The person who is telling the story is often called the narrator. It could be the main character in a first - person narrative, sharing their own experiences directly. For example, in 'The Catcher in the Rye', Holden Caulfield is the narrator, and we see the story unfold through his eyes.
We can learn about the events that are taking place in the story. The narrator will describe what is happening, who is involved, and where it is all going on.
Well, it's hard to say exactly. Different editions of the novel might have different attributions. You could try checking the copyright page or looking for reviews that mention the author.
In the manga, it's not straightforward to identify a single father figure. There are multiple characters who could potentially play that role depending on your interpretation.
