Can you recommend an ancient novel where the female protagonist comes from another time and space while the male protagonist is a bastard son who is treated as a useless person?

The female protagonist should have transmigrated here. The male protagonist was a concubine's son. After his father died, the mistress wanted to chase him away. In the first few chapters, the male and female protagonists got married. The male protagonist asked the female protagonist if she wanted to leave or follow him. Later, the female protagonist left with him. The female protagonist did not know how to wash clothes and cook. When the male protagonist saw it, he tried to find a servant for her. Later, when the male protagonist was a teacher, there was a student's sister who was interested in him. Then the female protagonist was jealous. He couldn't think clearly about anything else. Comrades, help me think of a name.
They should have been kicked out on the second day of their marriage, and then the student's sister should have sent him eggs. Or clothes that he had made himself. It seems that I stayed at their house for a while (I don't know if it's because I've watched it for a long time and now I want to watch it again)

Answer 1

The female lead transmigrated and became the concubine's daughter of the Marquis's Mansion. Her status was low, but she was engaged to Prince Leng's son. However, her in-laws did not like her son and did not love her. In the end, she could only be the concubine's daughter after the engagement was broken off. The plot is similar to the one mentioned in the question. I hope you like my recommendation.
