Okay, things. 1. They actually used to be pretty much an aggressive rap group (Except a few songs), go look at their albums before 2015. 2. They lip-sync in music videos, like everyone else. 3. They don't get to choose how they cut their hair. 4.They make all their own music.. have you heard any songs like theirs before? 5. Of course it was planned, it was a music video. And if you've ever loved an idol like the BTS ARMY loves them, you'd understand why we're so attached to them.
