I never invested so much time, effort & emotions to any kdrama before the Descendants of the Sun. You always have to wait for the subtitles to come out and sometimes I do even watch the raw episodes just because I can't contain my excitement. Song Joong Ki is such a great actor, he was so great & so appealing with his character Yoo Si Jin/Big Boss/Captain (of the Team Alpha) plus he looks so good in his uniform (more preferrable in everything that he wears) and he's so great at bringing out the personality of the character, the attitude also (I think it's partly because he just got out from the Army). And Song Hye Kyo is just that delicate & fragile girl, so vulnerable that you have to protect but her character Kang Mo Yeon/Dr. Kang, she is more of like an independent woman with a little bit fiercer & feisty if I must say? But there's still this vulnerable vibe around her that you always wanted to protect. And the way she is styled I soooo love it!
