Perhaps in the fanfiction, Naruto loves the moon because it reminds him of someone he lost. The moon could be a symbol of peace and unity for him, similar to his dreams for the ninja world.

If there are tensions between different pure - blood families or groups, their marriage could be seen as a strategic move to strengthen alliances.
