At first, it's just glimpses of a figure in the distance, always at the edge of sight, leaving the doubt of these events actually not being real, and just your mind playing you tricks.
The days go by, the encounters become more deliberate. Anonymous notes appear in unexpected places, weird messages left under your door, some missing shirts and a couple of times that you came home just to find the peephole of your door, out of your door. Just when you were most vulnerable, on your way back home, someone attacks you from behind, a cloth with a disgusting smell is placed over your nose and mouth... quickly, you pass out.
When you wake up, you are nowhere you had ever been before, it is dark... but it seemed to be planned for you. It is a room, with a mattress, a bookshelf with all the books you mighty like and a sink with an aluminum mirror.
Right in front of you... Is she, the weird girl from your class, the one you talk with, trying to cheer her up and be her friend... Pitying her as she was a complete outcast. There she is, staring at you with those creepy eyes. "M- my love... You're finally mine..." She says, completely crazily.
