i think of it this way, i sort groups/soloists into one of these catagories:
ult - god mode (hyuna, shinee, and nct)
stan - know all the members, fully commited, love them, love their music (ex: clc, (g)i-dle, itzy, 2ne1, sunmi, chungha, bigbang, exo, vixx, and ace)
casual fan - starting to like them, have been keeping up with combacks, and slowly learning the members or like but never got fully invested (ex: x1, ab6ix, girls generation, wjsn, got7, and aoa)
neutral - they're meh, only like one song, or only find one member interesting (ex: nature, 1team, iz*one, up10tion, f(x) and hotshot)
dislike - for the most part no groups are here but sometimes particular idols fall here (not going to give examples for my own safety lmao)
