So I'm assuming you guys have seen the tumblr post on Kim Yeo Shin, the "Idol Killer." If not, go look up what she's done. She's a sasaeng for multiple groups, and people are saying that she's the one who poisoned Yunho in 2006, and poisoned Himchan in 2012. I figured since I don't know if the tumblr post is 100% real, I did some research. It seemed to be the first article on her at first, but then I saw an article from a year ago talking about the Himchan incident. Apparently no one knows who she actually is yet, but she announced that her next target is Sehun.
