I don´t really get this type of "Cinderella stories" in kpop in general. actually becoming a trainee IS expensive. people who are from working class families would never even dream of it. if you are middle class you are struggling, so stories like Suga´s who had to decide whether to spend his money on a bus ticket or save it for a tuition are supposed to sound horrific, but have you ever met an unfinanced uni student? most of us have been there.
but I think it is not their sales that make them "the Cinderella stories" but more the fact that they are a group from a relatively small country and they have made it worldwide. sure, there were groups before, they are not the ones to invent kpop, this has been discussed and debunked, BUT they are the ones who have made it into local radios of countries like mine and like many others. that even now know BTS and Blackpink and that is where a general knowledge of an ordinary radio listener goes. I really do admire them for it and in that way, they do deserve their own "fairy tale".
