Comments of chapter undefined of Attack on Titan: Mutant System

if nothing in life is free and I understand that you want to get something out of this but you also have to understand that you are using characters from other authors for your story, if it were a story where it is originally yours and not a fanfic that is something else you could charge what you want for it but with fanfics at least look at the method of the other authors on this platform in how they publish their fanfics since they always say that if you want to go 20 chapters ahead of the story they are reading they can pay since they are releasing free chapters as time goes by to keep people interested, they don't publish the first 20 chapters and then you say they have to pay to see more and then go publishing chapters where the only content is that you say pay to read them this causes that one loses interest since from my point of view one reads fanfics to kill time and distract oneself not to spend money on works that use characters from other series/man ga/novels/books/movies among others.
