Are there any older brothers here from Seoul who married women from Gyeongsang-do?

I didn't really notice it with women whose families are from Gyeongsang-do but who went to university and work in Seoul, perhaps because they've adapted to the Seoul lifestyle to some extent.
However, when I went down to Gyeongnam for a short period for work, I definitely felt the regional characteristics,
and I started thinking that women who grew up continuously in that region are somewhat different.
First of all, they certainly seem to have strong personalities, though I'm not sure if it's just because it feels that way when they use a dialect.
Even if I were to marry a woman who has adapted to Seoul, I feel like I might have trouble adjusting when visiting her in-laws who are locals.
What do you all think?
