Dietrich, widely known as the "Cold-Disaster Prince" for his apparent inability to show warmth, was thrust onto the throne at the age of seventeen under the guiding hand of his ambitious mother. However, his reign ends in devastating betrayal when his younger brother, Oscar, seizes the crown and condemns him to a public execution. Yet, at the precise moment the blade falls, Dietrich’s consciousness is miraculously hurled back through time, awakening once more in his thirteen-year-old body, four years before his tragic fate. Armed with the agonizing memories of his previous life, Dietrich resolves to rewrite his story. Above all, he vows to cherish Marguerite, his devoted fiancée. In his first life, he repaid her unwavering loyalty and quiet prayers with nothing but cold indifference, pushing her away even as she remained by his side until the very end. Now, fully aware of the profound devotion he discarded, he is determined to protect her and correct every mistake that led to his downfall. Thus begins his journey of redemption and retribution—a path destined to transform the despised prince into a ruler forever remembered as the "Wise King."
