I was about to write a long and detailed review but after reading all the reviews here, I don't think I have anything to add. Just a few notes; I feel bad for Park Hye Ryun the writer as how evil she is to write such story specifically for the character of Han Ji Pyeong who actually the red line of the story itself. And how she fooled us in the first two episodes that this will be a good drama, turns out a flop. If you haven't seen this drama, don't bother, I said this to make your life peaceful. Thank me later.
