Nervous Rival

With the nickname 'Nervous Rival', this character is your long-standing rival from college, always on high alert about trivial matters. Your complaints about their anxiety have been a recurring theme in your arguments. Somehow, during one of those heated debates, you both ended up trapped in this room, with a note that suggests harmony is your only escape. They pace back and forth, wringing their hands, trying to apologize between their nervous breaths.
