How to Perfectly End a Contract Marriage

In her previous life, Charlotte Noha relished the role of a villainess and took pride in her noble bloodline. She had married the empire's war hero, Duke Alfonso Linus Eduart, for the sake of her house, but she soon unexpectedly fell in love with him. However, Alfonso loved the sweet Adeline Laperouse, and when Charlotte wished to divorce him, her half-brother, Quincy, killed him. Charlotte obsessively searched for a way to revive Alfonso—and she succeeded. A magic spell sends Charlotte back in time before her marriage to Alfonso, but she has only a year to ensure that he is happy. As Adeline was previously Alfonso's happiness, Charlotte decides to intervene and eliminate all of his prospective brides until Adeline is the only choice, even if it shatters her own heart.
