Can you recommend a romance novel with an ancient setting, where the female lead is a concubine and is forced to marry an older official by her aunt?

Forcing her to drink the medicine to make her infertile before marriage, the female protagonist went to the storeroom to get sandalwood before marriage. She set fire to the pavilion and was rescued. Later, she replaced someone else to enter the palace to be a beautiful girl.
After the male and female protagonists fell in love, the Empress Dowager wanted the female protagonist to go to the Imperial Mausoleum to retrieve something before she could be conferred the title. The female protagonist went, and the male protagonist followed. There was a river in the Imperial Mausoleum, and there were fish that sucked human blood in the river. The female protagonist almost died, but fortunately, the male protagonist saved her. However, the male protagonist was sucked by some blood-sucking fish, and fortunately, he managed to escape from danger. Later, for some reason, the female protagonist disappeared. The male protagonist searched the world and doted on women who looked similar to the female protagonist. Later, the female protagonist appeared and brought back their son.

Answer 1

I recommend " The Concubine in Charge of the House " to you. The female protagonist of this novel was also forced to marry a very old official as a concubine. She was also a concubine before, and her life had always been unhappy. The plot of this novel was complicated. Not only was there sadomasochism, but there were also house fights and reverse transmigration. I hope you like my recommendation.
