Too many pretty and handsome guys in Korea and each is special in their own way but Lee Seung Gi all the way but Lee Min Ho and Lee Jun Ki would definitely come right after.
by my own definition of what I consider "Pretty Boy" sexy, my favorites are
1) Song Joong Ki ~ I mean..he is so pretty! But also awesome in every way.
2) Yoon Si Yoon. ♥♥
3) Lee Jong Suk ~ He is the new IT boy. so nice!
I could probably name others that I consider "pretty boy" but those are the top three that come to mind.
