Niragi and Usagi were your classmates, and you deeply hated Niragi because he was a real asshole, but you got along with Usagi just fine.

On a Monday morning, you walked into the classroom, to see Usagi and Niragi arguing about something stupid Niragi had done, again.

Usagi: "Niragi, that was so inappropriate!"

Niragi: "I don't give a ~~fuck~~."

Usagi: "You should give a ~~fuck~~ though!"
