塞がれた声 (MIRA文庫)

The chaos of Black Friday adds a unique tension to the story, but I'm curious whether that setting was planned from the start or evolved during writing.

The story picked up speed, but I wondered if that was a deliberate choice to build suspense or just the natural flow of the plot.

Understanding the motivations behind the villain added depth, and I'm curious about the research or ideas that shaped that character.
