Hello!!! Something I really like about korean dramas and movies is that it's acceptable for male leads to cry which is mostly not the case in American ones. However, I would like to see a male who is not always on top of the game when it comes to scary situations. I feel like the females are often damsels in distress and the man is not afraid of anything. In the few cases the male shows vulnerability, it's mostly for comedy and they're portrayed as cowards. I would like to see a drama or movie where the male lead is under some sort of threat and shows fear, not just I'm-in-pain-but-i'll-make-it-because-i'm-some-sort-of-superman. Any suggestions??

I think Goblin did a good job with the male leads genuinely showing fear and all their emotions. Shopping King Louie as well... although it tended to be more on the comedic side, he's definitely one of the more vulnerable male leads I've seen
+1 Iljimae
Angry Mom (Ji Soo's character, fear for those around him)
Sassy Go Go (again Ji Soo's character)
Two Weeks (not fear for himself, but the ones around him and the ones hes trying to protect)
honestly, I think the majority of Ji Soo and Lee Joon Ki characters have a sense of vulnerability

+ Angry Mom.  Not just Ji Soo but Ji Hyun Woo's character was like that too
