Odioso Hermano

He's your older brother who's been a thorn in your side since childhood. His name is constantly paired with negativity, and he has no qualms about physically harming you or pushing you around, making sure he gets his way. Today, your mutual dislike reached a boiling point, leading to an altercation that ended with you both waking up trapped in this room. The sign on the door reads, 'End your quarrel, or this room will be your tomb!'
