an old saying has it "there aren't ugly idols" but there's also one that states "kpop has never been all about the music" so what do you think?
imo, i do think a big part of their hype is due to their insane visuals. heck, even i got interested in them and watched all of their content because of minji and haerin even though i didn't find their music as good as the hype prepared me to be (don't get me wrong, they're bops just not exceptional bops).
