Read Manhwa The Hero Became the Duke’s Eldest Son:

It was Aden Albireo, dubbed “The Dragon Slayer,” who vanquished the Demon Lord and, in the end, preserved the planet. But those who professed to be his friends deceived him, and he was left for dead. “I never imagined that I would survive again!” The rash oldest son of the Duke, “Aden Albireo,” who was unknown and invisible until 15 years before the Demon Lord’s resurrection, has reappeared in the form of “Aden Remes”! Additionally, what’s more “It’s been a while, Dragon King!” Is it the Demon Lord in my soul that I believed I had killed? Can Aden stop the Demon Lord from rising again and put an end to his awkward cohabitation?
