[Stepmother] ━━━ ⚜ ━━━ The MC reincarnted as Duke Cassius’ wife and new stepmother of Ain Spenner, the villains of a novel. Unlike in the plot where she abuses Ain and later dies by his hand, the MC decides to shelter him from all evil in hopes that he won’t become the villain he’s destined to be. But it’s futile. Ain and his father are already villains, but in order to keep her love, they try and hide their dark sides from her. Eventually she finds out and feels betrayed and foolish but decides she’ll love them regardless.
