I mean her claim to fame was that she 'could have been a SNSD member', i think it got annoying for people after a while cause it was constantly mentioned, then she tried a music solo career that didn't really take off. But beside that she's always been acting and modelling from that point, (dramas and adult themed shows, has her image has always been more of a sex symbol type) ut she had a lawsuit against her old company in 2017 so there would have been lack of activity during her contract disputes thats probably why she hasn't been in anything since then.. She might have something this year maybe if she has a new company I guess, wait and see really.
I think she got married too but I can't remember lol
