I am not sure which book you are referring to. However, if you are asking about the plot of a certain novel, I can provide you with some relevant information. Generally speaking, it was common for the female protagonist to faint and reminisce about her childhood with the male protagonist in novels. It could strengthen the emotional connection between the male and female protagonists and provide background for their relationship. As for whether the female protagonist was the male protagonist's butler or driver, it depended on the plot and setting of the novel. In some novels, this female character might become the male protagonist's family assistant and play an important role in taking care of the male protagonist. In other novels, this female character might be the male protagonist's butler or driver and have some kind of intimate relationship with the male protagonist. I need more specific information to answer your question.
