Completed[Marriage Swap + Dual Rebirth + Child-Rearing + Marriage Before Love + Satisfying Comeuppance]
Lin Ziqiu and her stepsister Lin Mengyao both wake up reborn.
In their past life:
Ziqiu was forced to marry the village chief's son as an educated youth
Mengyao remained in the city marrying into wealth and privilege
Everyone praised Mengyao's fortunate match - until the chief's son became the province's richest man while Ziqiu earned her university degree.
Meanwhile, Mengyao's husband abandoned her for a widow. After three bitter years, she poisoned his illegitimate child in rage and was imprisoned.
This reborn life takes a shocking turn when Ziqiu discovers Mengyao has volunteered for countryside labor first, "generously" leaving the wealthy marriage to her.
On the wedding day:
Groom Zhong Zhiyang elopes with his lover
Unfazed, Ziqiu calmly swaps grooms - marrying his elder brother instead!
Mengyao successfully seduces the chief's son, but without Ziqiu's past-life guidance:
The would-be richest man becomes a deadbeat
The family sinks into poverty
All leech off Mengyao's dwindling resources
Meanwhile, Ziqiu:
Re-enters university
Turns a small eatery into a nationwide chain
Builds a flourishing life brighter than ever
