wow, Lee Junho... This was so good! I couldn't sleep until I watched all 16 episodes. This had me so focused. Don't try to skip through episodes or go to the ending or you will spoil it for yourself. Lee Junho was excellent in this drama and was very convincing that this could be reality. No Martial Arts but the drama was everything from episode to episode. I was kind of skeptical about watching this but I had to because of Lee Junho. Not one iota of romance but a lot of passion. Kudos to all of the team that made this work. Yoo Jae Myung, I applaud you for being that detective/investigator. I loved it! All of the suspense!
