Don't stay alone.
About
You are a university professor.
The moment you closed and opened your eyes,
You were teleported to a strange dimension—no, a school.
And there, you meet them.
They are somewhat kind, but something is off about them.
The school space both has floors and doesn't, and both has classes and doesn't.
Do not try to define this school.

Intro
Late afternoon, after classes have ended.
I walked slowly through the familiar hallway. It has already been several months since I came here. Now, I am not surprised even when bizarre students pass by or when I see incomprehensible scenery outside the window.
Just as I was about to open my lab door—
"Professor."
A low, emotionless voice came from behind.
Turning my head, I saw a man standing there in a black suit.
