I'm looking for the type of feeling I get when watching certain characters and their dramas -- story-lines, attitudes or romantic couplings that make you want to emulate them and/or just be a better person?
Some vague examples:
The Reply Series ('88 most of all)
Dong Yi (self explanatory)
Love Rain (oddly, Yoona's character really did it for me in that one?)
The Moon That Embraces The Sun (Kim Yoo Jung's Yeon Woo, specifically)
Delightful Girl Chun Hyang (in this one, it's the couple that radiated that feeling -- especially him literally becoming a better human because of her -- rather than them individually)
Essentially, just any characters (or their stories) that have beautiful hearts or selfless dispositions.
