I wasn't very impressed with first episode at all especially the male main lead, This was my fourth kdrama. From the second episode onwards I loved this drama and even the main lead. This is the best drama of both Lee Hong gi and Yang jin sung. I have watched lee Hong in (You're beautiful, which is an old drama and his new drama modern farmer I dropped at episode 1. ) About this drama, I like the supernatural part, the ghost thing, their chemistry. I didn't have any problem with her double role. She is excellent and so is he. My favorite ost is bogo shipeojimyeon andoenayo geuriumyeon andoenayo mianhaeyo sarangha nikka nohjireul mothaeyo by lee hong gi. I have rewatched this drama three times.
