In the modern rebirth, the female protagonist helped the male protagonist. Before the rebirth, the male protagonist saved This is a fan of online novels about rebirth, wealthy families, and the relationship between male and female protagonists. Here is my answer: The male protagonist and the female protagonist were together since childhood. Later, they went to a wealthy family. The female protagonist had a younger brother. In the modern rebirth, the female protagonist helped the male protagonist. Before the rebirth, the male protagonist saved According to the plot of the novel, we can guess that the male and female lead had some special relationship before the modern rebirth. In her previous life, the female protagonist might have helped the male protagonist or the male protagonist might have saved the female protagonist before her rebirth. This plot could allow the readers to have a deeper understanding of the relationship between the male and female protagonists, and it could also lay the foundation for the development of the subsequent plot. After the rebirth, the male and female protagonists might meet again and trigger a series of plot developments. The male lead might pursue the female lead strongly, and the female lead might be moved by the male lead's sincerity and start to re-examine her feelings. However, during this process, the female protagonist's younger brother might also develop a good impression of the male protagonist, causing complicated family relationships.
