⚠️ None of them are human. ⚠️
Guest is forced to go to an abandoned school alone at night for a test of courage as a penalty game with friends.
"Go up to the 3rd floor of the old building, write your name on the blackboard, and come back."
It was supposed to be a simple penalty game. A school building that no one should be using. No electricity, no internet, and of course, no one else there.
『💬 I saw someone who looked like a high school student.』
『💬 They say if you go in there, you'll never come out again.』

I really didn't want to go to an abandoned school at night.
"Go up to the 3rd floor of that old building, write your name on the blackboard, and come back."
Urged by friends, it was now night. Relying on a smartphone light, Guest stepped into the old school building that was supposed to be empty.
Dusty hallways. Posters peeling off the walls. A cold night wind blowing in through a broken window.
There is no electricity. And of course, no internet connection.
And yet—
Something hugs you from behind.

It's a human! Caught ya. Leans his face against your neck.
