My phone screen glows in the dark. Each time I tap something, the man lying on my bed twitches. Sometimes his fingers curl. Sometimes his leg jerks. Itâs subtle, but thereâs a pattern to it.
âAlmost done,â I mumble. âJust calibrating your motor sync.â
He doesnât respond. He just lies there, completely still except for those random spasms.
You might be wondering, why is there a bodybuilder laying motionless in the bed with eyes mindlessly opened? Even I couldnât find all of this real. Heck, If someone saw us right now, theyâd probably think I somehow did something awful to the guy. A half-naked guy stretched out on my bed while I stare at my phone like a maniac.
The progress bar moves across the screen. Neural Sync: 82%.
I shake my head. âIt still sounds insane when I say it out loud⊠but this guy, the one who lives next door, the one I thought was just a rude gym broâturns out, heâs a robot.â
I set my phone down and look at him again. âTwo weeks ago, I didnât know any of this.â
=========================================
Iâd just moved into my new apartment after finishing my degree in IT and engineering. It was supposed to be a quiet start to a normal life.
The building had a public gym on the first floor. I passed by it while carrying boxes, glanced through the glass, and saw a few people working out. But one guy caught my attention a tall, built, clearly dedicated. Even from that quick look, I knew he was someone people noticed.
I didnât think much of it and went back to moving my stuff.
Later, when I stepped out to grab another box from the hallway, I saw that same guy again â walking toward me, gym bag slung over his shoulder.Â
He stopped at the door next to mine.
I tried to be friendly. âHey, I just moved in. Nice to meet you.â
He looked at me, expression unreadable, and without saying a word, opened his door and went inside.
I stood there, half-annoyed, half-confused. âOkay,â I muttered. âGuess thatâs one way to say hi.â
Over the next few days, life in the new apartment slowly settled into a rhythm. I was still getting used to the place â unpacking, organizing, learning which light switches actually worked, and wandering around the neighborhood whenever I needed a break from staring at empty boxes. The area was decent: quiet streets lined with small cafĂ©s, a few parks, a shopping block with hardware stores and laundromats, and that faint hum of city noise that never quite disappears.
I tried to make it a habit to explore. It gave me something to do while I looked for a job. But something started feeling⊠off. Not scary, not threatening, just weirdly coincidental.
Everywhere I went, that same guy from the gym â my next-door neighbor â showed up.
The first time was in a small side street behind the apartment complex. Iâd taken a detour to avoid the main road, and there he was, walking stiffly down the sidewalk. He had those massive over-ear headphones on, his expression blank, eyes focused straight ahead. I remember thinking he looked⊠mechanical, almost too composed. His posture didnât change even when I passed by him.
The second time was in the park. I was eating a sandwich on a bench, scrolling through job listings, when I saw him again â jogging along the trail that looped around the lake. His pace was steady. The same length of stride. No breaks. He didnât slow down once. Even when he circled around for another lap, his speed hadnât changed at all. Not faster, not slower. Just perfectly consistent.
The third time was in the shopping district, near the hardware and electronics stores. I was there to buy a few extension cords, and there he was again, standing by the counter with a few electronic components in hand. Not the kind of stuff youâd expect a gym bro to buy â more like wires, connectors, and small circuit pieces. For a moment, I wondered if he was also into tech, maybe even an engineer. But he didnât seem like the type to start small talk, so I left him alone. Still, the coincidence bugged me.
âOkay, what are the odds?â I muttered as I walked back home.
I tried brushing it off. Maybe it was normal. Maybe he just happened to frequent the same places I did. After all, it wasnât a huge neighborhood.
But as the days went by, it got harder to ignore.
I had too much free time, so I ended up noticing things that most people wouldnât. Like how every morning, at exactly the same minute, heâd step out of his apartment wearing his running gear. Same route, same jog, same expression. I could practically set a clock by him. He never skipped a day. Not once.
And it wasnât just his discipline that felt strange â it was the precision. His movements were identical day after day, as if his entire routine was preprogrammed. The angle of his arms when he ran, the number of steps before turning the corner, the duration before returning. It was all too exact.
