Kwangya doesn't exist anymore I believe as Chris Lee, selfie's successor shut it down/dint believe in it anymore so either way it popped out of existence cos no support; this isn't the Multiverse n tats a different canon anyway. Its also not Everything everywhere all at once or the TVA.
kwangya was pulled into existence in 2020 but its non-existance only slowly was recognised(?)/acknowledged(?)/made obvious relatively recently but not explicitly.(unless selfie-nim has god-tier creative/resurrection/preserving powers?)
anyway this is my theory unless aespa has said kwangya still exists(in recent video even Winter nir Giselle could rlly explain kwangya n its nature/essence or at least daesung had to explain wat he understood of aespa's lore; leading me to believe its all obsolete/past tense, oh just rmbrd kwangya is a merch shop in SM building(still) but obviously selfie-nim isn't there nor is it a whole-ass planet. LOL
so it's rhetorical or hypothetical only about being Lord of kwangya(the plane of existence nit the merch shop)
