I'm Terminally Ill, and the Ceo's Wife Tortures Me Every Day

In a car accident ten years ago, I was the culprit who killed the parents of my childhood sweetheart... Since then, my life has become a dark purgatory. Five years later, my childhood sweetheart and I became legally married. I thought she was the dawn of hope, but unexpectedly, she turned out to be the executioner... I was a struggling animal waiting to be slaughtered, and she was the butcher enjoying this moment of joy. She repeated it every day, cut open my heart, and made a video of my most unbearable memory to play on a loop. Fortunately, I am finally going to die...
