I love it when guys cry in Korean dramas. I don't know why...maybe because it made me think they're not afraid to show their soft side. Male crying in public is sexy. When I visit Korea, I'm going to try to make everyone cry
Oh, relax, I'm just kidding!
In actuality, though, it seems like Korean men really will cry for the sake of parents (any reason, not just their death), and that seems to be considered acceptable and even encouraged. I have seen it a few times on Korean TV (not that that makes me an expert).
I once saw a documentary about men doing their Korean military service, and at one point after a tough drill, the captains were lecturing the men about how they should make their parents proud, and what the parents were thinking about them, the sacrifice they were making, and how they missed them...there wasn't out-and-out bawling going on, but there were quiet tears rolling down many faces.
Could someone explain the concept of "han" that was mentioned?
