Around 2010, I read an adventure novel. The main characters were some students, and there was a fat man.

Not having read the 'Fat Man and Little Boy Novel', if it follows the historical narrative, there could be characters representing the ordinary people affected by the development and dropping of the bombs. People in Hiroshima and Nagasaki who had their lives completely changed. These could be among the main characters as the novel might show the human side of this historical catastrophe.

Since we don't know the details of the 'fat man carnival story', it's hard to say for sure. But most likely the fat man himself is a main character. There could also be carnival workers, like the ticket seller, the ride operators or the food vendors who might be important characters in the story.

Obviously, the fat man is one of the main characters. But there might also be other characters who interact with him, like those who judge him or those who are his friends (if he has any in the story).

I'm not entirely sure who all the main characters are without reading the book. However, it's likely that there are characters related to the historical settings in which the fat man is placed. These could be people from different social classes, like a nobleman who looks down on the fat man, or a poor beggar who has an unexpected encounter with him. There might also be family members or acquaintances of the fat man that are central to some of the stories, perhaps showing different sides of his personality or how he is perceived within his own social circle.

The full text of Being Fat can be found in document [6].

Since I don't know the exact 'the fat man story', I can't say for sure. But surely the fat man is one of the main characters. There might also be his friends, family members, or people he interacts with in the story.

😋I recommend the following novels to you: 1. [Demon Blade: The story of a fat man who was discriminated against in the tribe and was sent to the Eagle Wing Army. He finally showed his strength.] 2. "The Krypton Player": The story of a fat man who lost weight due to a wrong transmigration experience and obtained the Krypton System. 3. [Supreme Martial Overlord: The story of a fat man whose soul was embedded in a new body, how he rose against the heavens and became a Martial God.] 4. "Sword Slaying the Wilderness": The story of a 340-pound fatty who had been awakened by a vast amount of martial arts knowledge and combat experience, and turned into a sword saint. I hope you like this fairy's recommendation. Muah ~😗

Definitely 'The Adventures of Tom Sawyer' by Mark Twain. Tom Sawyer's adventures in a small town along the Mississippi River are full of fun and excitement. He gets into all kinds of scrapes, from whitewashing the fence in a clever way to getting lost in a cave. It's a great read for students who love adventure and also gives insights into life in a different era.

😋I recommend "Loving You Is Ordinary Warmth". This modern romance novel tells the story of Shen Wenqing and He Siyu adopting four children, including a high school student. I hope you like this fairy's recommendation. Muah ~😗
