Aden Albireo, known as "The Dragon Slayer," was the hero who defeated the Berserker and the Demon Lord, ultimately saving the world. However, he was betrayed by those who had sworn friendship and left for dead. "I never thought I'd come back to life!"
Fifteen years before the Demon Lord's resurrection, the once obscure and unseen eldest son of the Duke, "Aden Albireo," has returned in the body of "Aden Remes"! And what's more… "Long time no see, Dragon King!" The Demon Lord he thought he had slain resides within his soul?!
Will Aden be able to end his uncomfortable cohabitation(?) with the Demon Lord and prevent his resurrection?

The manhwa The Hero Becomes Duke's Eldest Son is an enjoyable read with engaging plotlines and minimal cringe moments. The Main Character shares similarities with Lloyd Frontera from The Greatest Estate Developer.
The central theme revolves around revenge, and the Artwork Is A Solid 9/10. Notably, there are no overly Annoying Female Characters, which is refreshing compared to many other manhwa. It's highly recommended for fans of Revenge, Regression, Demon Lord, Betrayed MC, and System-themed stories.

Review as of the end of Season 1, Chapter 54]Idiot South Korean author again... I curious if South Korean mentality are not only RACIST for other Asian Country, but also coward garbage mental.
THIS MC IS GENUINELY SO UNHINGED I FUCKING LOVE IT
++ the art the way some of their expressions are drawn is fucking brilliant no joke it’s so funny — kinda giving me the same shitpost/meme vibes as “the greatest estate developer” manhwa 😝😝 I love it
Regression, demon lords, hero party, villainous noble, evil mascot, these are done alright at least.
But then the authors heard that Lloyd, with his "slave collecting" and "facial expressions" tropes, is the latest trendy thing. And they managed to ruin it, by literally placing it everywhere without any sense or reason behind it. Even though a lot of recent manhwas have done exactly that, flawlessly.
Not to mention the mediocre art. Too bad I'd still continue reading this slop because I'm too weak to stop consooming.
