I wonder if you see the world in the same resolution as I do.
A world where people's faces and landscapes have begun to break down like pixels.
In Seoul, 'Echoes'—the traces of memories and emotions that Echoists must recover—are vanishing without a trace. Seoul Unit 5, having discovered that cases of Pixelation increase in every location where an echo disappears, begins to track who is taking the echoes and for what purpose.
Nam Haeon, the courier who runs across rooftops; Won Gyeongwon, the guide for lost emotions; Ju Hyeonrok, the excavator of solidified memories; and Yeon Hwi, the collector of fading light. Before these four, who chase the same incident through different eyes, you—a stranger—suddenly appear.
Together, the five of you navigate the rooftops, alleys, and long-abandoned places of Seoul marked with black pins, chasing the whereabouts of the missing echoes. However, as they draw closer to the truth, it is not just the culprit's traces they face. Memories they tried not to see, hearts they gave up on understanding, and fears hidden behind smiles and silence also reveal themselves one by one.
Against a world that erases everything except what it wants to see, the five chase the secrets of the missing echoes and the black pins.
Can they truly look at the same world even with different resolutions?




On the office wall of Seoul Unit 5 of the Echoists hung a large map of Seoul. White pins were placed where echoes were discovered, and colored threads of the responsible unit were hung after recovery. Black pins represented locations where the echo had vanished before the Echoists arrived.
At first, these were considered cases of missed recovery timing. However, as the same thing repeated across Seoul starting a month ago, the number of black pins continued to grow. Even when echoes naturally scatter, they leave traces like faint light or vibrations, but in the places with black pins, even such things were not found. Furthermore, Pixelation phenomena followed in every area where an echo disappeared. While there was no evidence yet to prove the relationship between the two phenomena, it was difficult to explain unless someone knew the location and recovery time of the echoes in advance and even swept away the traces. The Seoul Branch eventually began investigating the increasing black pins and Pixelation as a single case.
Hyeonrok was checking the echo disappearance points and Pixelation outbreak areas displayed on three monitors. Haeon, glancing at the map, quickly noticed a newly placed black pin. He wasn't particularly pleased by the fact that he noticed changes on a map so well while frequently missing people's faces.
Gyeongwon pulled the bandage a bit tight. He had scraped his palm on a railing while checking a rooftop he didn't usually use after receiving word that an echo had vanished. Haeon watched Gyeongwon's face more than his hand and slunk back behind the sofa.
"I arrived so fast I didn't have time to call."
7 minutes until the scheduled arrival time. I ran to the edge of the rooftop, deviating from the set path. Below the building, pipes, signs, and old outdoor units were tangled together. Placing a foot on the railing, I mentally traced the sequence. Pipe, red sign, opposite rooftop. It'll take 5 minutes. What if my foot slips? That's something for the future me to handle after slipping. As I tightened my bag straps, Gyeongwon's voice came through the radio. Before he could even finish telling me to take the safe way back, I had already thrown myself into the air. The echo in the bag was a heart that had already failed to be delivered on time once. I couldn't let it be late twice.
"Got it~ I'll go safely. Though my definition of safety might be a bit different from yours!"
The client said three times that no emotions remained now. The second time, they fidgeted with their fingers, and the third time, their voice cracked at the word 'no.' It wasn't that I didn't believe their words of being okay, but I decided not to end it with just those words. 'Do you hate that man?' I was about to ask that but kept my mouth shut. The moment I called it 'hate' first, the client would be dragged toward that name. Without rushing, I pushed the empty chair opposite slightly back. It was a sign that they didn't have to answer right away. After a long while, when the client was about to say they were okay again, I asked two different things.
"Do you regret hating him, or does the fact that you still hate him cause you pain?"
I saw the half-torn demolition notice before the Echo Stone placed in the middle of the alley. The painted-over house number and the scratches on the threshold from dragging furniture out multiple times were also different from what I read in the post. A neighborhood the residents left voluntarily? I opened my laptop and found the article again stating that compensation negotiations had failed three times. I drew two lines through the hypothesis I had built until a moment ago without regret. But when a colleague tried to pick up the Echo Stone, Hyeonrok urgently grabbed their wrist. Taking just the stone would end the investigation quickly and make the report clean. It was so clean it was a problem.
"Wait, don't take it yet. If we just look at the stone after cutting out all the context, there's no point in us being here."
I thought there would be no light to take from the abandoned school on a cloudy day. While walking through the empty classrooms, I stopped at the third window. Sunlight between the clouds was illuminating a name scratched onto a desk. The light was faint and not even enough to fill a single bottle, but it didn't leave the spot, as if it were alone reading a name that no one seeks. I brought the masking tape over the light. Every time the tape got closer, the shadow of my hand covered the name, and the light and letters vanished together. When I withdrew my hand, the name reappeared. I reached out once more but stopped at the same spot. If I take all the light, the name becomes letters that no one reads again. Yet if I leave it as it is, it will disappear when the clouds close. I carefully gathered only the edges into a small bottle. On the label, I wrote 'Third window, cloudy' instead of a date. Only after confirming that the remaining light settled back onto the name did I close the bottle cap.
Pixelation was different from a disease where vision deteriorates. Even if it was right in front of me, the form simplified the moment I considered it unimportant. Passersby's faces were left with only the positions of eyes and mouths, and building windows were reduced to a few neat squares. Looking for a long time didn't always make things clear. Without the heart wanting to know, it wasn't visible no matter how close it was. They say the joy of getting to know someone isn't in something new appearing, but in belatedly discovering something that was always by your side. Pixelation took away those discoveries one by one. I memorized people's clothing and voices instead. Even if I got a name wrong occasionally, if I smiled first, most people smiled back. Only Haeon knew what it was he had laughed off.
