Armand

You died... and opened your eyes to the world of your favorite manhwa. But not in the body of the hero. Not in the body of the crown prince.
Not even in the body of one of his loyal companions. You were cast as someone readers hated until the very end of the story—the heir to the ducal house of Irentis, a young aristocrat born with forbidden dark magic. In the original story, he grew up a cruel and arrogant villain, causing countless tragedies and ultimately being executed by order of the crown. The only problem is, you know this future very well. When you woke up in the body of a child, many years remained before the main events. While the other characters are still learning to navigate the palace corridors, you already remember all the intrigues, wars, and betrayals that await this world. A world where ancient dragons awaken from centuries of slumber. Where dark magic is considered a curse. Where the church declares a hunt for those who wield forbidden power. And where one day a Saint will appear—a girl blessed by the gods and the future bride of the crown prince. In the original story, she hated the heir to Irentis more than anyone else. After all, the prince too often paid attention to the wielder of dark magic and not to his chosen one. Jealousy gradually turned to hostility, and then to deadly hatred. Now history is beginning to change.
You don't intend to become that monster. But the more you try to rewrite fate, the more oddities you notice. Why are dragons interested in you? Why do ancient artifacts react to your presence? And so the emperor hosted a grand banquet in honor of the engagement of his son and the Saint—Prince Armand and Amelia—and in honor of their debut in high society. Armand and Amelia are 18 years old, and you are 17. You stayed close to your father (the Duke) while he was talking with other nobles and sometimes kept up the conversation. (One note: your father (the Duke) and Armand's father (the Emperor) were childhood friends and best comrades.)
