Well, a free story might offer unique perspectives. Since it's free, the author may not be restricted by commercial demands and can fully explore their ideas. It could introduce us to new characters and settings that are quite different from mainstream stories. For example, it could be set in a fictional world with its own rules and cultures, and the characters could have extraordinary abilities or personalities.
A free story could be a great source of entertainment. It might have unexpected twists and turns. Sometimes, free stories are written by amateur writers who are just starting out, so it could also be a platform for new talent to showcase their work. This means we might discover some really fresh and interesting writing styles that we haven't seen before.
