This show has a very unique story line I have not seen in other dramas, with curse and ghost blend altogether with not one but two villains. I am surprised the rating is not higher. Possibly because the mediocre acting of the leads, although actress Yan Jin Sung did a spectacular doppelganger roles as the bad Yi Kyung and the good Doo Rim. Unfortunately actor Lee Hong Ki could not deliver a natural tsundere, although ML supposedly falls for the FL at the first meeting. They don't have a strong chemistry despite of numerous kissing scenes. The beautiful, scary but hilarious ghost really spices up the drama.
