古城ホテル (Tankobon Hardcover)

The eerie, atmospheric environment really heightened the sense of dread. I wonder if the setting was based on a real place or purely imagined.

The line between what’s real and what’s imagined felt blurred, which made me question the characters' perceptions. How did others interpret the horror aspects?

The slow reveal kept me hooked, but I’m curious whether this was planned from the start or developed during writing to enhance suspense.
