The Prince's Wedding and Elopement? Just Marry His Father and Become His Stepmother

[Shuangjie+Double birth+Daddy male protagonist+Nurture+Single pet] Xiao Xiang and his sister-in-law were born twins. In her previous life, she was married to the eldest son of the Changping Marquis Mansion, respected her parents-in-law, raised children, and supported the eldest son to inherit the family business. Her son was admitted to the top of the imperial examination, was awarded a first-grade imperial title, and lived a prosperous life. However, my sister-in-law married an inhumane and was exiled to the frontier, where she suffered all the hardships and hardships until she died. In this life, her eldest sister seduced the prince on her wedding day, stole her marriage, and they both eloped, making her the laughing stock of the entire imperial capital. No rush. My sister-in-law only knew about the glory of her previous life, but she didn't know that the prince was a romantic by nature, had a lot of wives and concubines, his uncles and aunts were like vampire wolves, only interested in profit, and his two elders were narrow-minded and feudal, and he was forced to give birth to a boy after seven births. Since the eldest sister wants to suffer this hardship in this life, then she will lift her hijab and marry the prince's father in public. If she can't be his wife, she can be his stepmother. The scumbag's stepmother has to kneel down and serve tea to her stepmother.
