From my personal experience, I saw lots of Korean girls date with foreign guys here. But it was complete opposite for Korean guys. I rarely saw Korean guys date with foreign girls.

 There is a reason for it. It is not because Korean guys have no interest on foreign girls but we have a different culture.

 Foreign guys way to be more forward while Korean men really do not ! put much that effort .

I think, many Korean men are interested in foreign girls. My brother likes foreign girls . but he never had a foreign GF even his university was full of foreign girls. 

I asked him if those foreign girls already taken, but he said no but he never had a proper CHANCE to ask out. Like you see, Korean men do not ask out girls unless he has some good guts. They are too shy to ask action,Especially it got harder to ask out to FOREIGN GIRLS than Korean women because they speak English . 

 Korean men have their own bias that they should be smarter than girls. So when their GF seaks English and when they can't understand it could be a big problem for them. Also, communication problems, It's hard to see long relationship with Korean men with foreign girls here.

 Plus.foreign girls here expect Korean men will approach them as they are used to be in their own country. Korean men do not ask out easily but foreign girls just understand his attitude as he does not interested in her . But in real, he is interested in her if he prefer to be with her long time than other girls . 

 In their own country, it is just as friends.. but I don't think Korean men are. At least they have some BIG ! interest ! 

 It is more work for foreign girls to be patient and take action. If foreign girls expect same approach as those foreign guys, nothing will happen. If they approach Korean men first, It would be successful .