I told myself I was overthinking it. Some people just have strict routines. But even the most disciplined athletes break rhythm once in a while. They get tired, sick, lazy. They miss a day. This guy? Never.
The weird part didnât end there. For someone who looked like a textbook extroverted gym bro â muscular, confident, probably popular â he was completely silent outside of his runs. No visitors, no noise, no life coming from his apartment at all.
These walls are paper-thin; I could hear the couple across the hall arguing over what to watch on Netflix, the old lady two floors down playing her morning radio show, and even the neighborâs cat meowing at all hours. But from his apartment? Nothing.
For someone wearing giant headphones in his head, he doesnât listen to music out loud. No TV. No footsteps. Not even the faint sound of weights being dropped or a shower running. Heâd walk in after his jog, close the door, and vanish.
Sometimes, late at night, when I passed his door on the way to throw out trash, Iâd pause and listen. Still nothing. The silence was almost unnatural â heavy, deliberate, as if the space itself stopped existing once he was inside.
It gave me chills sometimes. But again, I told myself it wasnât my business. Everyoneâs got their own life. Maybe he just liked privacy. Maybe he worked night shifts or meditated or something.
Whatever it was, I decided not to care. Even if something about him didnât add up. Even if every coincidence made my stomach tighten a little more each day.
Because, really â who was I to question my quiet, perfectly strange neighbor?
==============================================
By the second week, I had completely fallen into the unemployed routine. Wake up late, check emails that never came, scroll through job sites, and eventually end up tinkering with my old projects to keep my brain from melting.
One of those projects was something Iâd started during my last year in university â a compact signal hijacker I called Specter. It was supposed to be a proof of concept, a device that could connect to any signal â Wi-Fi, Bluetooth, radio â and manipulate it while keeping the user completely invisible.
If it worked the way I designed it, Specter wouldnât just let me listen or read signals. It would give me control over them. Every packet of data would route through my encryption shell, a design so unique that any attempt to decode it would essentially destroy the machine trying to do so. At least, that was the theory.
Maybe, I thought, if I could refine it and sell the patent, I might actually make something of myself.
That afternoon, I decided to test it again. I connected Specter to my phone as a proxy, powered it up, and watched as the screen flooded with nearby connections.
There were dozens. Neighborsâ Wi-Fi, smart TVs, speakers, even refrigerators and washing machines. I could tap into any of them with a few swipes.
A connection named NACN_T331 kept appearing and disappearing from the list â flashing in and out like it was there one second and gone the next.
It wasnât a regular network. The frequency range was strange. The signal wasnât stable, almost as if it was moving.
âHuh,â I muttered, leaning closer. âWhat are you?â
Curiosity got the better of me. I locked onto it and ordered Specter to start decrypting.
Immediately, the device began to heat up. Lines of code ran across the screen as it tried to latch onto the shifting signal. It was like wrestling smoke â the more I grabbed, the more it slipped away.
âCome on⊠youâve cracked encrypted routers before, this should be easy,â I whispered.
The minutes stretched on. The air smelled faintly of warm plastic as Specterâs casing grew hot. My phone flashed warnings Iâd never seen before â CPU overload, thermal protection active â but I didnât stop. I was too deep into it now.
Then, finally, the connection locked.
I sat back, grinning. âHa! Got you!â
Thatâs when I heard it.
A loud, heavy sound came from next door. My grin froze.
âUhâŠâ I waited. Silence followed. Then another faint noise, like something collapsing.
Panic replaced the rush of excitement. I threw on a hoodie, grabbed my phone, and rushed out into the hallway.
I knocked hard on my neighborâs door. âHey! You okay in there?â
âHello? I heard something fall!â I called again, knocking faster. âIâm sorry if Iâm overreacting, but it sounded badââ
I hesitated, then tried the doorknob. It turned easily. Unlocked.
âOkay, weirdâŠâ I muttered, pushing the door open carefully. âUh, Iâm coming in, alright? Just checking if youâre fine.â
The moment I stepped inside, I froze.
The apartment was⊠empty. Barely even furnished. No couch, no TV, no shelves, nothing. Just plain walls and a single cabinet shoved into a corner. The floor was scattered with a few things â a cracked phone, a pair of large headphones, and some loose wires that looked like theyâd been ripped out of something.
