Okay, so 'My Divine Doll'... I had to double-check which one you meant because there are a few webnovels with similar names floating around, but I'm assuming you're talking about the one by Argentum on RoyalRoad or ScribbleHub, where the MC is a dollmaker whose creations start showing signs of their own will.
Yeah, the supernatural twist is absolutely there and it's pretty core to the plot, but it's more of a slow-burn reveal than an immediate 'boom, ghosts!' situation. The early chapters focus heavily on the intricate craft of dollmaking and the MC's strained relationships, which honestly had me wondering if it was just a drama about artistry. Then you get these little moments—a doll's head turning just beyond the corner of your eye, a finished piece seeming to watch the MC sleep, tools misplaced in ways that defy physics.
The twist isn't that the dolls are haunted by external spirits; it's that the MC's own repressed grief, guilt, and latent psychic energy are unconsciously imbuing the dolls with a fragmented semblance of life. It's less about traditional poltergeists and more about a form of psychic projection or tulpa creation, where the dolls become vessels for parts of the maker's soul they've tried to lock away. This gets really unsettling when a doll modeled after a deceased family member starts to develop its own contradictory memories.
The supernatural element creeps in at the edges of reality, making you question whether the MC is losing their mind or if something genuinely paranormal is awakening in the workshop. The ambiguity is handled really well for the first two volumes.
