Kwon Eunbi is going viral on everywhere (and her solo career is also doing okay. not a hit but definitely not on flop category)
Jo Yuri is on Squid Game 2, already a big win for her
Chaeyeon having a semi hit with Knock + multiple variety shows appearance (indicating that she's actually on demand)
Yena is literally own the biggest hits for 4th gen soloist
i have no idea about Japanese member but seems like their existing group are also big there
the only one that we can argue is Minju but shes nowhere near post-IOI & Wanna One & X1 member tier (except for maybe Somi and Sejeong)
wow, its a win for 12/12 of them.. a very rare case where each of member find success on their own, considering IZONE isnt even the biggest girl group during their active year
