A couple of years ago cute concepts was the thing ifans hated the most. Being described as cute was considered an insult. When RV came back with Rookie their fans stretched all sorts of semantics to avoid calling the concept with the C-word.
Now present times ifans are suddenly embracing cute groups like Weeekly, STAYC, and to a lesser extent Wooah and LIGHTSUM. Nugu girl crush groups get mostly ignored.
Their change of attitude seems to have happened when Twice switched over to more mature concepts.
