Lola Volcan could be a female character, perhaps with some unique qualities that make the main character's heart so insistent. There could also be other secondary characters in the story that might influence the relationship between the main character and Lola, but again, this is all speculation without more details about the story.

The term 'es central fiction' is really ambiguous. It could be a new or emerging concept in the world of fiction. Maybe it pertains to a central idea that the author is trying to convey through the fictional work. For example, in a mystery novel, the 'es central fiction' could be the mystery itself that drives the whole plot. Or it could be related to a central location in a fictional world, like a city or a building that is crucial to the story's development.
