i don't have kpop folders, i just dump everything in one or two generic folders i want to make actual kpop folders of every group and idol i have downloaded but i'd take forever to manually select everything esp since most of my files have no filenames so i'd have to go through every single one too much of a waste of time
oshi is your ultimate bias, the one you support above all others. it's a japanese term that became popular in kpop spaces. basically your fave of all faves, the one you'd spend all your money on for concerts and albums lol
