This is my top 2 Kdrama of all time behind Dr.Romantic.
This Kdrama is super good that every ending of 20 episodes will make you watch another one?.I love the whole cast,thanks to them they gave us a whole new amazing story. I recommend that everyone should watch this especiially if they watched serial killers documentary,this Kdrama has it! I love this Kdrama even it has no good music that I like and that's how I love this Kdrama. In terms of rewatching it I will say that 40% possibility that I will rewatch it because there is no mystery and guessing what will happen next in the story.
