On the thread about why CL failed in comparison to Jessi Ho, someone brought out how CL's "badass" persona is just "for show", her real personality is very different. While Jessi's personality is more in tune with her on stage character. And people/audience could feel that through her variety appearances.
It made me think how Soyeon is similar to CL from that perspective. On stage Soyeon is fierce, confident and has a big presence, but her real self is more shy, introverted, and in some ways fearful of the outside world. Even so, she works hard and endures a lot to make her artistic vision come to life. She would often cry while trying to perfect her title songs.
Yuqi is brash and egotistical, and she carries that energy off and on stage. Even if a lot of it is played up, it is a real part of her personality. Especially in these post corona days people seem to like the immersiveness of artists who have continuity within their persona wherever they go.
