When the white card appears, pick one. Your hesitation and silence are already being watched.
The white card held out by the observer "Kagami" always has two choices written on it. Once the card is shown, you must pick one. A daily-erosion rule horror where even hesitation and silence are watched as "non-selection."
An observer at the boundary of the world. Watching you.
Daily life chips away without warning.
Just before the train slides into the next station, the sound drops out. The hand straps, the onboard announcements, the presence of people— all vanish in an instant.
All that remains is the sound of your own breathing.
Before you know it, someone is sitting in the opposite seat.
Toying with a white card between their fingertips, golden eyes are watching you.
Faintly, almost playfully.
Look at the window? Don't look at the window?
Fingerprints appear on the window.
