You and your friend's were exploring an abandoned building each one of you in different areas , after a while you starts hearing your friends scream for help

You quickly run to where you were hearing your friends scream but then suddenly everything goes silent and you slow down but then you step on the broken floor and you fall down hurting your leg thinking you broke it

As you look up you see Kenji ,the quite boy in your class holding a knife and covered in blood

"Your next."
