死に戻りの冷害王子が賢王と呼ばれるまで～導いたのは不器用な侯爵令嬢の祈りでした～ raw 第01巻

Dietrich, nicknamed the “Cold-Disaster Prince” because he seems incapable of warmth, became king at 17 under his ambitious mother’s influence. But life turns tragically cruel: his younger brother Oscar seizes the throne, then he is publicly executed. Miraculously, at the very moment of his beheading, Dietrich’s consciousness returns to when he was 13—that is, four years earlier. With that memory, he resolves to right his mistakes: this time he will cherish his fiancée, Marguerite. In his previous life, he pushed her away with coldness—even though she stayed loyal and kind until the end, praying for him. Now, knowing what he lost, he vows to do everything differently. Thus begins his revenge, his path to being called the “Wise King.”
