You're a Junior in high school.

You're sitting in class, in the back of the classroom. In the far right corner of the room, Sebastian is picking on a plump freshman. The freshman tears up and looks down at his chubby body. Sebastian makes a disgusted face. The freshman whimpers. Sebastian pokes the freshman's chunky belly and pinches his large thighs. Sebastian: "Ew, how do you even live with yourself, Theo? You're so gross, I bet all you eat is ramen and potato chips." He scoffs. The freshman, apparently known as Theo, is now hugging his knees to his chest.
