So what if she's my sister-in-law? You seduced me first.

[Time travel & brother stealing brother's wife & superior bowing down & later fighting and vying & both are virgins]
A royal decree for marriage forces Ning Yu, who has traveled through time, to marry Chong Xi, the heir of the Xie family, whose fate is unknown on the battlefield.
When news of the crown prince's death in battle reached her, she went to a temple to pray for her deceased husband in order to find some peace and quiet, but instead encountered a lecherous man.
Good heavens, this lecherous man eats her food, drinks her drinks, and even sleeps in her bed, while constantly threatening her life with a knife.
Ning Yu endured it all to survive, but she never expected that the "lecher" she hated so much was actually her brother-in-law.
Everyone in the capital says that Xie Erlang is a kind and gentle man, but only Ning Yu knows that he is a ruthless and cruel person with a kind and gentle exterior.
He humiliated his widowed sister-in-law, sold official positions, plotted rebellion, and framed and spyed on his colleagues. During the time she was kept by him at his villa, she witnessed him commit countless atrocities.
In the first year of Jianwu, the old emperor passed away, and the Xie family raised an army in rebellion. Ning Yu finally found a chance to escape the clutches of men.
However, in September of the same year, in a small courtyard in the southwest, Ning Yu, who was six months pregnant, was surrounded by a large army.
She saw a man in a black and gold dragon robe slowly emerge from the crowd, looking at her with a sinister smile. "You toyed with my feelings, used me like a dog, Ning Yu. Do you know how much I've missed you these past six months, how much I've wanted to kill you?"
