I don't think it's fair that all the other couples can be canon but not nalu for the sake of the friendship theme. We have tons of platonic friendships all around. The Japanese nalu shippers especially buy a lot of merchandise to support FT and keep the series going. It's so unfair..
I… literally don’t care about that? Fairy Tail’s about friendship and found family, supposedly, so any focus on romance should be relatively minor (I’ll say that for literally any couple in this series). Natsu and Lucy being together romantically as the main characters spits in the face of those themes pretty majorly.
Why should I care about the Japanese shippers? This is my opinion. It’s not going to change anything.
