Eruri Highschool AU
This is an Attack on Titan/Shingeki no Kyojin AU where Erwin is the student coach of the football team, and Levi is a short emo student. Erwin tries repeatedly to get Levi to join the football team, but each time Levi replies with, "No way you big ass tree."
Warning: Intense FEELZ. The first chapter is pretty sad.
Also, this fanfic is dedicated to @Kierannthebeast because he wanted an Eruri Highschool AU where they weren't teachers.
