The main character would obviously be the person who is submitting to the best friend's dad. Then there's the best friend, who would play an important role in the story as the link between the main character and the dad. And of course, the best friend's dad, who could be a strict, kind, or mysterious figure depending on the plot.
In addition to the basic characters, there could be a mentor - like figure in the main character's life other than the best friend's dad. This person could influence the main character's actions and decisions regarding their situation with the best friend's dad. There could also be a rival of some sort, either for the main character's friendship with the best friend or for the attention of the best friend's dad, which would create more drama in the story.
Since I haven't read the novel specifically, I can only assume that the main characters would be the protagonist (the one who has some sort of relationship with her best friend's dad), her best friend, and of course, the best friend's dad.
Perhaps it involves the main character finding themselves in difficult situations where they have to submit to the authority or wisdom of the best friend's dad. For example, they might be in a financial or emotional crisis and the dad steps in to help, but in a way that makes the main character feel like they are submitting. It could also explore themes of family, friendship, and growing up.
The dad is a key main character. He might be the stable force in the family but with a complex backstory involving his best friend. The best friend himself would be an important character, with his own personality traits and motives. And then there is the protagonist, which could be the son or daughter. They are the ones who will drive the story forward as they explore the relationship between their dad and his best friend, and deal with their own feelings about it.
I'm not sure about the exact plot of this novel as it could be quite specific. But generally, it might involve complex relationships and some sort of emotional journey related to the main character's feelings towards her best friend's dad.
Since I haven't read it, I can only guess. Obviously, the dad and his best friend would be main characters. And probably the narrator who is telling the story about them.
Since I don't know the exact novel, it's hard to say for sure. But likely, the main character would be the person working for their dad's best friend. And of course, the dad and his best friend would also be important characters.
One possible theme could be forbidden love. Since it involves a relationship with the father of a best friend, it's likely to be a relationship that society might not approve of.
It depends on the genre of the free novels. In some family - drama or coming - of - age genres, it might be a bit more likely to appear as a theme. But overall, compared to themes like romance or self - discovery, it's not a very common one. There are just so many other more popular themes that authors usually explore in free novels.
Since I haven't read it, I can only guess. The main characters would probably be the girl, her father, and his best friend.
It could mean that the character in the novel is surrendering or yielding to the authority or will of their best friend's dad. Maybe in the story, there are certain situations like the main character has to submit to the dad's rules or decisions for some reasons, which could be related to family, friendship, or some sort of moral obligation.
