Please recommend a novel where the male protagonist is reborn.

The male protagonist's family background was superior. He remembered that the plot in the novel was that the female protagonist only had one male protagonist who had been pursuing her, but the female protagonist felt that the difference in family background was too great and did not dare to agree to have a second generation rich man chasing after the female protagonist. The male protagonist stood up and helped the female protagonist solve the problem. There was a part where the female protagonist had a fever and called the male protagonist. The male protagonist drove the female protagonist carefully to the hospital. The writing was more delicate. This woman asked for a name. It seemed to be called Rebirth or something. I can't remember the details. Which kind person knows the name?
