By that I mean it has a mood similar to the show (not overly comedic and focuses on the characters first and foremost). I also think his way of writing the Shinij and Asuka pairing was incredibly true to the characters as they were in the show. Its a painful, bloody, tearful process and slow to develop. Its not some instant WAFF fest that disregards the past or mental traumas, and even after they finally become a couple, they stay in character, they don't shrug off their flaws and "heal through the power of love".
Basically, a fic that is an extension of the show, believably so and without the unfortunate additions found in many fanfictions (self-insert, tons of new pilots, wacky plots, Shinji getting a core/becoming more than human,crossovers, etc. You know what i'm talking about).
Any recommendations?
Sorry for any weird grammar/spelling issues, as its late and...yeah.
