Bad bad bad acting from the FL.s. Lee Chung Ah's acting was slightly better than the seol hyun's but still leaves much to be desired. Which is strange because I watched a movie with seol hyun in it but she was decent in that movie so i'm not sure whats up in this drama. In theory the story sounds interesting but I read ahead and decided to drop it after I saw it was going to turn into sci-fi. If you do not mind the sci fi angle and sub-par acting you can consider this drama, though there are many other similar alternatives out there.
