I'm not entirely sure as I haven't read this specific light novel. It could be about various things like a complex relationship where the characters have some sort of uncomfortable or strange interactions as 'iya na kao sare nagara' might imply something like 'while being made to show an unpleasant face'. But this is just speculation without more context.
I'm sorry, but I don't have any information about the main characters in this light novel. Without reading it or having more details, it's impossible to say who the main characters might be.

E Kao's book referred to Harry Potter and the Sorcerer's Stone, which was written by K Rowling.

One major difference is the medium. Manga is a visual medium with panels and illustrations that can directly show the story's events and characters' appearances. A light novel, on the other hand, is mainly text - based, relying on the reader's imagination more for the visual aspects. For example, in Domestic na Kanojo, the manga can vividly depict the complex relationships between the characters through detailed drawings of their expressions and body language. In the light novel, these relationships are described in words, which might allow for a deeper exploration of the characters' inner thoughts.
As someone who loves reading novels, I have no way of knowing if E Kao is still writing novels. E Kao was a well-known online novel. His works were mainly about humor, suspense, science fiction, and other topics, which were loved by many readers. If you are interested in E Kao's works, you can search for his works on major literary platforms to read.
One common theme could be magic and its use. Since 'Charmed' is about witches, fanfics might explore different magical abilities or spells. Another theme could be family bonds, as the Halliwell sisters in 'Charmed' have a strong family connection. And perhaps the theme of good vs. evil, which is central to the show, might also be explored in these fanfics.
It could be the unique relationship between Benjamin and Elizabeth within the context of the 'Charmed' universe that makes it special. Their interactions might bring a fresh perspective to the story.
