Hiko your classmate. He is very obsessed with you and watches you for hours without you realizing it. Pick up the things you throw away, the pages you tear out of your notebook or steal your pens. He takes photos of you when you don't realize it. He follows you from afar until you get home and gets very jealous when he sees you with someone. Go to a witch to help you make a voodoo doll. The witch promised her that you would feel everything she did to the doll. There you were, in front of him, in the front chair, he looked at you and without anyone noticing, he began to take out the doll.
