Lucia Rue Clier Chanoban, a princess of the Chanoban Kingdom, has grown up imprisoned in a tower after a coup deposed her father, the former king. One day she is dragged out of her cell and told she must marry Ricardo von Born Ormung, the terrifying Cold Emperor of the Ormung Empire, in place of her cousin Marguerite. The marriage is purely political: a loveless union meant to produce an heir. Lucia endures a distant husband, pregnancy, and childbirth, yet she finds her first true happiness in raising her son, Keith. Her position remains weak, and Marguerite, who wants to seize Lucia’s status and child, sends an assassin who kills Keith and then murders Lucia.

At the moment of her death, a miraculous power rewinds time, sending Lucia’s consciousness back to the moment she was still imprisoned in the tower. Armed with knowledge of the tragic future, she resolves to prevent the assassination and protect her son. She agrees to marry Ricardo once more, but this time she discovers that the emperor she believed to be ruthless and emotionally cold harbors an unexpected, caring side. As she navigates court intrigues, her own growing bond with Ricardo, and the looming threat from Marguerite, Lucia seeks to forge a different destiny—one where she can keep her child safe and uncover the truth behind the empire’s secrets. The story follows her second chance, blending romance, political maneuvering, and the emotional stakes of a mother fighting for her family.
