I'm not sure which novel or storyline you're referring to because the name may refer to different characters or plots. If you can provide more information, I can try my best to answer your questions.
Well, if 'animal well story' is a proper name for a particular story, without more context it's hard to say. It might be a story that focuses on the good deeds done by humans to help animals. For example, a story about a sanctuary where injured animals are nursed back to health and are able to thrive again.
Yes, many animals have interesting stories. For example, the story of the loyal dog Hachiko. Hachiko waited for his owner at the train station every day for years, even after his owner passed away. This shows the deep bond that can exist between an animal and a human.
I'm not sure who Claude and Fanny specifically are in this context. They could be two ordinary people. Maybe they met at a coffee shop one sunny day. Claude accidentally spilled his coffee on Fanny's book. He apologized profusely and offered to buy her a new one. Fanny was initially a bit annoyed but then she saw how sincere Claude was. They started talking and found they had a lot in common, like their love for old movies and hiking. And from that accidental encounter, their love story began.
