She often say that she like strong concept more
and she said in an interview that she doesn't want to be an idol who do cute stuff or full of aegyo and would prefer be an idol who wielden the image of idols
also her rap skills are not highlighted in Twice songs
meanwhile Itzy songs would be more fitting for some rap parts
even on stage the way they are style , i think chaeyoung would be much more better with the makeup and style of itzy members than she does in twice. Her popularity would be crazy in Itzy i thin
