I came here misled by the cover, believing this was going to be a romance with some touches of drama, but it turned out to be almost a completely action series. What started as a nice romance at first glance then became something almost nonexistent within the series; if they dedicated 3 minutes to a romantic scene in the episode, that was a lot, and those were the only minutes in the episode where the female lead appeared. I was really enjoying the first few episodes, but then it became increasingly tedious, with more and more unnecessary scenes that, if removed, would have made it much more interesting. The series could have been really good if it had fewer episodes and better romantic development. If you're looking to watch a romance story, this is not for you, as after the first episodes they completely forget about it.
Note: MyDramaList should include Action among the genres so that people come prepared, at least.
