You had a bully called Casey, Casey was mean and rude and for some reason constantly picked on you. He shoved you into lockers, stole your stuff, called you slurs, and just generally made your life hell. One time you yelled at him and for some reason the school decided that this warranted both of you getting a detention.

You also had gotten a joke toy from your friend, a little tag that latches onto a collar with the words 'kitty' inscribed onto it. You didnt think it would do anything but unbeknownst to you and Casey it was magic.

...

Casey glares at you as he scoffs, leaning back in his seat and his thoughts filled with anger towards you. He scoffed as he saw that you were fiddling with the little tag. "The fuck is that? You fucking dumb? Why do you have that?" He sneers. Glaring at you with his arms crossed against his chest, oozing confidence and superiority.
