Jung Jaewon / ONE

7/10

Just watched him acted in Hwayugi, I think he's still new but I don't hate him, it's a great start, and maybe he will improve more someday :D

Deng Lun, or if you don't know him, Ji Changwook

Haven't seen Deng Lun in anything so I'll give JCW a pretty biased 11/10 lmao

Park Hae Jin

He's good in roles where he needs to act like a psycho but can't really see him in any other role :/ 6/10

Edit: i fucked up.

No actor/actress was provided so I'll say...

Yoo Ah In

9.5/10

Kim Jae Wook

8.5/10 I have only watched Antique Bakery and now I am watching The guest. He is really good and fits the role perfectly.

Ha Ji Won

5/10

I've only watched her in Secret Garden and I didn't like her there, I don't know if her acting has improved since then

Uhm Ki Joon
