This drama is amazing. I liked everything about it, and I personally like detective dramas, so if you are thinking whether to watch it or not, read first this: Reasons why you should watch You're all surrounded: #1 Cha Seung Won ahjussi and Lee Sung Gi (I mean who doesn't love them, righ?) ;) #2 The story is great! 4 rookies detectives enter a police station in Gangam and as they are learning how to become a professional detectives, Eun Dae Gu is slowly revealing the truth behind his mother's death. #3 Great pack of actors! As a loyal and a big fan of LSG once again he didn't disappoint me. He potrayed his role to perfection and I just love his teary eyes!^^ Cha Seung Won ahjussi is another + to this drama. He is an amazing actor and his reactions and laughs added a comedy part to this drama. I loved Go Ah Ra's acting and she is I can say BEAUTIFUL! (though this is my first time seeing her). The chemistry between the main leads is beautiful! I enjoyed in their romantic scenes ^_^ #4 It will keep you excited for every scene. Episodes 8-9 gets a little boring, but after it's taking an amazing and exciting ride. #5 The OSTs- Uh, I loved every of them. In a thrilling, romantic, sad scenes, every ost fitted perfectly. #6 If you like detectives dramas, you should give it a try!^^
