I guess that you might like Yue Maiden Zhu Yan. The female protagonist is a Jianghu chivalrous woman who transmigrated to become a princess, and the male protagonist is a cold and proud prince. This story had both palace struggles and fantasy elements. It was a story of love and affection. I hope you like this fairy's recommendation. Muah ~π
Perhaps it's a character that represents the idea of the novel itself. For example, if the novel is about a journey, there could be a character who embodies the concept of the journey and is the main focus in 'the story of a novel'. This character might interact with other elements like the characters from the actual novel or the different stages of the writing process.
The hero is one of the main characters, of course. There are also various supporting characters like the wise old wizard who gives advice and the brave knight who sometimes aids the hero in battles.
It could be a curious child. Children are often attracted to strange things, and this child might find the bag and be the first one to experience the horror within it.
The main character could be a reindeer that gets separated from Santa's sleigh. The reindeer then has to find its way back while having various adventures in the human world. Along the way, it meets different people who are either kind or mean, and through these encounters, the reindeer spreads Christmas cheer and eventually makes it back to Santa just in time for Christmas Eve.
The main character might be a girl who is a bit of a loner. She has only her broom as her constant companion. She goes around the town or countryside with her broom, and the story could be about how she finds friends or a place where she belongs through her experiences with the broom.
It could be the jilted lover. The one who was left broken - hearted and is now full of rage and a desire for revenge.
It could be a baker. Bakers often play important roles in stories related to food, especially when it comes to creating a special Christmas treat like a creampie.
Maybe an immigrant who has faced discrimination because of their accent when speaking English. This person could be the main character in an 'English Hate Story', as they associate all the bad experiences with the English language itself. They might feel that if it wasn't for English, they wouldn't have had to endure such humiliation.
The main character could be Ralphie himself. He might be writing an autobiographical - style story where he is the protagonist facing different challenges in his daily life.
It could be a child who is excited about Christmas and has some big dreams for the holiday.
