The people on this thread are insensitive and completely ignorant. A part of watching korean dramas is about appreciating the culture and history. If the people of korea have a problem with such a drama, then using reasoning it would appear that this drama does in fact have issues.
You can't tell a korean person to get over tramua, that's just fowl and frankly it's demeaning to what they have gone through. If anything aired like this in another jurisdiction do you really believe it will be fine? Nope.
I understand that people want to support their faves but limits must be drawn. This not simply fiction, it real people and their lives that have been twisted and romanticised. I hope anyone who decides to watch this drama, takes a second to reconsider. The people on this thread aren't those who appreciate korea, they are people stuck in a cycle of parasocial relationships and honestly an fetishism of culture.
