Rebirth in the novel as a character I hate

Kintaka never expected that he would die in a stupid way by Truck-kun, as if he were in a cheap Isekai anime. ​But what he truly didn't expect was to be reborn as Ethan de Rosemont! ​A miserable side character in a famous novel, possessing a handsome appearance and being the beloved son of Duke Albert de Rosemont. ​Rich, handsome, with a transcendent talent, and an unbeatable power that easily makes him the strongest. ​Everything was good, but... Kintaka hated Ethan. ​Why? Well... read the story and you'll find out! #Isekai#Reincarnation#Transmigration#Magic#Fantasy#Action#Adventure#WeakToStrong#System#OpMc#Overpowered#Nobles#Royalty#Drama#CourtIntrigue#SecretIdentity#Rebirth#SideCharacter#AntiHero
