Well, context definitely matters. We don’t know what you did, how you did it, if she was with her bf, how sane was her bf etc etc. I don’t want to negate your personal experience but I doubt it was just normally casually “talking to a girl” that got you in trouble in a normal situation.

Also 2015 is almost 10 years ago, it’s not really accurate to define it as the current situation.

As for my source, I’m white, my wife is Korean, my ex was Korean, and I hang out alone with female Korean friends a lot. Some very old grandpa may be not very happy about skinship in public, but that’s all. Never to the extent of being attacked or harassed, it’s usually just looking at us a bit with a grumpy face.

This being said, it’s not all perfect. Some families may be less open than others in accepting a marriage with a foreigner (old generations, young people just think it’s cool usually). And not only about white people. The mom of a friend was grumpy about her son marrying a Japanese girl, for example (even if he lives in Japan) But even so, nowdays is rarely open hostility.

Of course idiots are everywhere. So I’m pretty sure there are young guys saying “white guys steal our women!1!!” and getting angry.

Also, an important note is that these days the fight between “feminist” Korean women and men against them is getting bigger. This can influence especially the mind of young men. I was approached by a Korean boy asking me about how women are in my country because all Korean women sucks and are terrible. In that context, I’m sure some guy will use dating a foreigner as an excuse to say how shit and easy Korean girls are.

Anyway, exceptions aside the average population is pretty much fine with it, especially in big cities. It’s not like Korean men don’t like white women too, after all.

Sorry if this is too long, but we’re all here to share knowledge about those countries anyway
