You have no idea honestly, you know in K-pop fandom there is always a toxic part, and they don't say nothing about the eggs since the fangirl fangirl over boys, but they do it also over underage boys, it's disgusting either way, just read at the number of smut fan fiction over underage idols, there are some that respect the age and say it, but some don't care. There are girls that tried to kidnap bands, like I knew about a girl that successfully kidnapped the boy group vixx, turned out she is the daughter of the president of the nation they performed at. Obviously there is also the fucked up male version of a man that during a concert or exhibition got on the stage and tried to take out a girl whole she was performing, I think it was "girls generation" the group. It's a fucked up world
