There isn't Illit, BND, TWS also missing.
Illit has just debuted so that makes sense, but that's not the case for the other two.
He always goes to the concerts of his artist during their tours. It will be interesting if he'll go to Newjeans first world tour
So these photos were taken at concerts? I can only recognize bts (duh!) (I miss them!!!) but looking at the outfits it makes sense.
