He died. Can you recommend a similar novel?

There was a novel.
The female protagonist's surname was Xiao. Before her rebirth, she was a concubine. When she gave birth to a child, she was killed by her wife. After her rebirth, in order not to become a concubine, she chose to be a guard in the residence.
The male protagonist was originally surnamed Shen, the Di son of the Prime Minister (actually raised for the Emperor), but later changed back to his mother's surname.

Answer 1

The one I recommend to you is 'It's Hard for a Concubine'. The female protagonist was surnamed Xiao. Her predecessor was a woman who was killed by a mistress. After her rebirth, she became a concubine. In this role, she took every step carefully and worked hard to survive. In the process, they would also discover that sheep were not necessarily slaughtered, but could also be wolves. If you're interested, you can take a look. I hope you like this fairy's recommendation.
