Mine :
Gong Yo - well technically Ji Sub was the first Korean actor I know but it was GY who became my most fav, u can say all time fav. Reason why I'm crazy about him still is the boyish charm he exudes despite looking like a man.
Chang Wook - similar reason to GY, but I never really warmed up to Chang Wook in SP like what most will say. I actually fell for him in Healer and I can't believe I watched the show after SP. Tbh I wouldn't have watched Healer but I still chose to watch it. And I must say I don't regret it. Very shallow I must say but his outrageous good looks are the biggest reason why I'm still in trance!
Woo Bin/Jong Suk - it's a tie for me. I can't help it. They are part of the best bromance story I know so it's really hard to choose either of them.
Woobie : I think every time I'm going to write this guy name, I'm going to tear a little or two. I have a strong strong soft spot for him you can say, mainly because he has cancer. I been thru this tragedy with my closed ones so it pains me every time to remind myself that Woo Bin is not okay. Sometimes I feel like I might like this guy the most cos I feel his pain. Many times I have wished to reach out to him and give a tight hug and tell him to continue fighting! I rmb watching UF, had to stop it midway cos of the cancer storyline and I couldn't even take him dying in the show. I was so mad cos it was his first starring role and those cursed writers had to bring in such an angle. If reel itself was too much, imagine how shaken I was when I knew abt his cancer irl? He is an underrated actor(pls watch school 2013), so it's really a loss if he can't do dramas/movies anymore.
Sukkie : I have a lot of dislike for feminine looking actors tbh. But there are always an exception. And that is Sukkie. He is annoyingly adorable and endearingly charming. Every time I see him onscreen I only want to get inside and pull his adorable cheeks. He is so understated seriously! Tbt I can't really hate this guy really! It's more weird to confess that I'm attracted towards despite my ever constant hatred for feminine looking actors.
