How can maths fiction books help in learning maths?
Maths fiction books can make abstract maths concepts more concrete. For example, in 'Flatland', the description of the 2D world helps in visualizing geometric shapes better. They also create interest. When reading about a character using maths to solve a problem in a story, like in 'The Number Devil', it makes maths seem less intimidating and more like an adventure.

Attending a class reunion and meeting an ex novel
It was a common plot setting in novels to meet an ex at a class reunion. For example, there was a novel in which the female protagonist, Chen Can, was pushed to her ex-boyfriend, Long Jing, at a class reunion. Chen Can lied that she was married and had children, while Long Jing said that she was still single. In fact, Chen Can was still unmarried at the age of 28 because her first love was too outstanding and she felt that she was not as good as her first love after many blind dates. It was Long Jing who broke up with him at that time. They met again many years later. Although Chen Can was still moved by him, he also held a grudge. There was also the novel " The Fever ". After breaking up for many years, Lu Wuke met her ex-boyfriend, Shen Yixi, at a class reunion. When they were in university, Shen Yixi had doted on Lu Wuke to the heavens, but he didn't even look at her at the class reunion. When they were playing games, Shen Yixi chose the truth, saying that there was no one he couldn't let go of. However, that night, when he was drunk, his behavior was different. In addition, in a novel, after the female lead attended a class reunion, she had more interactions with her ex in the workplace. The ex became her boss, and a series of entanglements occurred between the two. The class reunion scenes in these novels often became important plots that promoted the development of the story and showed the emotional entanglements of the characters.
