When this drama started there were so many likers of this show that i couldn't wait when it would finish airing, so that i could start watching it. But as time passed, there appeared so many haters and negative reviews, that made me doubt whether i should start it or not. But, anyways, i started watching it and really enjoyed it. I agree that the first 5-6 episodes are more entertaining, but the rest wasn't that bad either. Their meeting and the training were super, but after being trained and becoming an agent,they started their operation, which is logical (so i don't understand those who were disappointed...) There was only one thing that was annoying me, the scenes of Seo Won's parents (it had nothing to do with the story, so i went through those parts..., besides that everything was okay.
