People like to watch girl group being chaotic and loud that's why ive can't gain much fan outside of their music.
I watched IVE 1,2,3 season 1 and 2, and their bts and they are not chaotic and not entertaining.

They have great music so far, but if they can't keep up with great and fun variety show and vlive, their fandom won't grow.
Music can make people a casual fan of a group, but variety show is the content that make people falling for the group.
