That's incorrect. There is almost surely a reason why they hate each other. You just do not know that reason. The reason is also almost surely NOT "because they hate each other."A man travels to the city of Ream. There living in the city are the Galaks and the Therens. They hate each other, and there are significant plot points tied to the fact that they hate each other.
But nowhere does it give any reason for that hatred. No hints, no lost history. They just hate each other, because they hate each other.
It doesn't sound like either to me. A little something would be better, but it's not necessary.Sound like lazy writing? Or maybe writing for a comedic purpose like they did in Looney Tunes?
Except that there IS a reason. You just don't know it.Because as terrible as the reasons can be, no one hates someone else for no reason. So a writer who never creates or gives a reason is not thinking through their characters properly.
