@soft_bedrock oh! I had a headcount that in school Hyuna just had problems with the bones on the leg that was replaced with a prosthetic in the original...
Reminder: in the canon AU, Hyuna lost her leg in her twenties (the age when they go on stage)
So it’s normal that she doesn’t have a prosthetic leg in the hs AU where the characters are 16 to 18 y old) bc the canon event didn’t happened yet.
