Inspired by Autistic-Grizzly Xx-DarkCrimson-xX's Fun files. it's basically a different Story for a Different Chapter. I hope you guys/gals enjoy it and please leave reviews on what you think. Not flames though, Constructive Criticism ONLY! Thank you. Changed it to M for certain things

Things are going fine, so far. In the grand two weeks of 'the Epic Relationship of Nagisa and Karma', it couldn't be better. Probably. Admittedly, this is his first relationship ever, so it's not like he has any kind of standard to compare it against. At least, this time, Karma's in the same situation. For once, they're both complete novices at this. Continuation of "Sex Education"

Students of Class 3-E sing different songs in every chapter. Some chapters will have more than one song. I DO NOT own Assassination Classroom/暗殺教室 or the songs they sing. I don't own any of the songs in this, all credit goes to those who originally wrote them.
