My Final Wish

Synopsis

My son was a math prodigy. Badly injured in a car accident, I arrived late to my son's high school graduation party. As usual, he handed me another set of number maze puzzles. He said calmly, "Mom, solve these puzzles and you'll find the key to get in to see me." I called my husband, who snapped impatiently, "Mistakes deserve punishment. Even our son gets that. Why can't you?" After five grueling hours under the scorching sun, I finally found the key. But at that very moment, a wave of exhaustion washed over me. I left behind signed divorce papers. Before leaving, I sent my son one last message. [Don't worry. You won't have to put up with a terrible mother like me anymore.]
