Abandoned on the palace steps of Solaria as an infant, Y/N should have been forgotten by history. Instead, she was found by a servant and brought before Queen Luna, who made a shocking decision: to raise the mysterious baby as her own daughter alongside Princess Stella. For sixteen years, Y/N’s origins remained a mystery. The only clue was the strange celestial mark on her shoulder—a mark that glowed whenever she used magic. Now, as a first-year student at Alfea, Y/N must learn to control powers no fairy has possessed in centuries. She is a Celestial Fairy, capable of manipulating stars, moonlight, supernovas, and even black holes. But while Y/N struggles to uncover where she came from, someone else becomes her biggest problem. Riven. The reckless Specialist is drawn to her from the moment he sees her. What starts as fascination quickly becomes something deeper, stronger, impossible to ignore. Because Y/N isn’t just another fairy. She’s his soulmate. And fate has plans for both of them.
