I promise all of your idols from those weird nugu companies like Hybe and Starship have auditioned for a big 3 company and got rejected because they weren’t talented or pretty enough.
If you get into a big 3 company and you debut, you deserve the success because the trainees are the top of the top when it comes to talent and visuals. Unless your name is Giselle and your aunt is dating the chairman of SM. It’s like getting into an Ivy League, not everyone is good enough.
