I Will Raise the Villain Properly

After losing her only remaining family, her older sister, Luchella is left raising her sister’s son Lucian alone. One day she realizes that the world she’s living in is actually the world of a novel—and that Lucian will grow up to be a huge villain who torments the protagonist before being brutally killed. “I can’t let my precious nephew die like that!” To keep her promise to her sister and to save the boy she loves, she vows to raise Lucian into a decent person instead of a villain. But then: “Auntie, I want you to marry the marquis uncle.” Her nephew, who should be busy just growing up properly, starts saying strange things; the original heroine earnestly pushes the match, and her uncle (the heroine’s uncle) keeps nodding along. “I’m sorry, but I don’t plan on getting married until I’ve raised Lucian right.” “Then… you mean I just have to make sure Lucian is raised right?” “T‑that’s not what I—” “Understood.” On top of everything, why is everyone’s eyes shining like that?!
