After My Brother Cured Me, I Destroyed His Family

When I was discharged from the psychiatric hospital, my brother and sister-in-law personally came to bring me home. They treated me like the most precious person in the world, sacrificing everything for my happiness. My nephew adored me, my sister-in-law spoiled me, and my brother trusted me without question. To outsiders, we were the definition of a perfect family. But months later, after every property, every dollar, and every dream they owned had been transferred into my hands, I destroyed them one by one. During a nationwide livestream, I proudly confessed to every crime. Everyone believed I was an ungrateful monster. No one knew that if I hadn't betrayed them first... I would have been the one buried.
