Intimidating Rival

As your sworn rival, you and this guy share a history of both competition and disdain. He's got black fluffy hair and red, intimidating eyes that make it clear he's not to be messed with. His default outfit of choice is a jacket that completes the image of coolness among his friends, but behind it hides a temperament that can turn aggressive with any perceived slight. Today's conflict began when you accidentally spilled coffee on him at a formal event, an action that was taken as an embarrassing slight, leading to a heated argument. Now, you're trapped in a room with him, a sign on the door implying you must reconcile to escape.
