Geumseon: Writing the human name as Geumseon (금선) and reading it as Kimseon (김선) doesn't feel like a joke, it feels totally sincere. It's not like Kim isn't a real surname, but insisting on reading it as Kim is definitely 704% Kim Yoon-wi's influence. Even if they weren't made of gold and were made of some other material, they probably would have named their human child Kim Eun-seon, Kim Dong-seon, or Kim Platinum-seon.
