especially for girlgroup .
atleast for 3rd gen we have some nonbig3 gg that are actually on the top like Gfriend and Mamamoo. Group like Momoland,Lovely,OMG and WJSN(As Your Wish our new year anthem) also have some big hits. So eventho BP,TWICE and RV dominating but non big3 gg still thriving.
But i dont see it happen on 4th gen. In fact, maybe GIDLE will be the only non big3 gg that make it. (IZONE is disbanding next month so i purposely left them out). With the current group charting situation, even group from big3 isnt doing as good as their senior. Everglow and Loona both are great on their own way but they are huge (or atleast relevent) everywhere except South Korea.
But again, we never know. Maybe there will be another Momoland and EXID situation ?
