I liked the concept of this one. I Love when there's characters swap and Yang Jin Sung does a great job at playing both characters. I also like the fantasy level of this show with the spirit of the 1st wife haunting all the others and of course I liked the love story. I liked that she made him less cold and he made her less simple. All that said the key things I did not care for in this were just an overall feeling that it was a little too played out. While Jin Sung did well at portraying the two separate women I don't think the rest of the characters really clicked for me and the whole mystical fantasy part got a little too convoluted. I wish it had been simplified.
