Kto mieszka za ścianą?

The story kept me guessing, and I loved how the clues were layered. I'm curious whether this was planned from the start or evolved during writing.

The characters’ decisions felt so complex and realistic, which made me question what I would have done in their place. Did others find themselves sympathizing with characters making questionable choices?

The story built tension steadily without dragging. I wonder if the author aimed for a specific rhythm to keep readers engaged throughout.
