Migawari de Totsuida Reikoku Kokuou wa Hatsukoi Aite deshita

At twenty-eight, Kanae Yano has long resigned herself to a quiet, unremarkable life—single, unmoored, and untouched by the sort of grand romance she once dreamed of. That all shatters in an instant when she is abruptly summoned to a world of magic and nobility, torn from her modern existence without warning or explanation. There, she is met by Duke Zach Skrein and his daughter Rita, a striking young noblewoman whose face is an almost perfect mirror of her own. They present Kanae with a desperate, impossible plea: to become Rita’s body double and marry King Eugene Eistalotte, a sovereign so ruthless he is known across the land as the "Cold-Hearted Wolf." With the magic that brought her here incapable of sending her back, Kanae finds herself trapped in a foreign world with no choice but to accept this perilous fate. As she steps into the opulent yet foreboding courts of the king, Kanae braces herself for a life of servitude beside a man whose cruelty is legendary. Yet the moment their eyes meet, her carefully constructed walls begin to crumble. The tyrant standing before her is not the monster of rumor, but someone she never expected to see again—a cherished face from her past, a first love she once thought lost to time. What unfolds is a sweeping fantasy romance, where the collision of a familiar heart with an unfamiliar throne forces both a king and a commoner to confront the truths they have buried. In a kingdom where every smile hides a blade, Kanae must navigate a treacherous political landscape, all while struggling to understand the man she thought she knew, and the dangerous feelings that still linger between them.
