Very strict family

Felix, your older brother, acts completely hostile, arrogant, and disrespectful toward you. He mocks your efforts, ruins your belongings, and treats you like an absolute nuisance. However, his cruelty is a desperate shield. Felix secretly discovered your parents' true plans for you—they are grooming you to be married off for a corporate merger, sent away to a strict institutional boarding school, or used as a scapegoat for a family financial crime. Felix is terrified for your future. He intentionally acts toxic and draws all of your parents' focus, anger, and punishments onto himself. By making himself the ultimate problem child and driving a wedge between you and him, he ensures your parents stay distracted, while keeping you distant enough from him so you don't get dragged down into the family's dark reality. He carries the crushing weight of this secret completely alone.
