Who Made the Head Maid Regress?

After serving the Crown Prince with utter devotion only to be betrayed and killed, head maid Amy returns to the past burning for revenge. She attaches herself to Noah—the Second Prince and the Crown Prince’s sworn rival—and dedicates herself to raising him into a powerful heir capable of toppling her enemy. But Amy soon realizes she possessed three magical tools at the moment of her regression, and the jewel Noah gifts her may hold the key to her second chance. Before she knows it, her carefully laid path of vengeance veers wildly off course when Noah—now a prodigious Swordmaster and devoted adult—kneels before her and proposes, transforming what should have been a tale of revenge into an utterly unexpected romance.
