I Can’t Die Before the Novel Even Starts

Under the sacred vows made in the name of the divine, I entered into an arranged marriage. But during the ceremony, my memories from a past life came flooding back. I realized something horrifying: I’m a character who dies even before the main story of this novel begins. And not just any death—an assassination that the book barely even bothers to describe! Why?! By whom? When? Where?! How am I supposed to figure out how I die? Who can I even ask about this?!
