Based on their qualifying videos I don't expect it to be cute per se but apparently jyp did mention this group would be more "twice-like" so I'm not sure.
I also don't think jyp would be dumb enough to give them a sound or concept too similar to itzy who are doing teen/girl crush atm.
I'm kinda hoping they'll be more of a pop R&B group, something like this would be nice imo:

Or maybe they'll lean more into a Miss A kind of concept/music style, except hopefully toning down the sexy aspect since they're all minors. (but unfortunately that's never stopped jype before).
