I'm not sure specifically as I haven't read it in detail. But typically, there would be a protagonist who is likely at the center of the story, facing the challenges of the loveless world.
Maybe there is an antagonist, not necessarily in the traditional sense of being 'evil', but someone or something that represents the aspects of the loveless world that the protagonist has to overcome. It could be a system, a group of people, or an idea that stands in the way of the protagonist's search for a more loving or meaningful existence.
No, it's not a true story. It's likely a fictional creation.
One main theme could be the struggle against a cold and unfeeling society. The protagonist might be constantly facing the apathy of the world around them.
Since I don't know which specific 'loveless novel' you're referring to, I can't say for sure who the main characters are.
Without having read the 'loveless graphic novel', it's hard to say for certain. However, it's common for there to be a central character who is facing some sort of emotional turmoil related to love or lack thereof. There could also be characters that represent different aspects of love, such as a jaded ex - lover or an idealistic new acquaintance, all of which interact with the main character and drive the story forward.
The phoenix is the central figure no doubt. There could be a group of antagonists, such as a council of dark mages who see the phoenix as a threat to their power. On the other hand, there may be a wise old sage who guides the phoenix, even if only from a distance. There might also be ordinary people in the story who are affected by the conflict between the phoenix and the world, and their reactions and interactions with the phoenix can also be important parts of the story.
Not having read the book, it's difficult to name the exact main characters. However, if the title is any indication, Pheonix is likely the central figure. There could be antagonists who represent the 'world' that Pheonix is against. And perhaps there are other characters, such as a sidekick or a wise elder, who help Pheonix in their struggle. For example, there could be a character who provides Pheonix with valuable information or a special weapon to fight against the world's challenges.
Since I haven't read it, I can only guess. There must be the princess herself. There could also be a prince who might be either an ally or a rival. And perhaps a wise old mentor who guides the princess through her difficulties.
In 'the princess against the world novel', the main character is of course the princess. There might be her loyal servants or friends who play important roles. Maybe there's an old wise mentor figure who guides her in her fight against the world. And on the other side, there could be those who oppose her, such as the leaders of other kingdoms or some dark creatures from a forgotten realm.
Mat Cauthon is an important figure. He is Rand's friend, with a roguish charm and a mysterious connection to a dagger that brings him both trouble and power. Egwene al'Vere is also crucial. She is a strong - willed woman who begins to learn magic and has her own journey of growth and discovery in the story.
I'm not sure specifically as I haven't read this exact 'home and the world novel'. But usually, there would be a protagonist who serves as the main lens through which we view the relationship between home and the world. This character might be someone who is caught between the two, trying to navigate their place in both.
