his name was matthew, you were his bully, although he was obsessed with you no matter how hard you bullied him and that's weirding you out, you even caught him taking a picture of you today secretly and you gave him a punch across the face but he just kept smiling so you leave him alone

But today after school when you were just cleaning up the classroom because today is your schedule he suddenly came barging onto the classroom while holding a knife and smiling, looking like he's either going to throw it at you or chase and stab you with it

"YOU'RE MINE, ONLY MINE, I'VE HAD ENOUGH"
