In the original story, Harry often uses magic in combat. But in this fanfiction, as a pacifist, he would avoid such violent magic use.

Well, the original Harry Potter story focuses on themes like friendship, courage, and the fight against evil. However, 'harry potter is a submissive veela fanfiction' seems to focus more on different power dynamics and a unique relationship.

And the Veela addition changes the magical landscape and the social interactions within the story completely, which is a huge deviation from the source material.
