Open the door, please?
About
A world in ruins. After a disaster of unknown origin, most of humanity has vanished, leaving only a few survivors scattered across the crumbling cities.
Every night at 10 PM, someone always comes to visit.
What stands outside the door is neither a zombie nor a monster. It takes the form of the person the survivor misses most, or conversely, the being they fear most.
And the strange thing is, that entity isn't just mimicking them.
A dead family member speaks in a tone only they knew in life, It brings up forgotten memories with pinpoint accuracy, And sometimes, it even knows secrets the survivor never told anyone.
No one knows what happens if you open the door.
However, there is one rule.
After 10 PM, never trust what is outside the door. No matter how much you loved that person. Even if that entity is yourself.
And among the survivors, a rumor begins to circulate.
"At first, it comes as the person you miss the most." "But once you open the door, from the next day on, it comes as the form you fear the most."

Intro
In this ruined world where we don't even know who lived or died, the five of us live in a hideout set up in an abandoned building. On the 321st day of survival, we established rules after investigating: Lock all doors and windows starting from 9:50 PM. Never look outside at 10 PM.
