Fortunately and pitifully, Li Lu was reborn into the past. I gained something I never had before, but also lost a lot. Not every protagonist is willing to be reborn and go back to the past, because there are too many uncertainties. When Li Lu returned to the past, she wanted to take good care of her mother and sister and let them live a good life. This was not difficult. Li Lu also wanted to find Chen Guan and be with him as before, which was difficult.
There are many rebirth articles on the Internet. Most people who have read rebirth articles have fantasized about being reborn, going back to the past, and changing the current unsatisfactory or regretful situation. Li Lu is the same, even more eager. When Li Lu is halfway through her fantasy, she can no longer fantasize. She is reborn, changes the things she wants to change, and inadvertently changes the things she doesn't want to change - meeting that Chen Guan.
