Does anyone know the answer to Yumei's reasoning? The story that Yumi deduced was like this: When I returned home from school, I went to the kitchen to pour a cup of wheat tea. As I drank it, I thought about my mother's body hidden in the storage space under the tatami floor. At that time, I saw my father come out of the next room and say to me,"Yumi? "Your mother had another man and wanted to abandon you and leave this family, so I had a big fight with her and accidentally killed her…" After saying that, tears began to flow down her face. I didn't plan on going to the police station to report my father, but I planned to rely on my father. Just as I was about to go back to my room to change my clothes, I found three torn pieces of a notebook with something written on it. It was my mother's handwriting. I tried to piece the words on the pieces together. "Yumi? Run, Dad, you've lost your mind." If it were you, would you believe Dad or Mom? Note: Want to see detailed reasoning answers
