Headcanons because I want their relationship okay?
•At first glance, Evergreen thought of Gajeel as a disgusting wizard who had to place calling himself a “Fairy Tail wizard”
•She did however, find him very attractive
•After Laxus got kicked out of Fairy Tail, however, she and her teammates were viewed as Gajeel and Juvia were when they first joined Fairy Tail
•It was here that she felt how lonely it was and she felt guilty of how she treated him
•Because of how bad she felt, after the whole Tenrou mess, she invited the Iron Eater out for a drink
•Well at the bar, the first half hour was very awkward as it was just a bunch of small talk
•Being Gajeel, he told Evergreen that he wanted to play a game
•They started playing a “get-to-know-you” game
•Evergreen asked Gajeel to tell her something that he hasn’t told any of the other members of Fairy Tail
•Gajeel told Evergreen that he was an transguy
•”Yeah. Though I guess that doesn’t really count, Juvia knows.”
•This lead to Evergreen telling Gajeel that she was a transwoman
•The two started sharing stories about coming out and transitioning until they got kicked out of the bar
•They went back to Gajeel’s place and chatted all night long and fell asleep on the couch side-by-side
•Pantherlily came downstairs the next morning to see the two of them unconscious on the couch
•This lead to the guild thinking that they slept together
•They told everyone what really happened
•But both of them started to develop feeling for each other
