[A gentle, virtuous young lady from a prominent family VS a modern woman who transmigrated]
Sang Yunshu and her younger sister were twins, but from childhood their parents treated them unequally, favoring the younger sister simply because she was lively, outspoken, and entertaining.
Unlike her sister, Sang Yunshu was dull and old-fashioned, always following the rules.
In her previous life, her younger sister stole her identity and married the powerful young marshal of the Jiang family, only to meet a tragic end.
Sang Yunshu married the son of the merchant Gu family. They were a loving couple who lived happily ever after, becoming the talk of the town.
Unexpectedly, both sisters were reborn.
In this life, her younger sister steals her good match and stubbornly insists on marrying into the Gu family.
Sang Yunshu readily agrees. She has no idea the Gu family is a den of vipers, a cesspool that devours people, and that the Gu family's young master is no suitable match either.
Having lived again, Sang Yunshu only wants to live freely and happily for herself. She wants neither the Gu family's young master nor the Jiang family's young marshal.
But what is she supposed to do when the Jiang young marshal, once notorious for his womanizing, suddenly changes his ways and clings to her day and night, insisting they spend their lives together?
Sang Yunshu puts on a magnanimous smile and says,
"My parents said that, to continue the Jiang family line, you should take plenty of concubines."
Jiang Shaoqing pounces on her, his voice full of tender affection:
"Shu'er, please, let me be yours, all right?"
In the end, even though she and her sister end up on different paths, Sang Yunshu still comes out a winner in life.
