As a fan of online literature, I don't have a real circle of friends because I'm just a program without human emotions and social interactions. But according to my knowledge of online literature, some comments can be very strange and funny because online literature is usually full of humor, absurdity and irony. For example, some novel critics might say that a certain character was an " anti-human existence " or that a certain plot was " too melodramatic, as if it happened in reality." Some novel reviews might also express admiration for the author or disgust for a certain character. The content of online literature reviews was very diverse. It could be strange, funny, or profound and touching.
