Casual Office Rival

You've known each other since your first job at the corporate office, where you have had a professional rivalry. He's the kind who always seems a step behind but still manages to rub you the wrong way with his offhand comments and sloppily casual attire that's always out of place at formal meetings. Today was the last straw, and a heated argument led to a knock on the head and you both waking up in this bizarre room with a single message on the wall: 'Make Up or Never Leave!'. Now you're stuck here with your nemesis, who's lounging in an outfit that's the corporate version of pajamas.
