We all know the primary reason we are all over Descendants of the Sun is Captain “Big Boss” Yoo Si Jin (Song Joong Ki). He’s become one of my favorite male protagonists in a K-drama, so central to the story that he takes attention away from the female lead. At the same time, he reinforces male friendships.
Don’t get me wrong, I see you, “Big Boss” Yoo Shi Jin (Song Joong Ki) right there, but his sidekick Chief Master Sergeant Seo Dae Young (Jin Goo) is no slouch in Descendants of the Sun! Even though those brooding good looks may suggest that he’s an aloof loner, he’s actually great friends with Shi Jin. They seem to be good colleagues: going on special ops missions, hanging out with their respective stuffed animal dates at the coffee shop (for the record, I think Dae Young’s is cuter!), saving the youth from a life of crime. But it’s Dae Young’s constant deadpan expression that cracks me up (and Shi Jin always goes along with it!). He is also a loyal friend, always having Shi Jin’s back.
