It's actually pretty common to be asked those type of questions pretty much anywhere when you hit a certain age. Plus, romance and love lives are usually a pretty fun and exciting topic of conversation among friends. However, if you and your friends don't really involve yourself in love and dating then it probably won't come up.

is it just a korea thing where everyone is so hopelessly obsessed with each others dating lives and relationship status'? Is it just a trope in all of these stories with romance elements between the main character and their friends or acquaintances or is this like a real reflection of the social culture over there. Or maybe it's like this everywhere and I've just never met anyone who barrage the people around them with endless questions about who they're with and when they're gonna get serious.
