The main character of the book,"Provoke", was the female lead, Lu Nanxuan, who faked her death and changed her name to Xia Yuxuan. I recommend reading this modern romance novel. The plot is bizarre and the characters are profound. I hope you like this fairy's recommendation. Muah ~😗
In Steinbeck's 'East of Eden', Cathy fakes her death. Cathy is a complex and often immoral character in the novel, and this act of faking her death is part of her devious nature and her attempts to manipulate those around her.
In " A Powerful Official's Family Has a Godly Doctor's Wife," the female protagonist was tricked into taking fake death medicine and later found out that the male protagonist was still alive.

Maybe he had some secret motives or was under some kind of threat. It's hard to say for sure without knowing more details of the story.
I recommend "Noble Family's Favorite Marriage: Wife, Stop Making Trouble." This modern romance novel about wealthy families fits the plot description you mentioned. In the three years that the female protagonist had been married, her husband had never touched her. The reason why the female protagonist had divorced was that her husband had given her sister a diamond ring to betroth her to another life. At the same time, the novel also described how the female protagonist finally got her way on the night before her divorce and ran away, causing the male protagonist to be furious.
