One moment I'm chasing after a rabbit and the next, I'm falling down a rabbit hole! What the heck?! This ain't Alice in Wonderland?! Though as I opened my eyes, I soon found out that I was no longer in my original body and that somehow I transmigrated into the light novel, A Fairytale Romance. And that isn't all, the character whose body I transmigrated into... is none other than the canon-fodder, stuck-up, arrogant, and selfish ojou-sama who was nothing more than a comic relief character, Maria Rosendrey. Life truly sucks...

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.
