I'm honestly out of the loop about what she did but isn't this much detestation a bit excessive?
Well I wouldn't go as far as call her names or that stuff.. other than attention-seeker and other stuff that she is. But basically she's from rich family and got trainee position and close to several male idols with her connections. She dealt them drugs, then when she got caught of using drugs and selling them second time she exposed T.O.P for using marihuana that she had dated. While T.O.P was in court about his case and in severe depression even in point of overdosing on his anxiety meds she made degrading comments of him. Later on she has threatened him to expose more.
This expose and degrading T.O.P made some people parade her as feminist queen which she quickly monetized and started selling sweaters. She made some radical feminist posts which gave bad name to feminism and then she denounced being feminist when people started calling her over her transphobic comments.
Other than T.O.P she exposed B.I which led him to be leaving group and idol life. And she has made comments about several other idols saying they have done stuff like Wonho now. She has also admitted she likes the attention her posts get.
So she's basically rich kid who keeps breaking several laws, but avoiding jail cause her rich parents, while exposing her ex-boyfriend and ex-friends for doing same things she has done to get clout and attention. She has hurt lot of people while parading herself as some kind of hero for exposing these idols. She's currently on social media rejoicing about Wonho leaving the group and exposing more about him cause she doesn't care when someone is already down.
