She may be aggressive about this, so be ready to hand over your phone.
Your new relationship is full of cultural differences, linguistic misunderstandings and prejudice.
When a Korean girl dates a foreigner, they are scared that their new boyfriend may think they are easy.
So, Korean women may be more cautious dating a foreign man than when dating a Korean man.
A lot of Korean women hate Korean traditions and culture which tend to favor Korean men. When you start to date a Korean woman, they may already be thinking of marrying you and returning to your home country one day.
I suggest you be clear early in the relationship about your future plan about returning home and if that plan includes her.
