転生侯爵令嬢奮闘記ーわたし、立派にざまぁされてみせます！

ある日突然、前世の記憶を取り戻し、今世での自身の振る舞いを省みた侯爵令嬢ユリアンヌ。贅沢三昧に弟妹いじめ、婚約者へのつきまとい……。悪行の限りを尽くした彼女のゲスな性格と肥えた見た目は、前世で読んだ小説の悪役令嬢そのものだった。どうせこの先〝ざまぁ〟される運命なら、身も心も綺麗にしてからがいい！　そう考えた彼女は、ダイエットと共に全力の家族孝行を始めて――!? One day, Julianne, the daughter of a Marquis, suddenly regained her memory of the previous life and realized how dreadful her behavior was in this world. Bullying her brothers and sisters, messing around with her fiancé… She has been doing her best to do bad things. Her personality is awful. What’s more, she’s fat and ugly – just like the villain daughter of the novel I read in my previous life. Only a dark future awaits her. “If you are destined to be fooled, you should clean your body and soul.” With that in mind, she started her family filial piety with all her might along with her diet. “I’ll earn a lot of money for my family, ohhh!”
