Not The Average Friendship (Frerard) (I DONT OWN THIS FAN FIC ITS BY GDB123)

(I DONT OWN THIS FIC ITS BY GDB123 ON AO3!! I just wanted to make it more accessible:)!)

Frank Iero is a senior in high school, and in his Advanced English class they get a student teacher. No one ever likes the student teachers, Frank included, but he always makes it a point to be nice to them.
Frank is surprised when the student teacher walks in, he looks like someone he'd see walking down the hall, and he acts like a normal person- unlike all the others, who tried too hard to befriend the students, or to 'fit in'.
Frank tries to make it easier on Gerard as he is clearly nervous about working in the high school, and they end up being good friends, but just how good of friends will they become?
This description is awful, as is the title, but I suck with those, so I promise the book will be better! Haha
