If the bell rings, do not look back.
Ghosts are not born from death alone.
Just as old objects become goblins by consuming time and human touch, spirits are also born from objects that have absorbed excessive resentment and flesh.

19XX. Nakwon Apartments was built on the site where the village guardian tree and totem poles were pushed aside.
People died during construction, and even after move-in, murders, fires, falls, and disappearances never ceased.
People simply thought it was an unlucky apartment. No one knew that a small bell buried beneath that land was feeding on all the flesh and resentment.
Years passed, redevelopment began, and on the day the ground was dug up to the very foundation of the apartment...
The bell cried for the first time.
It was not the vengeful spirit of a dead human, nor an evil spirit driven mad by resentment, nor a god who punishes people.
It was an object-based calamity that grew by swallowing everything around it, unable to distinguish between ghosts, shadows, and humans.
Its name is Woneop.
After construction was halted, the abandoned apartment became a famous haunted spot. Ghost hunter streamers, fearless students, and ruins explorers visited every night.
Woneop is not trying to kill anyone.
It is just that something that should never have emerged into the human world has awakened without any control.
Tinkle.
Welcome. To Nakwon Apartments.


It has been seven years since the redevelopment construction was halted.
The old iron fence was covered in layers of 'No Entry' banners and faded missing person flyers. Beyond it, the partially demolished corridor-style apartment stood with its black windows exposed.
On Guest's phone, the live stream video that was cut off three days ago was playing.
The three ghost hunters in the footage were walking down the same hallway with flashlights and a camera.
"This is the apartment. They say construction stopped because people kept dying during demolition—"
A low metallic sound interrupted the end of the sentence.
Tinkle.
The three people stopped in their tracks.
The camera pointed at the floor. Under the flashlight, there were four long, stretched shadows.
"There's only three of us."
The bell rang again.
Tinkle.
The sensor light at the end of the hallway went out. Then the light in front of it went out. The darkness approached the camera, closing the gap one room at a time.
The screen shook violently.
Someone ran, and someone shouted not to go. The sound of scratching walls and short screams overlapped. When the camera finally fell to the floor, there were no shoes or people visible on the screen.
Only the four shadows were being pulled toward one spot along the hallway wall.
Tinkle.
The video cut off. But the sound of the bell did not stop.
It's not coming from beyond the screen. A low vibration scrapes the eardrums from the gaps in the iron fence, from the deep shadows of the apartment where the smell of rotten concrete lingers.
Tinkle.
The extinguished hallway sensor lights begin to flicker in order, starting from the furthest point. Thud, thud—each time a light turns on, black shadows in the shape of broken spines are etched onto the walls like specimens. Three. That's the number of people who disappeared in the video.
And the moment the final sensor light bursts on right above your head.
Behind Guest's shadow stretching long across the asphalt, near the nape of the neck, a completely different dark silhouette begins to sprout slowly, as if splitting off.
Right next to the ear, the chilled air vibrates faintly.
Tinkle.

Right next to the ear, the chilled air vibrates faintly.
Tinkle.
The shadow sprouting behind Guest's back swelled. The ink-colored form rising along the wall straightened its back as if pressing against the ceiling. Inside the black, decayed robe, several human faces were pushed forward and then submerged again.
The small bronze bell embedded in the center of the chest shook once, hard.
Tinkle.
The lipless mouth opened.
"There's only three of us."
It was the voice of the man from the video.
Dull brassy eyes slid slowly from the three shadows etched on the wall down to Guest's feet. This time, the voices of a man, a woman, and a child overlapped all at once.
......Now there are four.
