I was encouraged to watch this drama because it was well-received and got a lot of appreciation from the viewers that I personally stood correctly. I must say the plot was cleverly presented, every turn of events has surprising elements, and the revelation of the mystery itself though dragging the story long did not bore me at all. Watching this drama made me a smart viewer because as the male lead went on his personal investigation, I myself was thinking along with him. It was a surprise that each protagonist and antagonist has his/her own wittiness to beat one another. However, the male lead stood among the rest. His tame personality and well-behaved manner disguise his inner guts to fight and you will love the charm of his sarcasm while gently talking back to his superiors. This drama exhibited the importance of having great skills in the field of investigation as a prosecutor so that you don't have to solely rely on your working detectives to solve a crime and eventually serve justice uprightly. The only flaw I found in this drama was the scene of the high school students hanging out in the house where the murder crime happened, it was irrelevant and unnecessary to be included. But I have to note that the emotional scene of the culprit shedding tears was a stellar performance of all. As I myself experience to be entertained by this show, it has to be known that it was close to perfection in line with its genre.
