In my previous life, on the day my sister and I attended the Witch Covenant's mating ceremony, I saved a fallen vampire prince. To repay my debt, the prince, upon returning to his clan, immediately declared that I would be his future bride. A year later, I gave birth to a pureblood heir—the only successor of the entire vampire lineage. The prince was overjoyed. On the day of his coronation as King, he sealed a blood bond with me, declaring me his eternal companion and queen. From that moment, I was revered by all races. My sister, meanwhile, chose a powerful werewolf Alpha, only to fade into obscurity as one among his many lovers. Her jealousy of me spiraled into madness. During a full-moon ritual held by the witches, she pushed me into an abyss, leaving me to die from the fall. When I opened my eyes again, I saw her running toward the direction of the vampire prince's misfortune on the very day of the mating ceremony. I knew then: she, too, had been reborn. But what she didn't realize was this—becoming the prince's bride was easy. Winning his heart, bearing his child, now that was as impossible as climbing to the heavens.
