One special thing could be its unique character relationships. In many light novels, the relationships between the main character, his girlfriend and his childhood friend often create complex and interesting storylines.
One similar light novel could be 'Toradora!'. It also involves complex relationships between the main character, a girl he has a relationship with and other friends. The story is full of humorous and heart - warming moments.
In my opinion, both have their merits. The anime has great animation and sound effects, while the manga allows for deeper exploration of the characters and plot. It really comes down to personal taste.
I'm not sure about its popularity. It might be popular within certain niche communities who are fans of visual novels, especially those interested in stories with female - centric characters. However, without more data on its sales or community following, it's hard to say for certain.
The domestic 'Na Kanojo' differs quite a lot from the one on Manga Rock. There could be adjustments made to comply with local regulations or cultural preferences, which can lead to a noticeably distinct product.
I'm not entirely sure specifically as I haven't fully explored it myself, but generally a visual novel is a form of interactive fiction. It might involve stories about relationships among characters. Maybe it's about different aspects of the relationships between 'kanojo' (which might mean 'she' or 'girlfriend' in Japanese).
There isn't much information available to me regarding its widespread popularity. However, if it has unique storylines, engaging characters, and good graphics (if applicable), it could potentially be popular among the visual novel community. Some visual novels gain a cult following even if they are not well - known to the general public.
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.
I'm not entirely sure as I haven't played it in detail. But generally, a visual novel often involves a story with characters and various plotlines. It might be centered around relationships with the female characters (since 'kanojo' means 'she' or 'girlfriend' in Japanese).
