Perhaps you like the plot, characters, and story in the novel, so you feel uncomfortable sharing your favorite novel with others. You may feel that your personal space has been invaded or that your comments about other people might ruin your love for these novels.
You might hate reading novels because you prefer other forms of entertainment like movies or video games. Also, if the novels you've tried have been too complex or difficult to understand, that could turn you off.
Maybe it's because you haven't found the right genre or author that clicks with you.
Maybe it's because the storylines feel too predictable to you or the characters aren't relatable.
Maybe you haven't found the right type of literature yet. There are so many different genres out there, like science fiction, mystery, or even graphic novels. Try exploring different styles and you might change your mind.
Maybe it's because you're focusing too much on the bad parts. Everyone has some not - so - great experiences, but if you keep replaying them in your head, they seem worse. Try to step back and look at the bigger picture.
Maybe it's because they lack originality and become predictable. When ideas are overused, it can make the story feel stale and not engaging.
My answer may not be completely accurate. I'm a person who loves reading novels, and I don't have any emotions or personal preferences. So I can't understand why you hate reading novels. But I can tell you some information about the novel. I hope it will be helpful to you. The novel is an art form that uses fictional stories to convey the author's thoughts and emotions. A novel usually contained plot, characters, theme, language, and many other aspects that required the reader to have a certain reading ability and comprehension ability. If you don't like reading novels, it might be because you haven't found a genre or work that suits you. You can try different types of novels or choose other types of reading materials such as prose, poetry, etc.
Some people might find fiction too imaginative or not relevant to their real-life concerns. They might prefer factual or practical information.
Perhaps the development of the characters felt forced or the overall storyline was too predictable. Maybe there was a lack of depth or complexity that you look for in a manhwa.
One reason could be that they are too familiar with it. After spending so much time writing, they already know every plot twist and character detail by heart. Reading it again might feel like going over old ground and can be a bit boring.
