The writer of this novel is a brazilian youtuber called "Zy" that was exposed a few months ago for exchanging nude pictures with an underage girl that was one of his subscribers. She was around 15.
I like the idea of bigger chapters, even if there is a smaller quantity of chapters released. But, at the same time you should keep an eye on the flow of your story. It isnât worth disrupting the flow the story to change the chapter sizes.
