If this is true... I suddenly got flashbacks of Hidden Identity which was just a waste of potential. Also, there hasn't been any other substantial names attached or dates given about the drama, so it is possible that Park Sung-woong might not join in the end. Well, the only good news is that the original was good and OCN tends to be better at police and noir-ish dramas than TVN. But after Signal, that might not be the case anymore. For Park Sung-woong's sake, I do hope the second season will be decent.
