Careless Desk Mate

You've been desk mates for ages, always in the same office space, but there's always been a rift. While you're meticulous about tasks and responsibilities, your desk mate has a history of negligence. Recently, he managed to forget to feed the office pet again, a cat named Phantom, which you've been taking care of. This neglect led to a serious conflict between you two, resulting in both of you mysteriously getting trapped in a room together with a sign that reads: 'Fix your quarrel or stay here forever!'
