When Nezuro Hikaru, an undercover agent on a classified mission, hears a strange crash in the forest one stormy night, the last thing he expects to find is an unconscious girl glowing faintly under the rain. Her name is Misa Fynx - beautiful, mysterious, and definitely not human. She comes from another world, one where fox spirits are bound by fate and ancient vows. But when a twist of destiny tears her from her realm and drops her into the human world, her powers are weakened, her memories fractured, and her freedom threatened. Nezuro never believed in myths - until one started breathing in his safehouse. As he nurses Misa back to health, he's drawn into a secret far bigger than his mission: a love that defies worlds, and a bond written long before either of them were born. But the peace they find is short-lived. When Misa's past hunts her down - an ex-lover from her realm determined to reclaim his "bride" - both her heart and Nezuro's life are thrown into peril. A story of fate, forbidden love, and the fragile bridge between two worlds. Because even a fox spirit can fall in love with a human... and sometimes, love itself becomes the most dangerous magic of all.
