With the Trillionaire System, he’ll rise from a forgotten nobody to the richest man in the country. Those who mocked him will kneel. Those who betrayed him will pay.

After transmigrating through three novels in a row, the hardest thing I ever suffer through is drinking iced long black. But when I open my eyes again, I somehow become the pathetic simp side character in a trashy romance novel. Just as I debate whether to file a complaint against the system, the trembling system hurriedly explains something to me. Although this is a trashy romance novel, it is also an unfinished abandoned novel. I ask, "So you're saying I decide how the story develops?" The system replied, "Yes. Everything is completely under your control." Satisfied, I lazily stretch and begin checking the original Jacob's background. He has a trillionaire father and a billionaire mother. On top of that, he has seven rich and beautiful older sisters. With such a ridiculously overpowered setup, how can he go around simping for a broke college girl with no money? What a complete waste!

Vera fought for her life in the apocalypse for ten years. Ten brutal years left her disfigured, hungry, and almost broken, but she still clawed her way through it. She killed zombies, ran from mutated animals, starved, bled, and learned humans were often more dangerous than monsters. Then her brother, the only family she had left, betrayed her. Vera thought death had finally come. Instead, she woke up inside a trashy book she once read to stay sane while the old world fell apart. A book with a twisted plot and too much drama. And because her luck had always been terrible, Vera did not wake up as the heroine. No, of course not. Her second chance was to become the hated second female lead, pregnant, unwanted, and written to die when the plot no longer needed her. Her babies were supposed to die too. Even the three men who got her pregnant were written as future corpses, all to push the story toward spoiled women and one psychotic male lead. But Vera was not the woman from the book. She had survived one ruined world. She had not walked through radioactive rain and eaten mutated food just to cry over fantasy characters or beg for love inside a stupid plot. So Vera adapted. She accepted her punishment, took her three unborn babies, and left for the garbage center without making a scene. Everyone thought she had been thrown away. Vera saw a chance to make money, protect her babies, and build something of her own. Now the woman meant to disappear is building a wasteland empire, breaking the plot, and driving three men insane because she no longer chases anyone. By every rule in that world, Vera should be dead. But dying a second time was never an option.

After transmigrating into a BL novel, she expects to become a forgotten side character and survive until the ending. Instead, she awakens as an SSS-rank Omega Guide, a rare Guide capable of calming dangerous Sentinels in the fantasy world of Elarion. Knowing the original story, she understands one thing clearly: she must stay away from the five powerful men destined to become the central figures of the novel—the cold Northern Duke, the ruthless Crown Prince, the obsessive Grand Magister, the dangerous wanderer of the Forbidden Forest, and the Forbidden Saint. They are not supposed to fall for her. Yet fate begins bringing them together. She meets each man in a different corner of Elarion, while every encounter slowly changes fate. What begins as curiosity gradually becomes attraction, protection, jealousy, and dangerous obsession. Determined to remain independent, she travels through enchanted kingdoms, ancient ruins, forbidden forests, magical academies, and lands ruled by terrifying creatures while uncovering the truth behind her Guide abilities. But something is wrong. The events she remembers from the novel are changing. Characters destined to die survive. People who were supposed to live disappear. The system guiding her begins hiding information, and the five men seem to know more about her. Then, the most mysterious of them all looks at her and whispers, “You finally came back.” She has never met him before. So why does he remember her? As secrets surface and ancient magic awakens, she discovers that the BL novel may never have been fiction. Her transmigration, the five men, her powers, and the system are connected by a secret capable of destroying the world. Now she must choose between following the destiny written for her or rewriting the story—even if it means becoming the obsession of five men who refuse to let her go.

When Alpha Jace Brown’s bride disappeared hours before their wedding, he chose me instead. Not because he loved me, because I was his mate but because I was convenient.

Only endless reminders that the title around my neck belonged to another woman. Then Jenna returned, the sister I trusted, the bride I replaced months ago.

By the time I realized the truth, my husband had already chosen her all again. So I left. But my disappearance didn’t end the nightmare, it began instead. Because the farther I ran from Babcock Pack, the more impossible truths I uncovered. The wedding wasn’t an accident, My miserable life wasn’t an accident. Even becoming the Substitute Luna…had been planned before I was born. Now the Alpha who cast me aside is searching every territory for the woman he lost. While the sister who stole everything from me will burn kingdoms to make sure I never return.
