It seems I'm one of a few who didn't enjoy the drama as much as I'd have liked to.  The drama is shot beautifully and everything looks cool and slick. Park Hae Jin was an excellent choice, as was the villain and sidecharacters.

My issue is that it focused 30% of its story on a romance that appeared out of thin air. I never connected with them as a couple in love and never really understood why Agent K would fall for this particular woman. Strangely, I don't dislike the female character, I just do not see any chemistry and missed out on the leading-up-to the romance.

I will talk about it more below, but I want to intersect by saying: this is still a good drama to watch for action fans. Just ignore the romance and you'll be fine. The rest all works very well. The humor isn't making anything ridiculous and the action is fastpaced and cool. Definitely a drama I would want to use in a youtube edit. It's just not at all a romance drama.

Near the middle, roles have been assigned and some secrets have been revealed, and Agent K reveals part of his identity to save the girl he - apparently? - likes. However, I don't know if he really does, or if it leads up to a bigger plan by then. Maybe Park Haejin wasnt allowed to display hearteyes? Maybe the writer focused so much on making the action drama well thought out and only decided to add romance (to please more people) near the end so it wasnt fleshed out. Either way, I don't connect with it at all. I can understand the trope and I would have loved it if it was written better but in this case I don't see how she goes from "who is this dude" to "let me hold your hand and love you forever".  Everything sure does look good though. (Except the girl's hair. Why oh why would you do that)
