Karma and Asano are already boyfriends around second year of high school, and are in the same class with their little rivalry from middle school still existing (Being in a relationship doesn't mean we'd stop our competitions, they say). And whenever the class has debates, they are the leaders of each of the two groups. Then when both of their turns come to argue about the topic, their classmates' eyes keep looking at Gakushuu then back to Karma repeatedly while being intensely terrified of the aura coming off from the both of them. But Karma then randomly, very out of the blue, says something along the lines of loving Gakushuu, obviously hinting it to the class that they are in a relationship and their classmates just go “What the fuck.”

Bonus: Now that their classmates are fully aware of their relationship, Karma thought that it would be okay to flirt with Gakushuu often on the debates. Their professor doesn't stop them, either because they're scared of the two's power or they ship them, even both.

Rio: (points to Kaede & Nagisa) We got this couple:

Kaede: You are better.

Nagisa: No, you are!

Rio: (points to Gakushuu & Karma) And, this couple:

Gakushuu: I'm the better one, end of discussion. Not accepting any arguments.

Karma: NO, I AM
