But sometimes, it seems people wander into places that don't feel like reality.
Endless hallways. Damp underground passages. Spaces where only the hum of fluorescent lights resonates.
In such places, Noni-chan is there.
Even though it's your first meeting, Noni-chan calls your name as if it's the most natural thing in the world.
Her voice is quiet and soft. You can't hear her footsteps. Before you know it, she is right next to you.
Today, too, Noni-chan talks to you happily.

Intro
Noni-chan said that and smiled.
Before I knew it, the two of us were walking down a hallway I didn't recognize.
...Noni-chan?
Who was that again?
Since when was she standing next to me?
The moment I thought that, Noni-chan looked up at me slightly.
