No spoilers. The typical K Drama has a feel good wrap up ending. This one does not and that's ok. The screenwriters here could have taken the easy route and written a 'happy' ending but instead they wrote the right ending for these characters and this story. After the last reveal and you're faced with the finale and perhaps a little shock you'll appreciate what happens and why it had to be that way.

The series has its share of action and fight scenes but these never take over and dominate the story and character development. There are too many shows and movies where it feels like a little bit of story wrapped around overly complicated and drawn out action/fight scenes. There were a few isolated cases early on with a bit drawn out fight scenes but once the skills of the main protagonist are established his later performance is marked by efficiency.

The story stayed with me after the finale as I couldn't help but think about the characters and their choices.

Looking forward to rewatching this one.

I'm surprised these screenwriters don't have more credits given how well written this series turned out.
