I watched it quickly and I really liked it. Action, fight scenes, photos, music too. Koreans and Poles, we have a similar history, with many years of periods in which our neighbors tried to erase us from the map of the earth. Maybe that's why I watched with compassion and understanding.
The first main role for me is Lee Ho Jung, she is simply brilliant!!! It's worth watching the entire drama to see the scenes with Lee Ho Jung - there are of course a lot of them.
I was amazed by her talent, ability to use facial expression, perfect use of voice with nuances of tone, and acting at the highest level. And of course, well-played action scenes. The conversations between the paid assassin and her target are fascinating, thanks to the acting of both of them, but they also had a very well-written script. The plot of the evolution of the relationship between the paid killer and the target from episode to episode is cleverly presented.
Blood flows in streams and gushes, but mainly the invaders die :), which is comforting :).
