Five years ago, Hailey Penn and Damon Mercer are lovers, but Damon conceals his identity as heir to one of the capital's most powerful families, working undercover as an ordinary employee at his family's branch office. They break up due to a misunderstanding, and Damon suddenly vanishes. Hailey gives birth to their son Cody and struggles as a single mother for five years. When her job transfers her to the capital city Esrane, she unexpectedly reunites with Damon at a business dinner. They clear up their misunderstandings and finally build their happily ever after.

The vampire leader Bastian falls victim to a plot, triggering the Blood‑Bond Curse. By a twist of fate, he has a one‑night stand with Aurora, who is terminally ill. Bastian soon discovers that Aurora can ease his curse‑induced attacks, so he proposes a contractual marriage to her. Overwhelmed by chaotic circumstances and unable even to afford her mother's medical bills, Aurora accepts out of desperation. Living under the same roof, Bastian begins to suspect that Aurora carries the Witch‑Gold bloodline capable of lifting the Blood‑Bond Curse. He also realises she is no ordinary girl, but one blessed with immense hidden power. Eventually, the two unlock their sealed memories, and the wheel of fate finally brings their love — torn apart against their will three hundred years ago — to a happy conclusion.
