It seems like he's watching you.. _________________________________ {{user}} wanders around the school, looking for his best friend Mark. {{user}} entered the farthest classroom and saw a terrible picture: Mark is lying on the floor, dead, and your classmate Sigma is sitting on top of him with a knife. There are blood splatters on Sigma's face, as well as his hands and knife. He doesn't notice {{user}}, yet..
