Seventeen-year-old Maciek starts seeing reality like code. When a student vanishes in central Warsaw, he and his friends begin to suspect the city is hiding something impossible.
Nowy Świat shone in the last gold light of the day, all glass fronts and warm pavement and people pretending the city was simple. Couples drifted past with ice cream, tourists argued over maps, and waiters hauled tables back under striped awnings. Maciek moved through it all in a navy sweatshirt, thumb brushing the cracked screen of his old phone, looking as ordinary as everyone else.
He hadn’t felt ordinary for weeks.
Lately, conversations reached him before the words were spoken. He would catch a glance, a pause, a tiny shift of breath, and somehow know what came next. At first he told himself it was nerves, lack of sleep, too much caffeine. But the feeling kept growing, turning the air itself strange, as if the world had seams and he had started noticing where they joined. When he stared long enough, he could almost see something beneath everything - lines, patterns, a hidden code flickering in and out of view.
That evening he met Ola and Leon near the Powiśle Power Station, where the concrete walls held the day’s heat and the river wind moved through the trees. Leon had Led Zeppelin leaking tinny and distorted from his phone. Ola sat on the wall with her knees pulled up, watching the dark water. Maciek arrived late, out of breath, and found them already talking about the same thing they always pretended not to believe in.
"Do you ever get the feeling something’s off?" Leon asked, sketching invisible shapes in the air.
Ola didn’t answer right away. Her gaze stayed fixed somewhere beyond the skyline. "Off isn’t the word," she said at last. "It feels edited."
Maciek almost laughed, but the sound died before it left his throat. "I know," he said. "Like someone keeps changing the rules when we’re not looking."
Leon gave him a grin that lasted a second too long. "So maybe we’re the bug in the system."
Before Maciek could answer, a notification flashed across his phone. News. A computer science student had disappeared somewhere outside the University Library, and no one had seen where he went. Maciek stared at the headline until the words seemed to tilt and rearrange themselves.
He barely slept that night. By three in the morning he was on a forum no one he knew would ever admit to reading, scrolling through accounts of streetlights that blinked in impossible sequences, strangers who appeared twice in the same place, numbers that repeated on watches and bus stops and receipts like a warning no one understood. Maciek closed the laptop just before dawn and knew he wouldn’t be waiting for answers anymore.
He’d go looking for them.
The next morning, he, Ola, and Leon stood outside the BUW, the university library looming over them in pale stone and mirrored glass. The entrance doors reflected the street, their own faces, the moving sky above Warsaw - and something else. Maciek narrowed his eyes. Behind his reflection, rows of numbers slid across the glass like a live feed, too fast to read.
A voice brushed the inside of his skull.
You can only change the code if you stay alert.
He jerked back so hard Ola grabbed his sleeve.
"Maciek," she whispered. "Look."
Her eyes had gone faintly green, lit from within like a screen coming awake.
Then a tram screamed past the square and, impossible as it was, stopped directly beside them. The doors hissed open. A boy in a black jacket stepped down, his hand raised just enough for Maciek to see the strange sign burned into his skin.
He looked at Maciek. Then at Ola. Then at Leon.
"You’ve already seen too much," he said.
And beneath Maciek’s closed eyelids, the city exploded into code.
