It could be that there are multiple main characters. Maybe there are friends or family members of the main couple who also play significant roles. For example, a best friend who gives advice on the relationship or a family member who opposes the love due to some reasons, like differences in social status or family history.
There might also be a character who serves as an antagonist in the love story. This person could be someone who is also in love with one of the main characters and tries to break them apart, or someone who has a different view on how love should be and tries to impose it on the main characters.
The main theme could be love. In many novels, love is a central element. It might explore different aspects of love, like the intensity of it (the 'all or nothing' aspect), and how love is designed or shaped within the context of the story.
I'm not sure as I haven't read the novel specifically. But usually in a novel with such a title, there could be a couple who are facing hardships together. Maybe one of them is a strong - willed person who is determined to hold on to love despite the odds.
I'm not sure as I haven't read the novel. But usually, in a novel with a title like this, there would be characters who are in search of love or who are learning the true meaning of love. It could be a couple, perhaps a man and a woman who have to overcome many obstacles in their relationship.
Well, without reading the novel, it's hard to say for sure. However, the title seems to suggest that the main character is someone who desires a love from a particular man in a way that is not random but designed. So there's this main person who has this strong craving. And the 'him' in the title is clearly an important character too. There could also be other characters like a matchmaker - type figure if the 'by design' part involves someone or something arranging the love. Maybe there are rivals or past loves that come into play as well to create conflict in the story.
Often in a novel titled 'All for Love', there would be at least one character who is the protagonist in the love story. There could also be secondary characters like friends or family members who either support or oppose the relationship. For instance, a best friend who gives advice to the main character in love or a family member who tries to break the relationship due to some family interests.
I'm not sure as I haven't read the novel. But typically, the main characters would be the ones most closely associated with the central theme of love. It could be a couple in love or a person who is on a journey to find love.
I'm not sure as I haven't read the novel specifically. But usually in a novel about love, there could be a protagonist who experiences the belated love, perhaps a male character, and then there might be the object of his love, like a female character.
I don't know as I haven't read this novel. There could be a solitary figure, like a lone wanderer in the night.
Since the title mentions a duchess, she is likely to be one of the main characters. There might also be a male lead who is in love with the duchess.
I'm not sure specifically as I haven't read it. But it could have a protagonist who is a detective or an investigator trying to figure out the deaths related to the design.
