The Villainess' Journal: Newlywed Life of an Obsessive Researcher

“Will you marry me, Villainess Estelle Aublanc?” Estelle, a viscount’s daughter with a passion for science, loves nothing more than to conduct research in her field of expertise—magic circles. But one day, the “Ice Marquess,” Gerald, proposes marriage during their very first meeting. Her father explains that this man wants to share his life with the “ultimate villainess,” as she’s known throughout high society. But that nickname wouldn’t exist if her little sister hadn’t gone around misbehaving while using Estelle’s name! As she leaves for the marquess’ house, still unsure of what to make of the arrangement, Estelle’s father threatens to burn up all her research materials if this new marriage ends in a divorce. “That leaves me no choice. If I don’t become the villainess he’s looking for, all of my data will be destroyed. How did it ever come to this?” Estelle decides to live as a villainess to protect her precious research, all while keeping a journal of her daily life at the home of the Ice Marquess.
