He Gave My Daughter's Heart to His Mistress's Son

On Christmas Eve, Sloan was killed by her childhood friend Bryn and her fiancé Grant working in tandem. Bryn exploited her seafood allergy to gravely injure her, then hired someone to finish the job; Grant not only shielded the murderer but also spread vicious rumors, leaving her reviled even in death.

Unexpectedly reborn to the eve of the tragedy, Sloan—now seeing through every layer of the conspiracy—resolves to take revenge. She deliberately misleads Bryn by faking a peanut allergy, luring her into sprinkling crushed peanuts into the Christmas Eve dinner. Grant, who is fatally allergic to peanuts, goes into shock, and the first crack appears in their alliance.

She continues laying her traps, manipulating Bryn into burning the 400,000 dollars Grant had stashed to impress others. On Christmas Day, Grant is publicly humiliated. His mother and Bryn then gang up on Sloan to force her to surrender her jewelry, which finally extinguishes the last of her feelings for him. Sloan breaks up with him in public, revokes his high-paying job, and cuts off his lifeline.

Drowning in debt, Grant sinks deeper into gambling. With nothing left to squeeze out of him, Bryn cheats, gets pregnant, and flees with whatever money remains. Sloan anonymously tips him off, pushing Grant to commit murder—for which he is sentenced to life in prison.

Just as Sloan believes her vengeance is complete, a diary uncovers a deeper secret: Bryn carries memories of her past life, and the true mastermind is Grant's mother, Patty! She was the one who blocked the rescue in Sloan's previous life and has been pulling the strings all along in this one. She is the venomous serpent hiding in the dark.

Sloan gathers every piece of evidence and brings the case to court. Patty is locked behind bars.

Nathan, the emergency room doctor who also holds past-life memories and witnessed Sloan's death, has stood by her every step of the way. All the wicked reap what they have sown, and the era of hatred draws to a close. One harsh winter, Sloan finally walks free from the trauma of two lifetimes, finds peace at Nathan's side, and steps into a stable, complete new beginning.
