Sinopsis

After a traffic accident, she wakes up inside a romance fantasy novel as the half-sister of the story's future villain. Determined to prevent that villain's dark turn, she pours everything she has into steering her sister toward happiness — only to find herself hopelessly entangled with the Grand Duke Rexvill, a man with a fearsome reputation as a bloodthirsty killer. He corners her whenever she's near another man, interrogating her like a jealous lover, yet when she dares to ask whether he might have feelings for her, he flatly tells her she's talking nonsense. So why, exactly, does he seem so obsessed with every detail of her personal life?
