Is there a romance novel with a modern female protagonist traveling back to ancient times that you can recommend?

The female protagonist traveled from the modern era to the ancient era and was saved by a rich family. This family was very good and mainly consisted of a master and two young ladies. The old man was a good man, so he wasn't very good at making money. The female lead was very smart, so she helped them run the business in order to repay their kindness (the female lead had always been dressed as a male). The male lead seemed to have quite a status. He was a prince or a lord.
The first time the male lead and female lead met was when the male lead and two of his men passed by the female lead's backyard in a carriage. They saw a peach tree and wanted to pluck it to quench their thirst. They happened to meet the female lead and the two of them had a verbal battle. In the end, she was stumped by spending money to buy peaches (the female lead was actually quite shrewd). He couldn't remember what happened after that. It seemed that one of the two sisters of the female lead and the brother of the male lead had a crush on each other. The female lead set him up to see her sleeping with her sister in order to test him. The brother was furious when he saw the female lead sleeping with the person he liked. In the end, he found out that the female lead was a woman and immediately went to redeem himself. In the end, of course, they got together.
There seemed to be a plot in which a woman who liked the male protagonist set up a trap for the male protagonist to drink wine with aphrodisiac and lock the male protagonist and the female protagonist together (the female protagonist was still dressed as a male at that time). The female protagonist made a small sacrifice and did not lose her virginity. Then, when she saw that the male lead was fine the next day, she was very shocked. At that time, it seemed that the female lead was sleeping on the male lead's lap. After that, she believed that the male lead was Gay. That woman's name seemed to have the word 'Lou' in it. The female protagonist seemed to often sleep with the male protagonist. She thought that the male protagonist did not know that she was a woman, but in fact, the male protagonist had long known.
That's about it. I can't remember the name because it's been a long time. I hope those who have read this book can provide some clues. Thank you.

"I recommend Ah Xing." It's an ancient romance novel. It tells the story of a young lady from a wealthy family who transmigrated to a poor family in ancient times and how she changed her and her family's lives. The book was updated at least once a day. The plot was moving and very attractive. I hope you like this fairy's recommendation. Muah ~😗
