The Husband Who Left His Father And Left His Son Actually Wants Me As His Concubine

Lu Jinshi had Kefu's order spread throughout the city, and when he saw that he was almost twenty, no one dared to marry him.
After being ridiculed as an old girl, Lu Jinshi had a bold idea. He would choose a handsome young scholar from his academy to borrow seed and have a son, leaving the father to keep the son.
Lu Jinshi chose Rong Yi, a young scholar with an unparalleled handsome appearance. As he wished, he and Rong Yi became a loving couple and gave birth to a son.
Before Lu Jinshi had time to get rid of his child's advantageous father, he received the news that his grandfather was seriously ill and had to return to Chang'an to see his grandfather, Marquis Yongxing, on his last journey.
Rong Yi also said that one of his elders was running out of time and he had to rush back to Chang'an to see him off.
So Lu Jinshi and Rong Yi went to Chang'an City together.
Just arrived in Chang'an, after Lu Jinshi had rested.
Rong Yi said that he would take her to visit the Rong family's parents tomorrow and give her a status.
When Lu Jinshi was thinking about whether to give Rong Yi a title, he heard that Rong Yi had given her a title to be his concubine...
Rong Yi: "Jin'er, my father has promised me another marriage. I can only take you as my concubine. For the sake of giving birth to my eldest son, I will allow you to be my side..."
Lu Jinshi didn't wait for Rong Yi to finish, and had Rong Yi kicked out of the house.
He is simply rebelling against Tiangang. Rong Yi, who left his father and left his son behind, dares to make herself his concubine?
It wasn't until the Queen Mother's birthday banquet...
Lu Jinshi saw the seventh prince who was praised by his stepsister that there was no one in heaven and no one in the world...
It was then that he was shocked to realize that she had borrowed the seed to the son of the Tian family!
