I seriously love this drama! The suspense and mystery is just too awesome!! The story line is great because it doesn't rush right into each case but builds it up. I love how the first 2 episodes were about how season 1 ended (well of course that is normal for a sequel). One thing i liked about it was that they didn't rush right into it, but build it up and showed it over 2 episodes rather than 1. Also each case was just as suspenseful as the previous one. The ending was just amazing, and like the beginning the last case was split into 2 episodes! They put some serious thought into this! Can i just say i love this cast, seriously i don't think i can ask for any better cast members for this drama. Every actor portrayed their character soo well. Joo Sang Wook as Yeo Ji Hoon was just awesome! I loved how his character was hard to figure out because at the beginning you get mixed feelings about him but then as you understand what is going on you can't help it but to love him! One thing i really liked about him was how he became more casual-looking near the end, and that he became closer to his team! One thing i really liked about his character was that he kept me on my toes for the first 2 episodes because his character was seriously hard for me to figure out. But ones i understood his character i ended up loving him more haha Jo An as Nam Ye Ri was great! i really loved how her style of clothing changed in this season. She looked gorgeous and stylish as well as tough and had the you-don't-want-to-mess-with-me vibe going on. I really liked how her character developed from being a damsel in distress to an amazing officer! I really hoped for Nam Ye Ri to end up with Yeo Ji Woon >.> seriously i wanted more romance between these two Dx (then again it is a crime drama so =/ ) Kim Sang Ho as Baek Do Sik and Choi Woo Sik as Park Min Ho were just great! i loved the random comedy factor that these two portrayed.. though i can't really call it 'comedy' but their relationship made me smile soo much! I love Choi Woo Sik as Park Min Ho, i don't think anyone could have portrayed this character any better! He was just too awesome and funny! I love Woo Sik *.* I really liked the ost, though there was really just one song, it was still really good because it had that mystery feel to it, which fit totally in with the drama. If i had to choose which season had a better ost then, i think i like the 1st season's sound track more.. That doesn't mean i don't like this season's sound track.. I just prefer season one ost. But i love both songs! I gave the rewatch value 9/10, which is pretty high, but that is because i don't think i would get bored watching it again, especially Joo Sang Wook's character, he was a mystery to figure out plus i love mystery/crime dramas a lot so i would rewatch it anyways. Also i think i would go over the same feelings and questions over in my mind while watching it again.. especially the ending. Seriously i think i will have to watch the last part of the last episodes over again in order to grasp what is going on xD Overall, i gave it a 9/10 because i think this is an excellent crime/mystery drama, every episode was great, especially the ending was just too awesome!! Like the 1st season, this season ended with a cliffhanger, suggesting to me that there is definitely going to be a 3rd season!! I can't wait for it *.* I hope they will keep the casting the same because i don't think i can handle a different casting for this drama! Guess we will see what is gonna happen next! So if you love mystery/crime/investigation dramas then i recommend you to to watch this drama! You won't be disappointed :)
