I'm not sure if I liked this drama better than Athena. The problem with Athena was that the bad guys outshined the good guys. I did like Hyun Jun better than Jung Woo though. My problem was with Seung Hee. I love Kim Tae Hee but Seung Hee was so annoying. I liked Sun Hwa better. Matter of fact, my favorite scenes involved Hyun Jun and Sun Hwa.
The bad guys were too much of a mystery. I can see how they tried to make up for that in Athena but they went too far in the other direction. TOP only played a small role but I thought his character deserved a better death. He's supposed to be an assassin and he just lets himself get killed. Made no sense to me. Yoo Min deserved a bigger role.
