In a world where reincarnation is a reality, Rishe Irmgard Weitzner's journey spans not one, but seven lifetimes. From the humble beginnings of a pharmacist to the trials of a knight, Rishe has experienced a kaleidoscope of lives, each one cut short by the ravages of war. Now, in her seventh reincarnation, she yearns for a life of luxury and tranquility, far from the chaos that has plagued her past. However, fate has a twisted sense of humor, as the key to her lavish dreams lies in the hands of the very man who ended her previous life—the crown prince of the Galkhein Kingdom, Arnold Hein. Rishe's path to a life of ease is fraught with challenges, as she must navigate the complexities of a royal marriage to a man destined to become a tyrannical ruler. Armed with the knowledge and skills acquired from her past lives, Rishe must unravel the mysteries behind Arnold's brutal actions and find a way to prevent the impending war that threatens to engulf the land once more. With each step, she draws upon the experiences of her previous incarnations—the shrewd negotiation skills of a merchant, the compassion of a doctor, the humility of a maid, and the bravery of a knight—to forge a new path in her seventh life. As Rishe embarks on this uncharted journey as the bride of an enemy nation's crown prince, she must use all her wit and cunning to not only survive but also to alter the course of history and secure the peaceful future she so desperately craves.
