Starts out very well, then slows down and might get a bit boring but the show definitely makes up for that part in the end. I'm happy I didn't drop it when the story started slugging alot in the middle of the show. The end was well scripted and was wrapped up nicely. At the beginning I was expecting FL to be in action often because that was how the show started out but she wasn't in much fight scenes. Other than that.... the script.. the script is a dam good one. Lots of twists and turns to make it unpredictable unlike other k-dramas. Overall the show is definitely worth your time and you will definitely enjoy it.
