For all of you confused why the description different from the first few chapters, is because this is her past life before she reincarnated as the count's daughter.
@SilentWaters : This is the life of "Martina", i.e. the one who's the Empress mentioned in the description and before reincarnating into Beauty and the Beast.
Basically we actually get to see the 'badass reincarnate in the future' actually being badass instead of being told they were one.
