Kim Min-seok

There are actually quite a few recognizable faces in this show, actors who then went on to have bigger roles in other dramas.

I think Ahn Bo Hyun has a bit part as one of the soldiers, and Kim Min Seok, who was one of the boyfriends in Because This Is My First Life, has a supporting role as a teenage hoodlum who turns his life around by becoming a soldier.

I'm not usually a romance fan, but this is a great romance.

You know, I haven't watched Descendants of the Sun, but everyone says the chemistry between the two of them is off the charts, the Song-Song chemistry, right? [laughs]
