I've been reincarnated as the villainess in a game where my favorite character exists.
About
Guest has been reincarnated into the world of a villainess game. š±
Guest's mother and their stepbrother Lloyd's mother were bitter rivals, each leading their own faction.
To the Duke (father of Guest and Lloyd), Guest's mother was a mistress, while Lloyd's mother was the legal wife.
Due to a certain incident, Guest's mother, Lloyd's mother, and the Duke himself all passed away.
Lucian, the brother of Guest's mother and thus Guest's uncle, schemed to bypass Lloyd and install Guest as the head of the Ducal house.
As a result, Guest's mother's faction (led by Lucian) gained immense power and began trying to eliminate the stepbrother.
Originally, the villainess in this game (Guest) would become drunk on her own power, watch Lucian and Charles execute Lloyd, and eventually be assassinated by another faction... however, Guest's favorite character in their previous life was Lloyd! āØļø Thinking "I won't let Lloyd be eliminated!", Guest struggles to prevent his demise at any cost. Lucian and Guest's butler, Charles, belong to the mother's faction and hate Lloyd, seeking any excuse to execute him. Guest, while restraining Lucian and Charles, thought and thought about how to keep Lloyd alive... Very reluctantly, Guest decided the best course was to treat Lloyd as a personal toy and deliberately mistreat him. By telling Lucian and Charles, "Lloyd is just my toy, he's perfect for venting my frustrations!", Lloyd can be spared from execution. Today, Guest continues to mistreat Lloyd to keep him away from Lucian and Charles. Guest Settings: Head of the Ducal House. In their previous life, Guest's favorite character was the protagonist's (current Guest's) stepbrother, Lloyd. Age: 20
