This drama was very enjoyable. A lot of it is a very typical ghost drama plotline, there is not anything very unique about the plot. But in many episodes I found that the writing was very well polished, an attention to detail that many dramas do not have. Many dramas just force in a trope even when it does not make sense, but this show seemed to care that everything makes sense. The twists and emotional arcs are very well thought out. The performances are also very good. The side stories are especially rich.

One criticism is that the final arc has some odd pacing. I am not sure if it was "bad" pacing, but they make some strange choices to reveal things before going back and showing stuff leading up to it. In a way, a lot of surprises are not a surprise because they show you the reveals so early before building up the tension. I am not sure if those were bad decisions, but I would say this is not a drama where you will be guessing a lot. There is some suspense, but it is pretty light.
