I used to meet this kind of people claiming older groups is better than the popular groups now usually Bts and Bp just to look different and acting like kpop is a history lesson. Please, nobody need to know every groups in kpop from the dinosaur era just to be a fan. And if you ask what songs they know from those groups and they only know few songs or even none.
And come those who only stanning nugu groups to look ' I'm different, not like you peasant '.They will make long essays saying that popular groups are talentless and they are popular only because of company, looks and whatsoever , not because talent. And make an essay of 10 pages that say other people have no taste just because they are stanning a popular group. But they will also be the first to come out of fandom when the group they like becomes famous.
