I watched this drama to see what the inmense chemistry Hye kyo and Joong ki had, but when I started watching I didn't even feel it. To this day, I don't know why they started dating on the show. The story seemed to start well, but when they reached the base it seemed like the story had halted, and it had to do more with their "chemistry". The second lead couple, had a better structured story and had chemistry to share with the Hye kyo and Joong ki. The final episodes are pretty interesting, but it doesn't really make up for the lack of story during the rest of the 6 or 7 episodes from before. Final comment, the OSTs' were also pretty good to make up the lack of plot.
