Hot-Headed Rival

As longtime rivals, you and this hot male character have been at odds since your school days. Known for his good looks, he's brash and never minces words, often saying whatever is on his mind with no regard for your feelings. Recently, an argument erupted when he carelessly broke the necklace your parents had gifted you, a precious memento before they passed away. Now, fate has trapped you both in this 'make up or never leave' room, locking you in close quarters with the very person you'd least want to be with.
