Well, I only started this drama because the actors and actresses, Jang Na-ra and Seo In-guk, not to mention Do Kyungsoo. They were all great at acting and their acting never disappointed me. I also was introduced to Park Bo-gum. He is a great actor and I now feel like watching all his movies and dramas. Actually, I figured out he was in a movie I already had watched, ''Blind''. I should point out for those of you watching this for Do Kyungsoo, it is really not worth it. Please just find clips on youtube. He is the murderer evil bad guy, but, he only plays the younger version of this guy and the flashbacks only happen ever so often. That being said, if you want to see great actors and several murder cases this is the drama to watch. The story line and characters reminded me several times of a combination between the dramas, I can Hear your voice, You're all surrounded, and Pinocchio. But, with a less satisfying ending then all three of these dramas. I was really upset with the ending. I found it not really that great, and some of the story lines were not closed that well. If you are able to ignore the ending or imagine it ended similar to I can hear your voice, then I suggest watching this drama. Bromance is awesome in this drama and literally everywhere. Which helped a great deal because the romance was quite lacking. Humor came and went, but, this drama in general is not really all that funny. It has a lot of serious moments and for any viewers that hate blood or dead people this drama is not for you. Except for a couple episodes I would not waste my time rewatching this drama. So, for the most part I only liked the Bromance in this drama.
