I am an avid fan of thrillers who is always in search for good drama. I got recommendation in reddit and I decided to watch. OMG it's amazing, first 2 episodes was a little bit slow and confusing and then the drama picks up like a jet. Every episode was made like an art, the investigation part, the characters was all carefully written. It was a unique experience to watch a crime investigation taking place in 80's like when there is not much source to easily get information. Jung Kyung Ho and Park Sung Woong are both my favourite actors and as usual they have nailed their role. Their bromance was really good. And I liked the ending, At first I found it confusing but rewatching the episode again I found to be very unique and happy ending. Please watch this drama, it deserves a lot of love !!!
