The premise was promising and thrilling at first. The fight scenes were outstanding. The story was going incredibly well with the protagonist (Yoon Ji-woo) playing a double agent. The way the story takes a different turn was really predictable. As the episodes went by, it became obvious that Choi Moo-jin might turn out to be her father's actual murderer. I really didn't want that to happen. because it was anticlimactic and his character was portrayed very nicely. He was like a father figure to Ji-woo, which I believe she really needed. I think it would have been nice if there wasn't just one bad side. If both sides had corrupt and good people in them. At the end, I did not understand why they had to kill Jeon Pil-do. I can't understand what significance his death had. I do not believe that his demise was crucial in order for Ji-woo to finally go after Choi Moo-jin. It felt really unnecessary. After finishing this show, I can't stop wondering. After all she has done, what is she left with now?
