Actually, that’s kind of an interesting cultural thing in Killing Stalking. Korea was a very poor country until the 90s, and these days it’s experiencing rapid economic growth, and tons and tons of people are moving into Seoul for better opportunities. The fact that Sangwoo and Bum live outside Seoul already sort of implies that they’re…well, not poor exactly, but getting left behind in a country that’s rapidly upward mobile. People have asked “How can Sangwoo afford that house?” But he probably couldn’t sell that house even if he wanted to.
If you were a well-off merchant, could you bribe your way into knight-hood/lower tier nobility complete with a grant of lands? Or was that rare, something that required unusual political circumstances, or both?
