Dieterich, known as the “Cold Calamity Prince” for his ice-cold inability to understand human emotions, ascended the throne at just seventeen, obeying the will of his power-hungry mother.
But fate was cruel.

In time, his younger brother Oscar, beloved by the people for his radiant, sunlike smile, seized the throne—and Dieterich was publicly executed.
Yet at the very moment his head was severed, Dieterich’s consciousness returned to an impossible place: four years earlier, when he was thirteen.

Had time been rewound?
He could still feel the sensation of being beheaded.

Perhaps it was a whimsical miracle granted by the goddess Dahlia, but if he had been given another chance, Dieterich resolved to do one thing right this time: make his fiancée Marguerite happy.

In his previous life, he never knew how to love.
Because he cherished her so deeply, he deliberately treated her coldly, pushing her away.
Yet no matter how much he hurt her, Marguerite remained kind—and even in his final moments before execution, she prayed for him.

This time, he will not make the same mistake.
He will survive at all costs and claim happiness together with Marguerite.

Thus begins the revenge of the prince who would later be known as the “Wise King.”
