After flirting with the aloof prince, the concubine ran away pregnant.

[The superior bows down + a melodramatic runaway with a child + a wife-chasing nightmare]
Afu died suddenly and transmigrated into the body of the lowest-ranking maid in the Marquis's mansion.
She was determined to save money to redeem herself, but was instead betrothed to the prince Xie Xun as a concubine.
A concubine is nothing more than a plaything for the master to vent his lust. Once the mistress enters the household, she will be sold off at best, and at worst lose her life. She is not as well off as an ordinary maid.
After Xie Xun got engaged, everyone said that his fiancée was no pushover. Before she even reached marriageable age, she had personally dealt with several of her father's concubines, some of whom died and others were crippled.
Once she entered the house, Afu's good days were over.
Afu knew this day would come eventually.
However, I overheard Xie Xun say to the Lady of the Marquis, "She's just a concubine. If the Princess Consort finds her an eyesore, she can deal with her herself after she enters the household."
Afu still felt as if she had fallen into an ice cellar.
She managed to obtain the indenture from the Lady of the Marquis and prepared to leave.
The usually aloof and noble young master was unwilling to let her go, saying, "I'm giving you a child to rely on, so don't cause any trouble."
Without a word, he stopped giving her the contraceptive and confined her to a side room.
On the eve of her wedding, Afu, three months pregnant, faked her death.
Several years later, Xie Xun took up his post as Protector-General of Liangzhou and stopped at a tea shop along the way.
He stared at a miniature version of himself and chuckled softly.
"...Afu, you're really daring."
Behind the curtain, the hand kneading the tea paused.
