The witch is a central figure. Her beloved could be someone she has known for a long time, like a childhood friend. This would add a sense of history and depth to their relationship. There might also be antagonists in the story, such as other witches who envy her love or humans who are afraid of their relationship. These characters would create conflict and drive the story forward.
It could be about the power of love. The witch's love for her beloved might be so strong that it endures till the end. It may explore how her love overcomes various obstacles and difficulties.
Since I haven't read it, I can't say for sure. But it's likely that the witch and her beloved are the main characters.
Another possible antagonist could be a rival in love. There might be someone else who also desires the witch's beloved and would go to great lengths to break up their relationship. This character could create a lot of drama and tension in the story by plotting against the witch and trying to win over her beloved.
Perhaps it's about a witch who has made a vow or has a natural inclination to love someone deeply and unconditionally until her last day. It could also be about the sacrifices she makes for this love, or how the society in the story's setting reacts to this relationship between a witch and her beloved.
The main theme might be undying love. Since the witch is said to love her beloved until her dying day, it could explore the depth and permanence of love, perhaps in the face of various obstacles and challenges.
Without having read the book, it's difficult to determine the exact main characters. But it's likely that there will be at least two main characters involved in the love relationship. There could be a character who is hesitant about love and another who is trying to make the relationship work. There might also be side characters such as a wise old person who gives advice on love, or a rival who adds tension to the relationship.
The main characters would likely be the woman who is pregnant and about to be married. Her fiancé, who rejects her, is another key character. Additionally, there could be a best friend or a mother figure in the story. The best friend might be there to support her through the difficult time, while the mother figure could either be a source of strength or part of the problem depending on the plot. For example, if the mother is against the marriage because of the pregnancy, that could add more complexity to the story.
The main characters could be the witch herself and a human. The human might be a curious adventurer who stumbles upon the witch's lair and they start to fall in love.
I don't know as I haven't read the novel.
I'm not sure specifically as I haven't played it. But usually in a love - themed visual novel, there would be a male and a female lead.
