First off... OUCH! This is the first Kdrama I have seen that has the protagonist die T.T

This is the first Kdrama I have seen with the least amount of episodes, yet packed with so much action! I truly enjoyed this series because it was a break from other Kdramas I usually see, but it caught my attention. As a result, I could be biased. However, I honestly enjoyed the mix of action scenes, and the case slowly unraveling. It was a good medley of suspense, thriller, action, and mystery.

This is the first Kdrama I have seen where the co-leads do not live happily ever after, so I'm not going to lie, that took me aback. I thought that Kim Soo-Hyun would just go to jail at the very most of be let off or escape at the very least. To see the protagonist and the side kick, Phillip, die was just a shock to me.

I agree with some of the viewers that there were some plot holes I disagreed with such as, how did Do Hyun-Jin know so quickly that Ko Hyeon Woo and Yoon Ji-Hye worked together and simply the client of Kim Soo-Hyun? Also, why was the door to Kim Soo-Hyun lair opened like that?!? Wouldn't he know better to close and lock it at all times? One more thing, if the father did not see Do Hyun-Jin as his daughter, why did he help her "remember" who her favorite ballerina and what current performance the ballerina has? I found that scene confusing.

Unlike most people, I actually did not think all too much about the music. If anything, the music has to be the least memorable part of the whole drama. Usually, I would research the OST or who sang what song during a scene, but that did not happen at all with this drama until the end scene where the two co-leads were walking in a grassy field.
