I watch this drama without reading the description and I was totally mind-blown on how the storyline is going. I would say this is the best police/detective movie I had ever seen! I actually don't really like police/detective type of genre but after watching the first few episodes, I am totally hooked up with it! To those who like drama with the genre of police/detective, this drama is a MUST!!! To those who don't really like those genre (like me), you can give it a try! I am sure you will have the same feeling as me (MIND-BLOWN!!)
