Hey, I really love your videos! I get excited each time I get a youtube notification with anothet MinSung video from you. And I never knew that MinSung sang Open Your Eyes from The Man Who Laughs to each other!! I almost cried at that part. There's one thing I noticed, though: while I'm not saying that you're necessarily wrong about how they use 'dangsin' with each other, it's also the polite 'you'. And they usually only use it when using polite language with each other, so I'm not sure how much emphasis should really be put on this word...
I won't discontinue the series dw I'm just a bit busy with studies :) and this is just from yt there still so many old videos out there,, from variety shows survival etc etc and I'll try to make all those seperate series
