During Rena Rubel's formative years, she felt isolated as her parents, the marquis of the north and his wife, raised her alone. However, her fortune changes when her parents reunite with her. But on the night before her twelfth birthday, her father betrays her by selling her off to an enigmatic man, obliging her to serve as a sacrifice.
Years later, while journeying to the capital, Lin rescues Rena and her maid, Yuni, from a group of miscreants. After sharing a meal with them, Lin is astonished to learn that Rena is not just a pretty facade. Instead, she is more potent and perilous than she appears.
The once innocent child is replaced by a tenacious Rena, who returns to find her father and pass judgment on his worthiness of her forgiveness. If he remains the same heartless rascal who discarded her, Rena pledges to ensure that he undergoes the same torment that she endured.
