The highlight of this show was definitely the action scenes. They were very well choreographed and not overdramatized too much by like climbing up walls and stuff like that. The acting was fantastic, especially from our main character Jung Ji Ahn (Kim Hye Joon). Every single one of the side characters absolutely nailed their roles as well. I felt like there was no wasted time or filler episodes in this show, very important for an 8-episode long series. This was a very solid action show, and if you are into bloody fight scenes and drama, this is for you!
