It is probably because of her recent controversy
Which is getting extremely big
Koreans are even asking for her to leave Korea
Yeah and I call bullshit on her testimony to the police about everyone not knowing the guy that hit the fan. Bruh this is the entertainment industry and you are celebrity NOBODY is hanging around you personally unless you know them or your friends know them personally. She saw things turning ugly because of you watch the CCTV she clearly gets up and tries to grab the guys arm before he even got close to the teen, so that tells you she knows something about the guy. Because if you just saw a "total stranger" you wouldn't rush to try in restrain them when the situation is not violent or confrontational . They must not be a Stranger because obviously you know something about their behavior and emotions to instinctively go to stop them. People don't do this with people they don't know because THEY DON'T KNOW THEM to know how they would react.
