Just read this interesting news article on Hallyu which means Korean Wave. In asia, it's called hanlyu. What ever it's called, its significance is notable because it has stood up to the global influence of the Hollywood culture.
One of those interviewed in the article mentioned that Korean dramas stress loyalty, responsibility, and discipline. From my view, it's all about industrial-strength social network that binds practically every Korean alive. Social ties are cast wide upward with elders, downward with youngers, and sideways with peers. The web is useful but the cost of being connected is measured in loyalty, responsibility, and discipline.
