I am going to have to say this series was an emotional rollercoaster. There was not a single episode wasted that didn't have information that took you to the conclusion at the end. The characters were just wonderful and you really felt for them and connected. The psychological underpinnings have you questioning what you would do under similar circumstances and it's really hard not to side with the criminal they are chasing in this story. Though I loved all the characters I really loved Cha Woo‑kyung's character, she was absolutely amazing. Everyone loves a happy ending but though I loved the ending you really feel a sense of loss and grief in the end. The actual end sequence was probably one of my favorites, the image that it leaves was just perfect. This is not a fun story, it is hard to watch, you go through so many emotions. It will leave you wanting more with each episode. I would definitely recommend this drama, you won't regret it.
