Ooooh, yummy! This is a pairing I don't usually read, but the setting intrigued me. I love fics that take the characters out of the UK, and this was really well done. (I've never been to Korea, though I've been to other Asian countries and so it all felt very authentic to me.)
I really liked the slow reveal here, the fact that even at the end Ron was uncomfortable with what was happening between them, but kept going because he didn't know what else to do. Both of them seemed like very real extensions of who they are in canon. Great fic!
