Sasaengs are a real problem, they stalk the idols, and they hurt the idols; all to make the idols remember them. In the past the Cassiopeia Sasaengs were really big and they did really bad things, they almost killed U-Know/Yunho. Now the EXOtics/EXOstans(I don't know what we're called, there's a lot of confusion) or you could call them EXOrcists or just EXO's Sasaengs are getting bigger and crazier. They've crashed a wedding, stalking, injuring, etc.
