My Cousin Forced Me To Change My Marriage, And I Agreed. Why Are You Crying?

[Rebirth + Space + Marriage first, love later + Double cleanliness + slap in the face]
As soon as Su Yunwan opened her eyes, she was reborn before she got married, and unlocked the jade pendant space in advance.
Reborn with her was her cousin Su Shuangshuang.
In her previous life, she was married to Li Zian, a scholar who had been married since childhood, while Su Shuangshuang was married to He Xiangbei, an Orion in the village.
A few years later, Li Zian went to high school and became the long-lost son of the Pingyang Marquis Mansion. He was worshiped as the Grand Secretary of Agriculture of Xia Hua Kingdom. Su Yunwan was also named a first-class imperial concubine and enjoyed glory and wealth in the capital.
But Su Shuangshuang's fate was extremely bumpy. Not long after she got married, He Xiang went hunting in the mountains and broke his leg. From then on, he became a disabled person and lived in poverty.
Su Shuangshuang seized the opportunity of a heavy job and pretended to fall into the river and was rescued by Li Zian. Naturally, the marriage exchange was successful and she waited for her husband to earn her life.
As a result, Su Yunwan's life was still prosperous, but Su Shuangshuang's fate was worse than in her previous life...
