One day, Sylena Erden suddenly regains memories of her past life, and remembers the story of a romance fantasy novel.

In that story, she's the villainess, destined to be executed for using forbidden black magic.

But the accusation that seals her fate began with a noble lady's mana poisoning incident, and Sylena suspects there's more to it than the rumors suggest.

She refuses to let herself be condemned for a crime she didn't commit. With her protective father and teasing sister at her side, Sylena sets out to uncover the truth and clear her name before the imperial ball, where she intends to expose the deception behind the accusation.

The Empire's villainess? Apparently, that's her. But she's not about to follow the story to its ending.
