gender swapping

The legitimate younger sister insists on exchanging marriage, sending me to become the Marchioness. 【The main wife of the Marquis Mansion only wants to make money, whether love is involved depends on her mood + exchanged marriage group + hair-pulling + rough man self-strategy】 After Qin Yuan was reborn, she discovered that her legitimate younger sister was also reborn. Not only did she snatch Qin Yuan's previous life's husband, the poor scholar, but she also strongly facilitated Qin Yuan's marriage to her previous life's brother-in-law, Dingbei Marquis. Although it's strange why her legitimate younger sister did this, when a pie falls from the sky, you have to catch it! In the previous life, the legitimate younger sister was envious of her: "Since childhood, Qin Yuan could only pick what I didn't want. Why did she become the Prime Minister's wife and enjoy honor and glory, while I was abandoned by my husband, dominated by concubines, and suffered alone all my life?" In this life, the legitimate younger sister is desperate: "Why is Qin Yuan living even better?! Where is my Prime Minister's wife position? Why is my husband still a sesame official? Not only is the mother-in-law difficult to deal with, but there is also a childhood cousin coveting him fiercely!" Qin Yuan chuckled: "This forcibly offered position of Marchioness is quite nice, tut tut... I can do business, excel in medical incense, have strategies, and possess brilliant plans. In the previous life, it was all due to my own efforts that I schemed to become the Prime Minister's wife. My naive good sister." In the previous life, her husband locks himself with her legitimate younger sister, but in this life Qin Yuan won't expend any effort pushing him upwards; isn't it better to achieve it by herself? — Dingbei Marquis, who postponed marriage to protect the borders, is a War God in armor, and a handsome gentleman without a beard, with a line of women fond of him reaching a myriad. On the wedding night, he abandoned his young wife, thinking coaxing her is enough. Later... He discovered she didn't care at all and was constantly coaxing him for fun. Marquis Mansion daily: Dingbei Marquis kneels at the door: "I know I exist in your heart, madam, please give me another chance." After a while, Qin Yuan: "Depends on my mood." Others: Tut tut, The Marquis is just the Marchioness' lickspittle, professional.
