DUKE'S TRANSMIGRATION WIFE IS AN ASSASSIN

Cherry is a modern-day assassin betrayed by her closest friend during a mission. She woke up in the body of a side character from a novel that she last read. Celestine Lancaster is the side character and an illegitimate daughter of a southern duke. Her family abused her all the time, spread bad rumors about her, and forced her into a marriage with the monstrous northern duke, Athan Kingsley. Athan was famous in the Esclairk kingdom for his brutality and was also the emperor's younger brother. Thanks to those bad rumors about her, Athan never paid any attention to Celestine and always maintained his distance from her. Their relationship was far from any average married couple. Celestine’s family was involved in some illegal business, and when the truth came to the emperor, he decided to ban them from the Esclairk kingdom. Celestine's family secretly plotted against the emperor and forced Celestine to poison the emperor and empress. She did as told. After the emperor's tragic death, Athan Kingsley became the new emperor and vowed to avenge his brother's death. Two days later, the investigation pointed at Celestine's family, but they put all the blame on Celestine's shoulder, saying she did it for her greed for the empress’ position. Athan Kingsley killed his wife and later married his childhood friend, the main heroine of the novel. Cherry was not weak like the real Celestine, and since she got another chance in life, she was determined to change her tragic fate. Cherry decides to make her family pay before they frame her for the emperor's death. She started pretending to be mentally ill to appear as harmless as possible and got married. Unlike the original story, Athan Kingsley suddenly started paying attention to her mentally ill wife. On the other hand, Celestine began plotting against her family in the disguise of a crazy princess. Everything was fixed until a system appeared before her. "Welcome to The Accidental Ruler novel.
