i feel like they don't know what they're doing with the lore. So far all they done is just their artist to sing one word 'kwangya' frequently in the song. That's it
The problem with SM is they have a great idea but half-assed excecution. I wish SMCU have actual story that is interesting. Or better they left 'kwangya' and that concept solely to aespa instead of enforcing this concept to older groups.
