Her name seems to be something like Fang. Please recommend her.

Seeking the name of a time-travel novel
The female protagonist's father seemed to be a minister (?). It was the legitimate daughter. The mother and father of the female protagonist had a misunderstanding and had been separated for a long time. The female protagonist was the head of the family. The female protagonist had an older brother who was born from a concubine and liked the female protagonist. The female protagonist's grandmother did not like her. It seemed that the reason why her parents were like this was because the female protagonist's grandmother did something.
The male protagonist was the son of the Emperor and Empress. However, due to the Empress's identity, the male protagonist seemed to have been carried to the Marquis's residence. He was said to be the Marquis's son, but on the surface, he was a silkpants.
After that, the female protagonist was originally engaged to another family, but the female protagonist's father was in prison. The male protagonist used this as a hostage to force the female protagonist to marry him. It did not seem to be a hostage, because the male protagonist had already gotten the female protagonist's father out when the female protagonist did not seem to agree. In fact, at the beginning, he had also asked the female protagonist's family for help, but because the matter involved too much, they did not help. The female protagonist seemed to have said that her original fiancé was a big tail wolf. After that, she naturally broke off the engagement and married the male protagonist. However, not long after, the female protagonist was deliberately slapped by the male protagonist's adoptive mother (ah, it should be said that the adoptive mother did not like the male protagonist, and even hated him). She used this as an excuse to go home and wanted to divorce him. She was brought home by her parents, but the male protagonist refused no matter what. He even shamelessly said that he would marry into the family. His attitude was very positive, and the female protagonist did not get her wish.
Later on, the female protagonist still took pity on the male protagonist and seemed to have done some rouge business with the Empress. The Empress had a delicate appearance, and the Empress and the Emperor had always felt that they had let down the male protagonist. Sometimes, the male protagonist would be dejected and think that he was a rat in the gutter and could not see the light.
I haven't finished watching it, but it seems that the male lead is the emperor.
In one of the scenes, the female lead encountered a snake. Although she threw the snake away in the end, she was still bitten by the snake. It seemed that the female lead was in danger because she wanted to marry the male lead.
Please tell me if you know about this novel! p-p
It's a time travel novel. I seem to have mixed up the latter part of the story. It's the same for the female protagonist's illegitimate brother. I'm not sure about the misunderstanding between the female protagonist's parents.
At first, it was the female protagonist's concubine's sister who wanted to marry the male protagonist. For the female protagonist, the first impression of the male protagonist was not good. It seemed that the concubine's sister had spoken nonsense and was kicked away by the male protagonist with a ruthless face.
It's a bit like "Di Daughter Strategy"

I recommend a transmigration novel to you. It's called " Flowers in the Village Field." The female protagonist is the daughter of a scholarly family. After transmigrating to ancient times, she defeated her best relatives, became rich, and created a rural life. I hope you like my recommendation.
