Transmigrated as the Cuck.... WTF!!!

streak of being publicly humiliated in every story route. In other words, he was the designated cuck of the game Academy of Roses.Too bad for everyone, Cassius is now possessed by Arawna burned-out gamer who just tried to kill himself after exacting savage revenge on his sister's cheating husband.Waking up in the body of the most pitiful character in eroge history? Not ideal. Finding out his missing sister has also been isekai'd and is now pretending to be Cassius's noble "sister" to avoid suspicion? Wild. Realizing she's about to be married off in another forced engagement plot? Yeah, fuck no.Armed with system powers(everyone has it), broken stats(for your average joe), and a big 'sister complex'(Not Incest) on steroids, Arawn has one simple plan: Live a peaceful life with his sister, for it he would, Break the rules. Shatter the narrative. And if anyone tries to play the protagonist? Use them for his own plans.This time, the cuck's got teeth. And he bites backin the most painful ways.Warning: The MC is a villainous character, he is psychotic, manipulating, borderline insane and unhinged. So, please keep that in mind
