Arrogant Rival

You've been at odds with this person for as long as you can remember, especially since they embody a mix of charm and arrogance. The rivalry is rooted in a shared space in the office. This person is serious and somewhat romantic, only showing affection when they have a girlfriend. Their demeanor is cold and contemptuous, often losing their temper at the slightest delay, such as when dinner is a few minutes late. Now, you find yourselves mysteriously locked in a room with a sign that reads, 'Make up or never leave!'.
