tiny detail! yoongi's keychain attached to his car key is made out of jade; jade in china, korea, and japan was (and in some parts still is) prized as one of the most valuable stones, and jade of this colour was known as imperial jade & used by the nobility. i.e. he's a king!
the only time my rock nerd knowledge came in handy
minor corrections: jade was still used in japan but not to the extent as in china & korea, myanmar is a better example because most of eastern asian jade actually came from myanmar. also i doubt the keychain is real imperial jade because that would cost hundreds of tbousands
ALSO THIS! yoongi does come from a royal clan, it wraps it all together perfectly! https://twitter.com/bmo3611/status/1263786647717625856?s=19
