First and foremost, the setting was settled for sure. Church and Hospital are deeply connected if you look at it closely. As said in the drama, both Priests and Doctors also serve the ill, whether it is illness or demon. This drama was not totally horror but had a bit of everything, romance, comedy, action, melodrama. I had my doubts that I'd dream about ghosts, but this drama gave me a bigger thing to worry about than the ghosts. I can't believe the ending. I was so happy and set to have #EunMin to have a happy ending, but everything turned out to be a subconscious dream. I was so sad, utterly. But what could've been done, it was the Screenwriter's plan all along. I desperately wanted a happy ending for them and all the couples mentioned in this drama. This would've been elite then. And I still couldn't figure out the spirit, Samael's motive. Why did he do that? What was the story behind him becoming evil? Why was he in hospital clothes and what the hell happened to his face? Those questions were left unanswered, unfortunately. Rest, the drama was killer.
Still, I was hoping for Ham Eun Ho and Oh Soo Min to end up together. They did end up together though, even if it was not in the way I wanted. It was better than dying, though.
