Elina thought she had hit rock bottom. She lost her job. Her therapy session dredged up memories of the ex-boyfriend who stalked and traumatized her. The only thing she had left to look forward to was the finale of her favorite fantasy series, Moonbound Faith. Then the show ended. The heroes won. The villain died. Everyone got their happily-ever-after. That same night, a knock at her door shatters what little peace she has left. Her ex is standing outside. The man who was supposed to be in prison. Forced to flee into a storm, Elina runs until she reaches the edge of a cliff with nowhere left to go. Faced with a choice between death and returning to the man who destroyed her life, she jumps. But instead of dying, she wakes up inside Moonbound Faith. Not as the heroine. Not as a side character. But as Luna—the infamous villainess whose tragic death she celebrated only hours before. Determined to survive, Elina plans to use her knowledge of the story to change her fate. But everything she thought she knew begins to unravel when a small boy tugs on her sleeve and calls her one word: “Mom.” The original story never mentioned a child. And when Elina uncovers the truth behind his existence, she realizes something terrifying. The villainess was never the villain. The story lied. And the ending she remembers may not be the ending waiting for her at all.

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.

I woke up inside a novel, and not even as an important character. I became a pretty background extra in a smut novel. My brother, however, was the only normal person in the entire story. His character setting was the one man the soft, delicate heroine could never win over. He was the cold, unattainable Prince Charming she could never conquer. When the heroine cried and confessed her love, he was studying. When she offered him her whole heart and body, he was busy starting a company. When she spiraled into scandals and nightlife, he was already a billionaire, calm and untouchable. I thought he would live a quiet, ascetic life forever. Until one night, I walked in on him at midnight… holding a piece of clothing I recognized all too well, murmuring a name over and over, a name so familiar that my scalp tingled.