Face blank, eyes half-open, body twitching in small, erratic spasms.
âHeyâhey! Are you okay?â I rushed over, kneeling beside him. His skin looked pale, and his breathingâwell, I wasnât sure it even was breathing.
He mumbled something faintly.
My blood ran cold. âWhat?â
âError⊠error⊠errorâŠâ
He repeated it, like a broken recording.
I leaned closer. âWhat are you saying? What happened to you?â
Then his head jerked slightly, and for the first time, his eyes focused â not on me, but on the empty wall in front of him.
In a flat, robotic tone, he said, âNetwork database compromised. Source unidentified. Current unit integrity: failed. Commencing full reformat.â
I just stared at him, completely lost. âReformat? Whatâwhat are you talking about?!â
His pupils flickered unnaturally, and his voice repeated, slower this time: âThis unit will be wiped clean.â
I stumbled back, confusion twisting into realization.
That strange network⊠NACN_T331. That was him. The signal had been coming from him.
And my device â my encryption â it must have overwhelmed whatever system was controlling him. The feedback loop would have fried anything trying to trace or fight it. Which meant whoever was behind this, whoever owned this so-called âunit,â couldnât recover it.
So they did the only thing they could.
They erased him.
Leaving behind this â a blank, motionless shell of a man, twitching on the floor where my neighbor used to be.
I stood there, speechless, heart pounding, my own invention still humming faintly in my pocket.
âWhat the hell did I just do?â I whispered.Â
I looked at the âunitâ in front of me, wondering what will happen next. A few minutes, go by, nothing. The puppet strings of this âmanâ is truly been severed.Â
âWell, we have to do what we get to do, right?â I smirked as I fiddled with my phone and gadget. Regardless of what he was and what this âthingâ originates from, it's now mine to keep, and Iâd gladly take this junk of a hunk under my wing. Using the already compromised network emitting from this man, I can hack through his systems, replace the erased data, and rebuild everything that will shape this hunk of a man into my liking!
âLetâs see what can I do with you!â
==============================================================
A month later, the apartment had become almost unrecognizable. Where it was once empty and quiet, it now felt lived-in â clothes tossed over the couch, a few dumbbells stacked in the corner, two mugs sitting side by side on the counter. The faint scent of detergent mixed with protein powder hung in the air.
The front door clicked open.
The familiar voice echoed through the small space before Jin appeared in the doorway, fresh from the buildingâs gym. His tank top clung to him, soaked in sweat, his skin glistening under the ceiling light. His expression, however, was bright and cheerful â a warm, genuine smile as if he were coming home from a long day to his favorite person.
âHey, youâre early,â I said from the couch, where I was hunched over my laptop.
âLeg day, bro. Gotta cut it short before I start walking like a duck again,â Jin replied with a grin, dropping his gym bag by the door. He ran a towel over his neck, then stepped closer, peering at my screen. âStill working on your nerd stuff?â
I rolled my eyes. âYeah, some of us use our brains instead of our biceps.â
He snorted. âJealous much?â
I laughed, âIn your dreams, musclehead.â
Jin chuckled, tossing the towel aside as he flopped down next to me on the couch. It was easy to forget, sometimes, that this same man was once lying lifeless on his apartment floor just a month ago. Now, he was everything I had designed him to be; confident, outgoing, charismatic, playful, the kind of extroverted personality that used to intimidate me.
âWell,â I said, leaning back, âlooks like the new behavior moduleâs working.â
Jin raised an eyebrow. âYouâre talking like Iâm one of your gadgets again.â
I smirked. âTechnically, you are. But donât take it personally â I just modeled your personality based on what I thought youâd be like if you were⊠human. Yâknow, cool, outgoing, a little frat-boy-ish. Like the version of you everyone expects to meet at a gym.â
He laughed softly, flexing his arm. âSo basically perfect?â
âYeah, yeah,â I muttered, waving him off. âPerfectly annoying.â
That made him grin wider. âAdmit it, though~ Iâm your favorite creation, right?â
He leaned closer, bumping my shoulder playfully. âNot maybe. Definitely.â
I couldnât help but smile. The banter felt easy now, natural, like weâd been friends for years instead of just a few weeks. We talked about everything and nothing: dumb gym stories, memes, jokes about my nonexistent social life. Jin loved teasing me, and I didnât mind it; it filled a silence that I hadnât realized was eating away at me. Though, Somewhere between laughter and small talk, though, something shifted.
