The Masked Villain Wants to Marry Me

From the back cover

"You have no option but to accept my offer, Estelle," Raziel said, his eyes flashing red.

Lady Vienna's only desire was to be with the story's male protagonist. Not until a mage appeared and handed her a book one day. The book, it turns out, contains the flow of her life! She even assumed she was the female lead, yet she was the story's villain! When she learns that she will be murdered by the villain, Duke Raziel, at the age of 22, she does everything she can to prevent it!

She gets closer to the villain and learns his secret, which causes him to propose her a marriage contract when she discovers the truth about the male lead's actual nature. In most stories, villains are killed, the male and female leads marry, and they live happily ever after; however, Lady Vienna "Estelle" Thaleia Xaviera defies this pattern.

It is up to Vienna to prevent poisonings, death threats, betrayals, and assassinations from occurring as a result of the book. "It's better to adore a villain since we know he'd do everything for you. The hero, on the other hand, would be willing to give up your life for the sake of the greater good.”
