Substitute matriarch wants a divorce and to run away VS noble, powerful official and former top dog learns to bow his head

-

In her previous life, Su Ningzhao gave her heart to the wrong man. She spent her entire dowry and used all her connections to pave the way for the impoverished scholar Gu Changyan's imperial exams and official career.

Gu Changyan happened to learn that the Minister's household had once wanted Su Ningzhao to take her twin sister Su Ningyue's place and marry Xiao Ci. She had stubbornly refused, and Su Ningyue had eventually died of grief.

What he didn't know was that Gu Changyan had always loved Su Ningyue. When they were young, she gave him a few pastries and a little money, and he became utterly obsessed with her. He disregarded Su Ningzhao's years of sacrifice and support, leaving her to die miserably amid endless humiliation and torment.

They are both reborn. This time, Gu Changyan breaks off the engagement first, determined to marry no one but Su Ningyue. With no other choice, Su Ningzhao switches the marriage and marries her brother-in-law, taking her sister's place as the matriarch of the Xiao household.

As the Empress Dowager's own nephew and the emperor's trusted confidant, Xiao Ci wields the power of the Embroidered Uniform Guard. He is the ideal husband every noble young woman in the capital dreams of. Even his public announcement that he already has a son and daughter cannot deter the great clans from seeking an alliance through marriage.

Su Ningzhao struggles at every turn in the Xiao household, pitting her wits against two mischievous children and Xiao Ci's seemingly innocent sworn sister. She dares not let her guard down for a moment.

Xiao Ci discovers the secret behind the switched marriage but keeps it to himself. As they grow closer, he falls in love with her and spoils Su Ningzhao rotten...
