If you not sure what to do with this drama.... just watch it and you shall like it! What I liked?..... chemistry between main leads, OST, funny and sad plots, also, the ghost girl was super funny at the begging, and of course the fact that the drama did not drag for 20 more episodes. Disliked? Story line was fine, but the not the best with some flaws, and a little boredom from time to time. Honestly, the series would be a total disaster if not for main actors and their great chemistry. After watching Master's Sun this was not as good, but enjoyable because of paranormal theme. I would recommend people to watch it. It was entertaining, and really funny at times. I did not cry much, perhaps once towards the last episode. Ending was rushed, but satisfactory. As for rewatch factor... I would say perhaps in the future, but not now.
