This drama was a fun combination of thriller/ghost horror and poor gal gets saved by rich, mean guy. Gong Hyo Jin did a fantastic job bringing Tae Gong Shil's insecurities and fears to life while standing up for herself when people treated her poorly. I enjoyed the way in which she was learning to live with ghosts and strive make her life better.

However (and I know this will be an unpopular opinion), I felt So Ji Sub's performance lacked depth and dimension. He seemed to be the same person throughout the drama, never getting to actually show his transformation.

There is a major flaw in this drama that happens near the end. The characters act completely out of the norm of what you have seen throughout the show. This threw me off. Furthermore, the dramatic revelation and story about Joong Won's deceased lover was told in a sloppy and confusing way, and I barely cared about it. Those flaws are things I cannot overlook. The time used around these parts could have been executed differently in a way that grew the relationship between the main leads, but it didn't seem to do that.
