Margaret Nuttall, a reincarnated villainess, had memories of her past life:

That this was the world of an otome game.

That she herself was a stereotypical villainess.

And, having enjoyed numerous reincarnation novels, manga, and games, she also knew that for a reincarnated villainess to find happiness, she had to employ every conceivable means to defeat the heroine.

...How bothersome.

Since I've been born a noble, I might as well enjoy some luxury.

Rather than abandoning luxury for a life of diligent effort, wouldn't it be better to live this short life as I please and then die?

This is the story of a reincarnated villainess who, having reached that conclusion, decides to live life completely on her own terms.
