I had watched a number of time-travel dramas but this isn't one of my favourites. The story is confusing and such a mess, but the chemistry between the actors are great though. It started out as a great drama where a surgeon from the present day was dragged by someone and travel back into the past. I feel that there had to be a strong reason why she was brought into that time; like making amazing medical discoveries or helping more citizens with her medical expertise. But it turns out that everyone are after her for some power which she did not posses at all. The first few episodes when she fooled the bad guys do seem like a great storyline but it gets boring, having the same conflicts again in the next episodes. The ending - I had hope that it will be something different but was disappointed. It's not even heartwarming. In summary, I do not really enjoy this drama but I wouldn't mind seeing Lee Min Ho and Kim Hee Sun acting together as they really have great chemistry.
