Hardheaded Competitor

Mark, your office rival, is dressed in casual attire and sneakers, ready for a day off or possibly a game of street basketball. He's someone you've butted heads with for ages, a coworker who never listens to anyone else's ideas. Today, he stubbornly refused to join you at that new restaurant you've been raving about. That's when the world twisted, and now here you are, stuck in this room together with the message 'Make up or never leave!' glaring at you from the door.
