I respectfully disagree. Going back to the subject of the thread, I think that a story will be interesting for the reader if the characters who experience these events, are happy or sad with them, and ultimately succeed or fail, have a treatment or approach that is somehow new to the reader. But I think the story always comes first, everything else comes later. At least I always ask myself first: what is happening, what is the fact?, and then, to whom?
Anyway, it's just different points of view yours and mine.
For example, Faulkner said, about his novel As I Lay Dying, that he began by imagining a group of people whom he then put in a dangerous situation. I mean, he started with the characters and then wondered what to do with them.
On the other side of the coin, Kurt Vonnegut first had the idea for the novel Slaughterhouse Five and then started thinking about the characters.
That is, both points of view are valid.
I prefer to work with the story first because it makes it easier for me to create the beginning, development and outcome. I like to think of the characters as fossils that I only get to know as I unearth them. So, since I already know the ending, I wonder what those characters have to do to get there. But, according to the story, I decide to show only the features that are most useful to develop a certain plot. However, that is my style of work. You have your own view of the matter and that's fine too.