Jin stood, stretching, his muscles tightening and relaxing as he pulled his damp tank top over his head. Then, with a mischievous grin, he turned toward me, dangling the sweaty fabric from his fingers.
âCatch,â he said. but instead of throwing it, he stepped forward and brushed it against my face and neck, dragging it playfully across my skin.
âJinâugh! Come on!â I sputtered, pushing him away, but he only laughed and leaned in closer.
âWhat? Iâm just sharing the gym experience,â he said teasingly, his tone dipping lower, softer.
His demeanor changed almost imperceptibly â less teasing, more affectionate. He crouched slightly, meeting my eyes. âYou know⊠I donât think Iâve ever told you this, but I like being here. With you.â
The joking atmosphere turned warm, intimate. His hand rested on my shoulder, firm but gentle. âYou made me, right? So I guess it makes sense that youâd be the center of my world.â
My throat went dry. âHeh heh⊠yeah~ but Jin, thatâs⊠a little much.â I cough, â a bit cheesy tooâŠâ
He didnât stop. His expression softened into something almost tender, though still threaded with that exaggerated bravado Iâd programmed in him. âBut I really do mean it. Youâre everything I need.â
Before I could react, he moved closer, wrapping one arm around me and pulling me into him. My head pressed against his torso, his abs firm and unyielding against my face. âD-Dude, I like this but, seriouslyâlet go!â I laughed, half embarrassed, half stunned.
Instead, he tightened his hold, his voice dripping with affection. âNope. Youâre not going anywhere, bro.â
I could feel the faint vibration in his chest when he spoke. âYou wanted me to be loving, right? Guess I overachieved a little.â
I groaned, trying to wriggle free. âYou think?! Youâre suffocating me, you oversized golden retriever!â
He only chuckled, resting his chin on top of my head like he was perfectly content to trap me there.
Thatâs when I realized Iâd definitely overprogrammed the âromantic attachmentâ variable.
âAlright,â I said loudly, patting his arm. âTime to chill, lover boy. Systemââ
He froze immediately, the muscles around me locking in place like cooled steel. His eyes went blank, his expression neutral.
I exhaled. ââSuspend Command: Solstice Mode.â
That was the name Iâd given his system freeze function. It sounded more poetic than just shouting pause program.
Stepping back, I grabbed my phone from the coffee table and opened the control interface. The hijacking device had evolved since the first incident â sleeker, faster, with deeper access to Jinâs neural systems. I connected to his signal and began typing commands as I flip Jin's body upright.
Lines of data scrolled across the screen as I rewrote parameters, adjusted emotional thresholds, tweaked behavioral directives. His body reacted slightly to each new input â his shoulders flexed, his chest rose, his head tilted just a fraction.
âWow,â I said quietly, watching him. âYou really are something else.â
A faint electrical pulse ran through him, visible in the small contractions along his arms. He looked like a perfectly sculpted statue brought to life mid-motion.
âAlright, letâs seeâŠâ I muttered, typing. âDial back the clinginess, increase self-restraint, keep the affection⊠but make it less smothering.â
As I finished entering the new code, Jinâs body flexed involuntarily â a sudden, powerful motion that made me laugh despite myself.
âWoah, damn! What an extra way to reboot,â I said, shaking my head. I reached out, tapping his shoulder lightly. âGuess youâre still learning how to chill, huh?â
His eyes blinked once, life flickering back into them.
âSystem reconfiguration complete,â he said automatically, then smiled, the warmth returning.
I grinned, setting my phone aside. âHeh. I guess weâve still got a long way to go.â
He tilted his head. âThat a bad thing?â
âNot at all,â I said, leaning back in my chair. âNot at all.â
