They Regretted It After I Sacrificed Myself

What I was proudest of was that I never revealed where my police officer father was, even when I died. I was even more thrilled that I died on my way to find the birthday present my father had gotten me. But when the criminal investigation expert wondered whether the headless female corpse was mine, my father sneered: "If she really thought she had the nerve to celebrate this birthday, then she deserved to die!" I suddenly realized that my father had played a joke on me that night. But he didn't know that his joke had killed the daughter he hated most.
