I’m Trying to Become Part of the Dark Duke’s Family

I was reincarnated into a novel. And not just anywhere—I was reborn as a terminally ill character with the same rare disease as the female lead. In the original story, the male villain eventually finds the cure for her… But I die before the story even begins. Lowena decides to act early. Before the villain completely loses himself and lives like a shell of a man, she plans to snap him out of it and make him obtain the cure sooner. “Hello, Your Grace. I’m from the Townsend Orphanage. My name is Lowena Wheatfield, and I’m ten years old.” “…What?” “If you take me in as family, I’ll run to the front door to welcome you home every time you return.” “What nonsense is this—” “And this… I’m only saying it because I’ve really worked up the courage.” “…Now what?” “I’ll even give you a goodnight kiss before bed.” I decided to become part of the villain’s family.
