Prior to her birth, Won and Hyun Bin made a bet regarding the gender of her child. If the child is a boy, the king shall select her as the bride for the royal wedding. On the other hand, if it is a girl, she shall grant him the land she inherited, amounting to at least one-third of Seo Seo. Won bet for the child to be a princess, while Hyun Bin chose it to be a prince.
Bridal Selection Arc
As Hyun Bin gave birth to fraternal twins, neither she nor the king won their bet in guessing their child's gender. Nonetheless, Jin Won decides to make the royal consort as the third bridal candidate for the royal wedding, since he could not find his original choice for the selection.
During the bridal candidacy, one of Hyun Bin's servants finds her twin brother dead in his sleep due to poisoning. The prince's death takes a heavy toll on Hyun Bin; the ministers and servants brand her as crazy, mentally unstable, and unfit to further take part in the bridal selection. Moreover, because of her apparent insanity, the ministers, particularly spearheaded by Yoo Ja Gyeom, decide to take the baby princess away from her mother.
Hyun Bin overhears of such scheme from her servants and, in a frenzy, rushes out to see her baby princess, who now appears to cry in her hallucinations. The king, knowing the ulterior motive of the ministers, shuns them and asks for Hyun Bin's wish after losing to her in a game of rock-paper-scissors, similar to when they were younger. She wishes to stay with the king and her baby princess, which the king ultimately grants.
Crimson Moon Rebellion
As the rebel army's revolt commences, Baek Ju and Baek Lin notify Heuk Rang that Hyun Bin and her daughter are not in their quarters, suggesting that someone else might have gotten to them first. Heuk Rang then assigns Baek Ju to locate them. In the end, Rei and her daughter are seen after the successful revolt by the rebel army, in which Yi Jeok ascends to the throne. With the death of Jin Won, Rei and her baby princess are seen in a carriage with Rok Ha, possibly traveling to Seo Seo, though their fates remain ultimately unknown.
- The Yi family had various cases of having twins. The baby princess had a twin brother, her paternal grandfather had a twin brother, and her father's half-brothers are twins.
