Jill, a noblewoman, faced a tragic fate when her fiancé, the Crown Prince, ordered her execution. However, at the brink of death, she found herself transported back in time to the night of their engagement party, six years prior. Determined to alter her path and avoid the impending doom, she impulsively proposed to the man standing behind her—none other than Emperor Hades, her greatest adversary. Despite knowing his future descent into darkness, Jill quickly retracted her proposal in panic. Yet, Hades, intrigued by her actions, brought her to his palace and began to care for her, even preparing meals for her himself. Captivated by his unexpected kindness and with her heart set on changing his destiny, Jill resolved to lead him toward a brighter future. "I will ensure you find happiness," she vowed, embarking on a journey to rewrite both their fates and rebuild their lives from the very beginning.
