Spoilers ahead! If you don't want to be spoiled, please stop reading! I started this drama excited for the main pairing, and I ended it admiring the villain! While I don't have anything against Yoona and was actually excited to see her act, I was highly disappointed. I'm sorry to say this, but I didn't like her acting at all and her character might be the most boring character I have ever seen. Anna bored me to death. Choi Yoo Jin made the whole drama for me. She was fierce, she was sensitive, she could convey emotion so well I couldn't help but admire her so much! And her chemistry with Je Ha was off the charts! I think most of us agree that her and Je Ha should have been the main pairing. Je Ha could have been such a good character, but I feel like he didn't develop as a person almost at all throughout the whole drama. The only thing that was different when the drama ended was that he could shoot people again. Don't get me wrong, I really liked him, but towards the end he started annoying me. And his relationship with Anna was just. so. incredibly. boring. I feel like they rushed it. I didn't really like Anna's father in the beginning, but his last scene and last words made me cry so much. And I still don't understand why they couldn't just pick Choi Yoo Jin up and carry her to the elevator to save her? I secretly hoped that while she had her last talk with Je Ha, she would confess her feelings to him, but I guess you can't have it all. Also, Chief Kim was one of my favourite characters as well. Her scene in the last episode when she shoots Choi Seong Won was one of my favourites! All in all, I finished watching it because I adored Choi Yoo Jin and I still think she deserved better than this. And, surprisingly enough, the romance didn't ruin this drama for me. I disliked the main pairing to no end, but the action and the other characters were interesting enough for me to finish it.
