Nalu was NOT a favorite ship of mine AT FIRST. Now it is. At first I didn't like it because of Lucy's "Comedic" abuse of Natsu. I always preferred to ship Natsu with a nicer and more kinder and relatable character and thus I started writing Natsu X Reader. But now nalu is a ship I can get behind more than any other but I still love the freedom of writing a Natsu X Reader story.
Nalu over Nali any day though if that's what your asking.
