Prince Kevin, a pure‑blood vampire, and Raina, a half‑human hybrid, were about to seal their engagement with a sacred blood‑oath ritual. But a brutal vampire clan war shattered their future. Raina’s brother indirectly caused the death of Kevin’s younger sister. To shield Raina, Kevin was struck by the Shadow Blood Curse and fell into a deep enchanted slumber. Taking advantage of his coma, Kevin’s family drove the pregnant Raina far away from the realm.
Five years later, Raina returns as the Creative Director of the International Vampire Alliance. When Kevin spots her traveling with her friend Leo and Leo’s little daughter Molly, the girl calls Raina “Mommy”. Misunderstanding grips Kevin — he believes Raina has built a new family with another man. Torn between lingering love and bitter resentment, the pair are trapped in painful emotional entanglements, pushing each other away while still caring deeply for one another.
Gradually, the truth unfolds. Kevin discovers Raina secretly gave birth to his son Keane all those years ago. He also learns that his own mother Isabella had fabricated lies and forced Raina to flee five years before.
On the magical full‑moon night for vampire blood‑oath ceremonies, Kevin kneels before Raina in front of their friends. Swearing upon his own royal blood, he proposes the lifelong blood bond. Raina accepts his vow. Their blood‑oath marks the end of all misunderstandings. At last, the whole family — Kevin, Raina and little Keane — reunites and lives happily together.
