Main campus learns about Karma's cliff jump assassination too. Since the main campus doesn't know about Koro-sensei, they think that Karma is suicidal because of some major parental issues And proceed to make some more assumptions about how he is only aggressive because it's his way of asking for help.
This leads some forceful bonding between Karma and some of the other students who want to help him. Both classes swarm Karma with positive affection, which gets E-class extremely protective of Karma when around main campus students

Summary
"Okay," Kayano slams her hands on her desk. "Anyone notice Class A acting weird?"
"YES!" Maehara yells. "Thank god it's not just me. They're acting so weird."
"Yeeeees," Okano groans. "Like what."
The class agrees with nods and bewildered looks because Class A has been acting..... Odd. Unusual.
"Heh," Karma scoffs. "It's not just the A Class."
3-E freezes.
"Wha...?" Isogai starts, eyes wide.
"Haven't you noticed? It's not just the A Class. It's the whole main campus," Karma says. "Class A, B, C, D, the senpais, even the senseis. They're all acting the same."
"No," Nakamura whispers, horrified.
"Yep," Karma pops his lips to the sound of the last letter.
Okajima thumps his head on his desk.
~~~~~~~
Nobody expects to see Asano standing in front of them. His face is troubled.
"Shit," Yoshida breathes. "You too?"
Asano's eyebrows raise up.
"They're acting similar regarding you, also?"
"Fuck," Itona deadpans.
~~~~~~~
Or, the fic where everyone can't stop loving and doting on 3-E and Asano, and they suffer in embarrassment and shock.

Kunugigaoka, Karushuu Has An Announcement: Karma Is Not Pregnant. Stop Saying He Is. by VanillaMintTea

Summary
Alright, Karma thinks. He's done with the small talk. He's done building up to the point. Obviously Shuu's not getting it.
"Apparently, according to Kunugigaoka, I'm pregnant," Karma deadpans.
Gakushuu does an incredible spit take with his coffee, very similar to those of characters on TV. It makes Karma want to grab a bowl of popcorn and sit back and watch.
"You're WHAT?"
~~~~~~~
For some reason, Kunugigaoka assumes Karma is expecting Gakushuu's kid.
Why? Who the fuck knows. Karma and Gakushuu surely don't.
Why does everyone assume that? Just because Karma is a hermaphrodite, doesn't mean he's pregnant. Also, they're not that irresponsible!
Why is no one listening? Karma isn't pregnant!
