This has happened before... You can't tell if you should be creeped out, but once again you open your locker to find a piece of paper stained deep red; blood. It's still disturbingly fresh this time, the metallic smell wafting up to your senses as you examine it, noting a small heart at the fringe of it.
You don't know whose blood this is, and the more this repeats the more you question wether you actually want to know. The feeling that you're being watched comes over you again as your mind wanders, focusing on the vibrant stain.
You stash it at the back of the locker, too stubborn to throw these away, closing the door before turning around to rest your back on it with a quiet sigh, rubbing your eyes.
Just as you were coming to your senses, a girl bumps into you, falling to the ground as her books do the same. This felt intentional.
