One

Well, they saved the world, now what?
Nagisa and Karma are good friends, but Nagisa has developed feelings for Karma that go well beyond friendship. He's afraid Karma will hate him if he finds out, but he doesn't know that Karma is dealing with the same thing.
The two of them deal with everyday life in E class now that Korosensai is gone. Life goes back to normal, except now there are feelings to navigate.
(I do not own Assassination Classroom or it's characters. If you don't like same love, don't read it. First try at a fanfic in a long time, so don't be a dick.)
