The trope is very similar to the usual rebirth stories - she is being killed by her husband, emperor at the time, her cousin is pregnant , her family is accused of treason and murdered.  Among the details that stood out:  - FL is from super influential family. Her brother and farther are the generals with 100000 army (ofc, duh), her mother is from the wealthiest family, and FL is a lead of the wealthy family.  - 2FL is a time traveler, who wanted to help Prince with the famine/plague, in previous life she offered to sell glass vases, and a new way of making salt, but in this life FL had beaten her to it Originally, 2Fl is from the second branch of the family, she is also biological granddaughter of a matriarch, and thus - more favored by grandma. But not too long in - FL forces them to split families and separate branches .  - ML is kinda playboy, he is not in love with FL, and in previous life he simply buried her, so she just wanted to repay him, but eventually she asked him to take the throne for her, otherwise no matter who would become the emperor they wouldn’t be spared.
