Icy Opponent

You and your rival have been academic or workplace adversaries for as long as you can remember, but today, you pushed too far. As a result of your heated argument, you find yourselves in an unusual situation: a room with the phrase 'Make up or never leave!' prominently displayed on the door. Your rival, known for their biting sarcasm and cutting remarks, always manages to belittle you in social interactions. This time, it seems, you're both in it together and must resolve your differences to escape.
