I really like the fanfic about Bagheera and Shere Khan. It often shows a different side of their relationship compared to the original story. In some fanfics, they might have to team up against a common enemy, which is quite interesting.
The 'bagheera love story' could potentially be about Bagheera's love for the jungle and its inhabitants in a very platonic and protective way. Since Bagheera is often portrayed as a wise and solitary character, it might be a story that shows his softer side when he develops an affection for something or someone in the jungle. For example, he might have a special bond with Mowgli that could be seen as a form of love in the sense of loyalty and care.
In the Jungle Book Mowgli story, Mowgli's main adventures include his struggle against the evil Shere Khan. Shere Khan wants to kill Mowgli because he is a human. Mowgli, with the help of his animal friends, tries to outwit the tiger. He also has adventures in learning the jungle's secrets. He learns how to climb trees like a monkey, swim like a fish in the jungle rivers, and hunt small prey. His relationships with the other jungle animals, whether friendly like with Bagheera and Baloo or hostile like with Shere Khan, form the core of his adventures.
Yes, 'The Jungle Book' which features Mowgli has some elements based on real - life in India. Rudyard Kipling, the author, was inspired by the jungles of India and the various animals and cultures there. Mowgli, the boy raised by wolves, represents a fictionalized version of the relationship between humans and nature in that context.
