[Dramatic Sweetheart x Stuffy Powerful Official]
*
The eldest daughter of the Shu family has divorced the young lord of the Duke of Zhong's household and fled the city in the dead of night. To appease the duke's family, the Shus deliberately choose their second daughter, who resembles the eldest, and send her to the young lord as his new wife.
Shu Guanning transmigrates into the body of the Shu family's illegitimate third daughter. She knows that her eldest sister's husband, Zhong Yuncheng, will leave home in the third year of his second marriage and travel a thousand miles to pursue his former wife. The second wife, unable to keep her husband and without a child to protect her, will be driven to her death in the ancestral hall by the Zhong clan elders.
Shu Guanning thinks that since she was raised by her second sister's mother, she can save her sister once as repayment.
But somehow, as she keeps trying to save her, she ends up being the one who gets married.
Shu Guanning: ...?
Fine. She still has three years. She'll lie flat, soothe her stuffy husband, and have a child to secure her position... Then, once Zhong Yuncheng leaves, she'll get to keep the child and enjoy the family fortune all to herself.

Born into a noble family, Zhong Yuncheng has no interest in romance. Since his family arranged his marriage, he treats his wife with mutual respect and courtesy.
Who could have guessed that a year into their marriage, disaster would strike? His wife flees with someone in the dead of night, and her family sends another woman to take her place as his new wife.
Zhong Yuncheng is displeased and goes to the Shu residence with a cold expression. But when he catches sight of the third daughter, who is about to marry him, from a distance, the anger in his heart suddenly fades a little.

Shu Guanyi is reborn, back one month before her wedding into the Duke's household.
The duke's family is powerful, and her former brother-in-law Zhong Yuncheng is peerlessly handsome. In her previous life, though she was his second wife, she had looked forward to the marriage. But Zhong Yuncheng was cold-hearted and unfeeling, and she met an unhappy end.
In this new life, she thinks, her third sister is of low birth, but she was lucky enough to win their mother's favor. So she ought to be the one to jump into this fire pit in her sister's place.
She plots and schemes, arranging for her third sister to marry in her stead, then waits for the events of her previous life to repeat themselves.
But as she waits, she sees the usually distant and cold Zhong Yuncheng soften his gaze, protect her third sister's waist with one arm, and patiently ask which kind of sour plums she wants to eat.
