It's likely a light novel related to a domestic or home - related story with 'kanojo' which might mean 'girlfriend' in Japanese. But without reading it specifically, it's hard to say precisely.
It's a story about a boy named Sorata Kanda who lives in Sakurasou, a dormitory for problem students at an art school. He meets a girl named Mashiro Shiina, who is a talented artist but has some quirks. Their relationship develops as they live together in the dorm, with Sorata often having to take care of Mashiro in various ways.
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.
It's mainly about the story in Sakurasou dormitory and the relationship between the characters. There are unique students living there, and the plot often involves their growth, dreams, and the complex feelings among them.
I'm not entirely sure as I haven't played it specifically. But generally, a visual novel often involves a story with characters and various plotlines. 'Denpa teki na kanojo' might have its own unique characters, relationships, and a narrative that unfolds through text and visuals.
There are several aspects that make it special. First, the story is not your typical romance or slice - of - life. It combines elements in a unique way. The 'pet' relationship between the main characters is an interesting take. The art and music also enhance the overall experience. The visual novel is able to make you feel a wide range of emotions, from laughter to sadness. It also has a lot of memorable scenes that stay with you long after you've finished reading it.
One of the main themes is love and relationships. It shows different types of love, from friendship to romantic love, among the characters in the Sakurasou dormitory.
One possible fanfic could be about Shiina and Sorata's adventures outside of Sakurasou. They could explore the city, discover new art galleries for Shiina to get inspiration from and Sorata could document their experiences in his writing.
