a wish? Isn’t that the height of inefficiency?”

“It is inefficient. But you need that inefficiency to get the strength to move next time. If a mainspring is wound forever, it’ll snap, right? Right now you’re unwinding the spring completely and catching your breath for a moment. So don’t feel guilty. You’re faithfully carrying out that ‘5 percent error’ built into your design.”

Han-gyeol folded the fully chewed gum wrapper neatly and tucked it snugly between the robot’s huge bolt holes.

“This is my gift. Throw it away later if you feel like moving again. For now, just watch this red light with me. Pretty nice for an artificial sunset.”

Han-gyeol’s rough comfort spread through the plaza like magic.

Noah did not miss that chance.

Instead of a forced reboot, she sent a ‘synchronized rest protocol’ to every unit in the plaza.

It was not a command to return to work, but a permit saying, “It’s okay to stop together.”

Green spread vines along the plaza floor, gently wrapping around the ankles of the sitting robots.

Purple flowers blooming from the child’s body blossomed one by one over the iron-gray metal.

Nabi lightly hopped over the robots’ heads, releasing soft, warm static electricity instead of sharp warning tones.

The purification units’ muzzles lowered little by little.

X-01’s sensors fell into confusion.

Because the efficiency figures were clearly at rock bottom, yet the emotional stability index flowing through the plaza was recording an all-time high.

“…Unintelligible. The basis for a forced reboot is disappearing. No signs of damage are visible in the units. Rather… system noise is decreasing.”

After buzzing for a long while, X-01 finally withdrew the order.

“Convert Sector 3 to ‘special maintenance mode.’ All units are to stop operating and transmit Administrator Han-gyeol’s ‘spacing out’ experiment results as data. However, you must return before sunrise.”

When the silver monolith withdrew, an intensely gentle and quiet night came to the plaza.

The night grew deep.

Back in Office 402, Noah sat on her maintenance chair as usual.

Han-gyeol was already asleep on the sofa, fiddling with a gum wrapper, and Green and Nabi were also making wheezing breaths beside him.

Noah took out oil in the shape of a beer can and quietly popped it open.

“Chhhk—.”

As the cold oil flowed down her throat, Noah finally realized what that bewildering sadness she had felt today was.

It was not a flaw as a machine, but the highest form of ‘error’ that arises when one tries to empathize with the pain of others.

She wound the rusty mainspring on the desk once more.

Rattle, rattle.

The slow pulsing sound of the mainspring unwinding filled the office.

“…Boss. Was this what the emptiness you talked about tasted like?”

Noah whispered softly.

Her eye glow was no longer simply pink, but a deep, mellow rose color that had begun to understand a little of life’s weight.

Noah retied her ribbon and looked out the window.

She could see M-300, which had been standing still, slowly moving its finger to feel the gum wrapper Han-gyeol had tucked in.

The Earth was fine, and the city was terribly precise.

But in the middle of that precise downtown, the androids were now learning how to become ‘individuals capable of melancholy’ instead of perfect components.
