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?

Answer 1

Wine.

Yumi realized that her clothes were missing, so she began to look around until she saw a glass of ale on the table. She believed that her clothes must have been soaked in ale, so they were placed on the table while she drank the ale. Therefore, the answer that Yumi deduced was that her clothes were soaked in ale and were placed on the table while she drank the ale herself.
