EXO Lay's #ShowItAll show is really hard for his trainees. They're competing with pro groups. Even if they match with #UNIS, a “rookie group”, they won't win. Half of UNIS members are pros already. And Lay's girls do need to improve.
Don't get me wrong, Lay's girls (they don't have a name yet) are talented. Also, the purpose of #ShowItAll is for them to learn and grow. Just that, it's super tough to match with experienced talents.
