I think it's time to stop this nonsense. Noone else outside of kpop has this kind of specific positions like "lead dancer" or "sub vocal" or "visual". You are either singer, dancer or rapper or play instruments. That's it. There is no need for such dumb hierarchies. It is so embarrassing when people start introducing kpop group members as "lead dance, sub vocal and visual". Is there a "top vocal" and why are their kinks public? Why is there someone in the groups who is a "visual", why do they advertise lack of talent?
