That would be Lee Jae Ha from King2Heart
and nobody in particular from Rooftop Prince :p
More or less Seo Jun from Love Rain...
In Return of Iljimae it would have to be Iljimae hahaha (Jung Il Woo) He's worth the watch!
Sahara Shinji (Taiyou ni Kisetsu)...guy was pretty pitiful tho :(
Seo Joon (Love Rain <3)
Hee Jin and Boong Do from Queen InHyun - they are just amazing together! Jeremy - You're Beautiful...LOVE HIM! Prefered him than Tae Kyung
Shut Up Flower Boy Band Joo Byung Hee - even though it's just a cameo:-)
Ji Soo (The Secret Angel)
Suou - Vampire Host - <3 Such a cutie, Reminds me of Yamamoto Yusuke :D
Que Sera Sera. The lead guy, I can't remember his name though (horrible with names). His character was cocky and blunt. He was sort of a jerk, but at least he said what was what.
Long Love Letter -> Asami. <3 But I really liked Takamatsu and Ootomo, too. Especially together. :)
My fav out of Hana Kimi was also Nakatsu Shuichi, like you guys but the last drama i watched was Kpop the ultimate audition, so i think my favorite was probably kang chang min, because i loved his voice
Joseon Power Rangers from Rooftop Prince
