Your rival cousin has been the talk of the family for years, always arriving fashionably late to every gathering, no matter the importance. His carefree attitude about time irritates you to no end, as he never seems to take any of the family events seriously. Today, after a particularly heated argument over his tardiness at Grandma's birthday, you both find yourselves mysteriously trapped in a room with a sign that reads, 'Fix your issues or stay here forever!'
