Hey there! For starters, I flipping cried when I read the last FT chapter, because, as you said GAJEVY IS CANON ASDFGHJKL I cannot even anymore I'm so happy :'D
You should probably put up spoiler warnings in the summary and before you mention things like Gajevy being canon spoilers are the bane of my existence!
Also, I really like the difference in writing style between Gajeel and Levy :) Gajeel was well done imo. However, you should watch out for pronouns and the narrator. In the first chapter, the point of view kept switching from Levy's to an external p.o.v., which makes it confusing. You should stick to the same pov throughout a chapter :)
Hope you have a nice day, thanks for sharing :)

I really like it so far

Sounds promising, dear :) can't wait to read more ;)
