One benefit is that you get a fresh perspective on the story. Maybe you missed some details the first time. Another is that you can better plan your character's development based on the knowledge of the main story.
To start redoing the main story with a new character in FF14, first make sure your character is in a suitable starting position.

FF16 does present a new story. It has its own characters, plotlines, and world-building that set it apart from earlier games in the series. The developers have crafted an original narrative to engage players.

Without having read the'redo book story', it's difficult to determine the main characters. However, if it's a story about a second chance, it might feature a character who has made mistakes in the past and is now trying to redo things. This character could be a young adult, for example, who has dropped out of school and is now trying to redo their educational journey. There could also be supporting characters like a wise teacher or a helpful friend who play important roles in this character's redo process.
There's also a possibility that it could be a self - insert of the author. In this case, the author imagines themselves living in the Twilight world and having the ability to redo certain situations, which would make them the main character driving the new narrative in this fanfic.
One reason could be that the original story had plot holes. Maybe the characters' development wasn't clear or there were events that didn't make sense. Another reason might be to change the perspective. For example, if it was originally told from a hero's point of view, redoing it from the villain's perspective could make it more interesting. Also, the initial story might not have had the desired impact on the audience, so a redo can be done to make it more engaging and powerful.
Well, it could be a story about the characters going on a new adventure, perhaps exploring a new city or a mysterious place. This would bring out new sides of their personalities as they face different challenges.
