It's surprising to me, most 3rd gen idols who are acting are known more for their group image, rather than the breakouts of idols like Hello Venus Nara.
Why? Most of 3rd gen has disbanded. Only Blackpink, Twice, Red Velvet, Mamamoo, Laboum, Oh My Girl, WJSN, Dreamcatcher, Weki Meki, Momoland are left. Out of those Laboum, Weki Meki, Momoland aren't really growing, Oh My Girl and WJSN are pretty stagnant for now. I feel like we should have seen more breakout stars than Bona, Sejeong, Mina...but there's less.
EDIT: Oh crap did Elris redebut? Them too then. CLC & Dia are p much done tbh.
Surprisingly Sexy GGs are still alive like Hey Girls, ChicAngel and Laysha but they aren't going to be acting. Brave Girls? can be on this list too since all redebuted in 3rd gen. Favorite has disbanded.
