It was at our engagement banquet that I finally learned the truth. I wasn't the true heiress of a noble human family. I wasn't the "fated bride" destined to bear a half-blood child for the vampires. I was just the wrong baby someone had brought home from the hospital. A fake. I'd thought that Alexander, the boy who'd risked his life to drag me out of a burning house, the boy I'd grown up beside, would love me the same as always. Instead, in front of everyone, he let go of my hand and looked down at me with cold eyes. "Without that bloodline, do you really think you deserve to stand beside me?" Then he reached out and slid the engagement ring off my finger himself. He turned, and led the true heiress up to the high platform. Everyone laughed at me. The fake heiress, delusional enough to think she could marry the vampire heir. I was thrown out of the only home I'd ever known. The only kindness left to me was Alexander's, a scrap of charity that let me stay at his side as the lowest thing a vampire could keep. A blood slave. And then, later, I died in an explosion. Saving him. Alexander knelt in the blood and lost his mind, screaming at everyone around him to save me. But there was something he didn't know. I hadn't died. Later still, at a vampire banquet, he saw me again at last. I walked past him on another man's arm, smiling. And this time, it was his turn to lose his mind begging me to look back at him.

The day I came back to the Bennett family as the real heiress, Romina, the fake one, looked at me with red-rimmed eyes and said she wanted to give the engagement back to me. "Don't bother. I'm already seeing someone." I rested a hand on my barely noticeable belly and said, half joking, "If you feel that bad about it, how about you just cash me out instead?" The words had barely left my mouth before a few lines of text drifted across my vision. [lmaooo the villainess is still scheming for money at a time like this. can we please skip ahead to the part where the male lead puts her in her place.] [I came for the sweet romance between the lead and the fake heiress heroine, not some side character throwing a fit because she's got a baby bump to wave around] [spoiler from me! the villainess gets thrown out of the family, the lead ends up hating her, and she dies in childbirth. throwing confetti!] I clicked my tongue. How could I possibly cling to a strange man? Then footsteps came from behind me. Romina walked over, crying, and introduced me. "Orlando, this is my sister, Ophelia. The engagement was supposed to be hers." I turned around, and my whole body went rigid. It was the patron who'd kept me for five years, the father of the child I was carrying.

As each finger was cruelly broken, the agony that surged through her body revealed the truth—her nanny and maids had betrayed her long ago. When her sister confessed to carrying her husband's child, Miranda realized that their prior kindness had been nothing but an act in a sinister play. When her gentle husband, a man she had once loved, directed his new lover to claim her life, she understood she had been nothing more than a stepping stone to his ascent to power... Twenty years in this mortal world, and she was merely a puppet manipulated by others. Yet, fate, in its mercy, offered her a second chance. This time, it was her turn to consign those deceivers to hell! Although she returned only to exact vengeance, how did she unwittingly capture the interest of a powerful magnate this time around? Watching the delicate yet resilient girl, the Duke turned to his subordinate and said “Remove the filth that marred her eyes. Feed it to the dogs."
