Who are the most popular 4th gen female idols in Korea?

Ryujin

wonyoung and then soyeon

Jang Wonyoung Cause she is queen and many jealous netizen hate her for nothing

Yes she is the most intelligent and loyal idol than I Stan

Ryujin is popular in west but no impact in korea so yeji and yuna can beat her in all the categories

Wonyoung as everyone already stated and probably Soyeon.
