Anjou, 1151. Baudouin, a proud young squire, was summoned home from the court of Henry Plantagenet to claim a fief—and to marry Aloïs, a high-born woman whom he had loathed since childhood. But Aloïs was no ordinary bride: by day, she kept her place in courtly society; by night, she disguised herself as a man and hunted down thieves and brigands threatening her people.

Forced into marriage, Baudouin and Aloïs clashed fiercely. Yet as the kingdom teetered on the edge of war, their destinies intertwined. Baudouin joined Henry in his campaign to seize the English crown, while Aloïs faced threats within her lands and from her past. Old traumas, secret alliances, and looming betrayals pushed both towards transformation.

As passion slowly replaced resentment, each had to fight for a place in a world that punished defiance—especially from a woman who dared to wield both sword and will. From the forests of Anjou to the battlefields of Normandy, The Twin Blades is a sweeping tale of power, resilience, and forbidden love, inspired by the emotional depth and pace of historical K-dramas.
