Well, from the title 'kono naka ni hitori imouto ga iru light novel', it could potentially be a story centered around a male protagonist who has a sister. Maybe it's about their daily lives together, the challenges they face, or some kind of mystery or adventure that they get involved in because of their relationship. Light novels usually have elements of slice - of - life, fantasy, or drama, so this one could be a mix of those.
I'm not entirely sure as I haven't played this visual novel specifically. But generally, a visual novel with a title like this might be about a story where there is a sister figure in a particular situation within the narrative world of the game.
Well, from the title 'kanojo ni uwaki sareteita ore ga web novel', it could potentially be a story about a male protagonist ('ore') who has experienced his girlfriend ('kanojo') having an affair ('uwaki').

It might also explore the relationship dynamics before and after the affair within the context of a web - based novel.

Since 'kou 2' isn't a common term that I'm familiar with, it's hard to be precise. However, if we break it down, 'time leaped' implies a time - travel aspect. So perhaps the novel is about the protagonist ('ore') who has made a time leap into a situation or place named 'kou 2', and the story could revolve around how he deals with this new environment, the changes in the timeline, and the consequences of his time - leap.
I'm not aware of its popularity. There are so many web novels out there, and without more information or research, it's hard to say if it's popular or not.
Given that we have so little information about 'kou 2 ni time leaped shita ore ga novel', it's a challenge to recommend similar works. But if we consider the time - travel aspect, novels like 'All You Need Is Kill' (which has a time - loop aspect similar to time - leap in a way) could be considered. Also, in the world of Japanese literature, there are often stories that play with time and space concepts. So perhaps some works by Haruki Murakami, like 'Kafka on the Shore' which has a certain dreamy and time - warped feel to it, might have some loose similarities in terms of exploring different states of existence which could be related to the idea of time - leaping in the given novel.
I'm not sure specifically as I haven't read it. But generally, a light novel often contains elements like unique characters, a fictional world, and an interesting story. It might be about a relationship or an adventure related to 'black yome' with a polite 'yoroshiku' aspect in it.
As I'm not acquainted with this particular light novel, we can only make assumptions. The 'black yome' might be the main character, and there could be supporting characters like a sidekick who helps 'black yome' in their adventures or a love interest. There could also be an antagonist who opposes 'black yome' and creates conflict in the story. Without reading the novel, it's difficult to be more precise about the main characters.
