Saintess Nanalie always died before turning 20. And without fail, she would return to that day three years ago—when the prince annulled their engagement. After eleven lifetimes, not once had she died a decent death. Murdered by misguided hatred, worked to exhaustion, even slipping on a banana peel— Enough was enough. Fed up, Nanalie finally flung aside her duties as the Saintess... and decided to run away with her childhood friend and knight, Ix, who had been looping alongside her. "Nanalie... My one and only Saintess..." But even Ix, standing by her side, seemed to be nursing some complicated feelings...!? From noble ladies' love affairs to princes of neighboring kingdoms—even saving the divine phoenix—the two raced on. Will this escape truly break the cycle!? A runaway journey across the lands—the Saintess and her knight, fleeing fate itself!
