This is a really really very good drama which will show you the true hardships faced by a soldier. It beautifully shows wether there could be a romance between a soldier, Yoo Shi Jin (Song Joong Ki) who can kill anyone to save his motherland and a doctor, Kang Mo Yeon (Song Hye Kyo) who can die to save anyone no matter what caste, religion or nationality.
There are not very much steam kissings and not very less romance.
Therefore, I would say that you should once watch this drama. I hope you'll like it...

•• HAPPY WATCHING!!! ••
