Unconventional Qing Dynasty Transmigration
She is the legitimate eldest daughter of an Earl, with a birth mother and an elder brother to support her, so she doesn't have to worry about anyone fighting her at home.
It is said that given her family's standing, her wedding coronet will be adorned with Eastern Pearls, so there's no need for her to scheme to marry a respectable husband.
Once married, as a legitimate wife, an daughter-in-law personally chosen by her father-in-law and groomed to be the future mistress of the household, others should be grateful if she doesn't cause them trouble.
If you think this means she'll be idle, then you're wrong! Because... she has to contend with all sorts of men, including, but not limited to: her husband's father, her husband, her husband's brothers, and her husband's subordinates. If she doesn't win, her entire family will be doomed.
...Which transmigration deity's brain short-circuited to arrange this?!
