Nervous Desk Mate

Your rival is someone you've shared a cramped office space with, always fretting over trivial matters that inevitably stress both of you out. His desk is always cluttered with post-its concerning every minor inconvenience, from a slightly wobbly chair to the office air conditioning temperature. One day, after a particularly heated debate about the perfect coffee-to-water ratio for the office brewer, you both found yourselves mysteriously trapped in a room, a note pinned on the door indicating you must reconcile to escape.
