This drama would have been rated much higher, had the ending not been so terrible.. Everything was wrapped up too quickly and badly paced. The drama really dropped the ball with that ending, pissed beyond belief. Even though I know this is mainly an action/revenge drama, the romance literally just stopped progressing around Episode 12. The acting was pretty good from both leads, and I enjoyed all the side characters. OST is definitely one of my favorites. Action scenes were quite well put together however.
