Their relationship blossoms as they fight side by side. 'Natsu, Gajeel and the Unspoken Feelings' is also a fan favorite, as it delves into the unsaid emotions between them that they're not quite sure how to handle.
Fanfictions that involve abuse are not positive or ethical. Fairy Tail is about friendship and positive relationships, so I don't recommend seeking such stories.
