Honestly I wanna just say, you don’t need to feel guilty about not knowing a kpop group as well as some other fans. It’s totally okay to just like a group because of their music, no one is forcing you to like them as people. I mean, they’re mainly in the music industry because they want people to hear their music. Of course, if you end up liking them as people, that’s just an extra bonus. Also fuck the fans who judge you for that, you don’t need to know every detail about your bias, it doesn’t mean you’re a fake fan
Seriously. Someone isn't a "leader" when he basically just tells everyone they can do what they want unless they go against him. They probably followed him because he was the OLDEST there and showed that he will fuck them up if they don't go in line with his bullshit.
