I would love to see one like that in korean dramas. New kind of feeling if you can watch that one. I watch some of that in movies but its in Philippines. Of course the main lead girl is pure korean and its Sandara Park. She star in several movies in just a span of two years and one movie was she portrayed think a half fil half korean who came to the Philippines because she was forced to stay with her filipina mom and live there with her and she don't like it at first but then later on she adjusted very well or something like that. She was paired with her with her real boyfriend that time (now ex). But I am not sure if that is applicable in Korea. Few half korean half other races barely have lead roles and its always supporting role or other wise just cameo roles. In my country, almost all actors there has mix of races. Fil-am, fil-brit,fil-german, fil-japanese, fil-chinese, fil-spanish, fil-italian. You name it. And even other actors that doesn't have filipino blood sometimes lead in a drama or a movie like sandara park and ryan bang and one brazilian-japanese model and actor who won big brother filipino version. So basically it's really up to the korean society if they are willing to see this kind of stuff so that their entertainment industry will grow in terms of beind interconnected with other races. I am not familiar with Japan because I rarely watch their dramas.
