I watch a lot of MV and a lot of KPOP MV. In one great song one of the dancer is wearing a collar with what seems to be a butterfly on it. If you would and wish to check it out, what do you make of the collar? Is it a collar with a bd meaning or a sign of regeneration and change due to the meaning of the butterfly? (Oh, the group members of this glam group are professing Christian, so there are various possible meanings, I suppose!) I love the song; it is fun and catchy! It has the title Pull up by VIVIZ!
