Sadly, I have no clue about the author of 'carlisle cares fanfic'. Fanfics are often created by a wide range of people, and this one could be the work of an amateur or an experienced fanfic writer in some small or large fan community.
Well, it depends. If the woman was a central figure or her death drives the story forward, many readers or viewers could care. Maybe they were attached to her personality or her role in the narrative.
The truth is, if you don't have a passion for the game, you likely won't be interested in its story. However, the story often provides background, character development, and a sense of purpose within the game world.
Xie Bi 'an and Fan Wujiu were the names of the Black and White Impermanences of the netherworld. They were the messengers responsible for catching lawless people in the netherworld.
I don't know who the author of this novel is. There could be many relatively unknown novels with such a title, and without more information, it's difficult to determine the author.
Some might care if the woman's death has a significant impact on the plot or characters. Maybe it triggers a series of events or changes the dynamics of the story.
