Was There a B1 Floor

Was There a B1 Floor explores the unsettling feeling of discovering something impossible inside a place you know by heart.

Returning from a business trip late at night, the protagonist notices a mysterious B1 button inside a familiar station elevator. By the next morning, it is gone.

Was it exhaustion, a dream, or something that briefly existed and disappeared.

Blending station announcements, elevator sounds, and hazy city memories, the song captures a small crack in everyday reality and turns it into a lingering urban mystery.
