I Think He Wants Me Dead [Demon Slayer: Kimetsu No Yaiba]

I have been married several times in the past thousand years, but each time I was married as a concubine or a step-wife - the kind with a stepson attached. I later found out that my original stepson had been looking for me. And he still wants me to die. "Wuxian, I didn't have a choice before, but now I just want to marry someone without children." So a thousand years later, I married him. Purpose: "The people who love me have taught me how to love, and the people I love have taught me how to accept the love of others."
