You don’t have to believe in ghost, you just have to believe in the world created in this series where ghosts exist. The tension is a fight against evil. This series adds some imaginative premises of how the natural and extra-natural worlds relate to one another. Once you adopt their premises, it settles into an intriguing and thrilling drama. Once again, I’m following Park Eun-bin’s filmography, and, unsurprisingly, she creates a fully realized character. I love how each of her characters are so distinct from each other, yet genuine to the project. She won’t be losing this fan. I give this series a 7 (good thriller) out of 10.
