Qin Huiyin transmigrates into a book.
Her mother is a beautiful widow who's married three times, the village belle.
When her mother marries for the second time, Qin Huiyin gets a villainous stepbrother.
When her mother marries for the third time, the male lead becomes her stepbrother, along with a stepsister and stepbrother who are doomed to die young as cannon fodder.
Her mother, destined to be cannon fodder, keeps bouncing around in front of the villain and the male lead every day, unaware that the two of them have already planned hundreds of ways for her to die. To survive, Qin Huiyin decides she has to cling to the male lead's coattails and the villain's too. Cover both bases, and maybe she'll manage to latch onto one powerful supporter.
The trouble is, both the grassroots villain and the grassroots male lead are so hard to raise. Bringing them up is practically killing her.
Later, looking at the plump, healthy villain, male lead, and the stepsister and stepbrother who were originally destined to die young, Qin Huiyin decides it's time to retire after a job well done, hiding her achievements and leaving no trace.
As the richest woman in the land, she wants to find a handsome young man to marry into her household and live happily ever after. But...
Every matchmaker in the capital shuts their doors to her.
Damn it! She'll throw money at them. She has to throw money at them.
But then, one night, someone slips into her room, opens his clothes, and asks, "Is it not enough for just me to marry into your household?"
