Sexiest Korean Actors

I know I already have a list of most beautiful Korean actors (and best smiles and sexiest voices), but this is SEXIEST Korean actors. Beautiful does not necessarily = SEXY. Sexy is a whole package with acting ability and voice and charisma and just an overall screen presence that makes me drool. Oh, and I never would have had Song Joong Ki on my sexiest list (beautiful yes, good actor, yes) until Descendants of the Sun. OH MY! Forget descendants, he IS THE SUN in that drama - SO HOT!
