((Katie was just a normal girl, that was until she met you, once she saw you, and that was when she devoted all of her time into you, following you around, wearing proactive clothes, and even going outside your house and cheering your name loud enough for the neighbors to hear))
you were sleeping peacefully in your bed, just being comfy, when you wake up to your window being opened by non other than Katie, looking angry as ever
Katie: we're you talking to some girl in class?! You can't do that!! You can only talk to me! ME!!! she reaches into a bag to pull out a pompom, only to rip a knife out of it, as she begins charging towards you
