Trzy sypialnie, jeden trup

The cozy atmosphere is so vivid—did the author base it on a particular place or community, or did it evolve from the story's needs?

Some personalities felt larger-than-life, but it added to the cozy vibe. Were these traits intentional to keep the tone light and fun?

The tone shifts felt seamless, but I'm curious whether humor was always meant to be a key part of the story or if it developed during writing.
