I- fans never cared for IU, OMG, Brave Girls, Mamamoo and aespa until they showed signs of becoming big in the industry.
Koreans never cared for BTS, EXID, Loona, Lisa, etc until they hit some sort of international/domestic milestone.
My vote goes to I-fans as BTS is the only true example of international impact that translated domestically later.
What about you?
