Why Do Readers Love The Devil Heiress Returns Main Character?

She underwent a death experience—at the hands of the family she cared for most, who then sold her off. At eight years old, Seraphina Valeza was adopted from an orphanage by the Hawthorne family, a run-down third-rate family in Lunada City. She lived for fifteen years there, always careful, thankful for a house that was not her home. She was an excellent student, kept her sufferings to herself, and obeyed them in return for their "kindness." When the Hawthorne family was on the verge of bankruptcy, they chose survival over conscience. Seraphina was forced to marry Julian Moreau, the heir of a second-rate elite family. The marriage was hell. Behind closed doors, Julian humiliated her, controlled her every move, and crushed her dignity. In public, she was paraded as a trophy wife; in private, she was nothing more than a disposable tool. Once Julian seized full control of the Hawthorne family, Seraphina lost even her last value. With no way out, she resorted to suicide. But destiny wanted otherwise and gave her another chance. She found herself in the same spot as she was on the day of her marriage. This time she did neither crying nor begging. Instead, she smiled and switched the groom. In front of stunned guests, Seraphina walked past Julian and stopped before a man sitting casually at the banquet table, dressed out of place and enjoying the food as if the wedding had nothing to do with him. Lucien Cross. The annoying guy she constantly quarreled with in college. The man who cried while carrying her dying body in her past life. The one whose love she came to realize onlqy when it was too late. This time, Seraphina will not let him go. And all those who wronged her will be punished, without exception.

She died once in fire while the man she loved watched her burn without a single step forward. Elena Vale was the villainess of a romance novel—written to be hated, destroyed, and discarded at the end of the story. And she did die exactly like that. Until she woke up at the beginning of it all. The night of the Arden Charity Gala. The night everything was supposed to start. This time, Elena remembers everything—every betrayal, every humiliation, every moment she was written to lose. But instead of begging for survival… She chooses revenge. Because if the world insists she is the villainess, then she will become one they cannot control. A woman who does not beg for love. A woman who builds power instead of tears. A woman who turns her ending into a beginning of destruction. And as she rises, something strange begins to happen. The male lead who once ignored her starts watching. The heroine who was supposed to replace her starts trembling. And the system that once promised her survival begins to warn her: [WARNING: Villainess behavior exceeds original plot limits.] But Elena is no longer afraid of the story. She is rewriting it. And this time… she will be the one they fear.

After I married Riccardo, the Don of the Moretti family, he paraded a string of mistresses in front of me. He never gave me a second glance. But on our tenth anniversary—right after my father’s death—he suddenly promised me half of his empire. The catch? In return, he planned to seize control of all my family’s arms-dealing routes. That pissed off his favorite mistress. She cornered him on his yacht, demanding he take his words back. Then she fell overboard and died. An “accident.” After she died, Riccardo went insane. He took it all out on me. He tied me to the back of his yacht. He dragged me through the sea, a human anchor, until the rocks shattered my legs, crippling me for life. I became the family’s shame. Then, as I lay helpless, he finished the job with poison. Then I opened my eyes. I was back on the day Angelo Marino—the head of our rival family—proposed to me. In my last life, my family forced me to say no. He came for me, a one-man army. He killed Riccardo, but died in the process. This time, I looked at his kind face and nodded. Yes. But as we embraced, Riccardo appeared. He ripped me from Angelo's arms and claimed me as his own. That’s when I realized the cruelest joke of all. My monster was back, too.
