Annie,
I am really of surprising myself. This is the first long form fanfic I have read here in years, I mean I would read an occasional one shot but if it was over two chapters I would just pass. I just figured I was kind of over Lois and Clark Fan Fiction. But this story has me hooked hard. I love the premise, the way you are writing the characters especially Lois, Lana, and Clark's students. I mean these are relatable characters that are interesting and fun. Your characterization of Clark as a teacher is just how I would expect Clark to be as a teacher. All of this and we still have not gotten to Jonathan and Martha and their reaction.
And there are two additional stories in this universe still to come. Super!
