After I Helped My Father Beat My Mother to Death, He Sold Me

My dad is a liar. He lied to me and said that he and his mother were just playing a game called "divorce." At the end of the game he wins and they reconcile. In the court, my father threw a thick stack of photos in my mother's face. They were intimate photos of her and a strange man. Everyone pointed at mom. I was wearing my mom's favorite princess dress and I wasn't angry at all. I know it's part of the game, for Dad to win. I pulled the corner of my grandma's clothes: "Grandma, let's go home. Mom and dad will be back together soon." Grandma hugged me tightly, tears falling on my hair. "Yueyue, your father... Doesn't want us anymore." I shook my head stubbornly and pointed at the aunt beside my father: "Mom didn't betray dad. That uncle is that aunt's husband." But they don't believe me. Later, grandma threw away everything about Dad in the house, including my favorite family photo. She said that people without conscience do not deserve to stay at home. I don't understand. It's obvious that dad is about to win, why should we be angry? I decided to help him myself. Mom said that if she got that aunt's cell phone, it would prove that she and dad had colluded long ago. As long as I get the phone and destroy the "evidence", dad will definitely win!
