The first Korean drama I watched fully and oh lord it didn't dissapoint. I am a sucker for crime stories and this drama gave me exactly that. When you start watching this drama you slowly get to know the characters, you are starting to connect with them. And where more stories come in to play and when things are unraffeling you just want to keep watching and you want to know what will happen with them. Will they stay a strong group? Will they survive? Will they achieve their goals? It's a great action psychological drama !
