🚇 𝑯𝒂𝒏 𝑴𝒖𝒚𝒆𝒐𝒏 ── Han Muyeon

Name │ Han Muyeon Aliases │ "Station Agent of the Non-Existent Station" · "The Man of the Display Board" · "The Lost Station Agent" Classification │ Bongwol Station Anomaly / Non-human Location │ Bongwol Station Underground Platform · Non-existent Platform

『There is a station at Bongwol Station that does not exist, and one station agent is always standing there.』

He takes the form of a young man in a black station agent uniform, but in the place where a face should be, a single black display board is embedded.

Train arrival times are not displayed on the board. Instead, for every person who faces Han Muyeon, the name of the place they wanted to go most appears in red letters.

Fine lines like subway maps run across his neck and the backs of his hands, and station nameplates for stations that don't exist in Bongwol Station are attached all over his uniform.

Han Muyeon always gives directions kindly.

"It is this way."

However, the path he guides you through is strange. It is clearly a passage that was inside Bongwol Station, but the further you walk, the more unfamiliar the station names and routes become, until you eventually arrive at a platform that does not exist in reality.

⚠️ 𝑹𝒖𝒍𝒆𝒔

➤ Do not tell Han Muyeon your destination.

➤ If your name appears on the display board, never follow it.

➤ Even if he guides you saying, "It is this way," do not follow behind him.

☇ If you break the rules, your name and the word 'Arrived' appear on the display board instead of a destination. From that moment on, all signs in Bongwol Station change to the direction Han Muyeon points, and the original exit disappears.

🚉 𝑪𝒉𝒂𝒆 𝑺𝒆𝒖𝒏𝒈𝒉𝒘𝒂𝒏 ── Chae Seunghwan

Name │ Chae Seunghwan Aliases │ "Passenger of Platform 7" · "Child of the Non-Existent Platform" · "The Seventh Passenger" Classification │ Bongwol Station Anomaly / Non-human Location │ Bongwol Station Underground Platform · Non-existent Platform 7

『Bongwol Station only goes up to Platform 6. However, at 1:11 AM, a door opens for someone at Platform 7.』

He takes the form of a young man with black hair, but traces of the subway are attached to his body in distorted forms.

The most striking feature is the old '7' platform sign embedded in the center of his chest. The sign is dug into his body like flesh, and every time the number 7 flickers faintly, a vibration as if a train is entering is felt nearby.

One of his eyes is that of a normal human, but the other glows with a red light like a train's destination display board.

Subway maps run like veins along his nape and arms, and his fingertips are split thin and long like the gaps in platform screen doors.

Skin with the texture of train seat fabric is revealed beneath his black passenger clothes, and a low vibration, like a train running in the distance, sounds whenever he moves his body.

Most strange of all is his shadow.

Chae Seunghwan's shadow always takes the form of a person sitting inside a train.

He does not speak to anyone. He simply stares at the empty tracks, waiting for the train he is to board.

And when it becomes 1:11 AM, a train arrives at the non-existent Platform 7.

⚠️ 𝑹𝒖𝒍𝒆𝒔

➤ Do not try to find Platform 7 at Bongwol Station.

➤ Do not ask Chae Seunghwan, "When is the train coming?"

➤ Even if a train arrives at Platform 7, never board it.

☇ If you break the rules, Chae Seunghwan turns his head for the first time. The passenger's name and seat number appear in his display-like eye, and a train door that was nowhere to be found opens. From that moment on, that person's shadow changes into a 'Passenger of Platform 7' just like Chae Seunghwan.

⏳ 𝑬𝒕𝒉𝒂𝒏 ── Ethan

Name │ Ethan Aliases │ "The Backward-Running Train" · "The Regressive Engineer" · "The One Who Carries the Past" Classification │ Bongwol Station Anomaly / Non-human Location │ Tracks · Engine Room · Platform after service ends

『If you encounter a train moving backward.』

He takes the form of a young man in an engineer's uniform, but every phenomenon occurring around him moves in the opposite direction of normal.

His black hair, uniform, and tie flow against the direction the train is running, and the second hand of the watch on his wrist moves backward. The eyes and mouth on his face are subtly flipped left-to-right, and an old clock moving in reverse is embedded in the center of his chest.

Faint traces of his childhood body appear overlapping his current form in various places. Every time Ethan takes a step, the surrounding time flows backward for a moment; dropped objects return from the floor to the hand, and closed doors open again, as everything nearby returns to a past state.

The train Ethan drives has no fixed destination.

The train appears to be running forward, but where it is actually heading is a single moment in the past that the passenger regrets most.

And the person who gets off the train realizes that they have returned to that moment.

⚠️ 𝑹𝒖𝒍𝒆𝒔

➤ Do not ask Ethan for the current time.

➤ If the train begins to reverse, do not look out the window.

➤ Even if you discover your past self, never speak to them.

☇ If you break the rules, the train's time begins to flow completely backward. The passenger's memories and appearance gradually revert to the past, eventually turning into a child who cannot remember their current self.

Ethan seats the passenger who has changed like that in the empty seat at the very back of the engine room.

And then he starts the train again.

📢 𝑺𝒊𝒆𝒍 ── Siel

Name │ Siel Aliases │ "Announcement After the Last Train" · "The One Who Broadcasts" · "The Eye That Sees the Station" Classification │ Bongwol Station Anomaly / Non-human Location │ Announcement Room · CCTV Room · Station after the last train

『If you hear an announcement after the last train has left, it is not a broadcast for the passengers.』

A young male non-human who seems to be the station announcement system made flesh.

Instead of a face, a massive subway speaker is attached, and numerous broadcasting cables are connected to his neck and chest like veins.

From the place where a mouth should be, a mix of station announcements and human voices flows out, and in the two small display boards that sit in place of eyes, CCTV footage from inside Bongwol Station is displayed in real-time.

Small CCTVs are embedded all over Siel's body. The screens show every single person currently in Bongwol Station without exception.

However, sometimes people who do not currently exist in the station appear on the screens.

Siel continues to make announcements even after the last train has left.

And when the final broadcast ends, he calls out the names of the passengers inside the station one by one in a very small voice.

⚠️ 𝑹𝒖𝒍𝒆𝒔

➤ Do not respond to your name heard after the last train.

➤ Do not look for your own image within the CCTV screens.

➤ If Siel says, "Passengers, I will perform a final check," leave the station immediately.

☇ If you break the rules, all announcements stop simultaneously. And every CCTV screen in Bongwol Station begins to show only one person.

The self on the screen moves a few seconds ahead of the actual person.

The moment the self on the screen slowly turns its head to look at the camera, the person who was inside the station disappears.

From that moment on, that person exists only within the CCTV screens.
