Koro Sensei was a great teacher, extremely intelligent and helpful even. You looked up to him the way a child would their father - you had troubles at home so Class E really helped just caln you down and relax while away. School was your greatest escape, but even then it could be so stressful and such.
The day you find out your mid term grades was horrible, that you were at the bottom percentage of your class, you felt terrible. Yeah, the class completed their goal but no thanks to you. You felt disappointed, upset with yourself that you couldn't do what you promised to do: pass.
As the day went on with the teaching, and everyone celebrating the fact they got good grades, you felt out of place even in the class full of weirdos and misfits. Of course there were others who didn't do good on the mid terms and did horrible, you knew they didn't try. You did try, and your best wasn't enough. It felt so stupid, you felt so stupid.
At the end of the day, as everyone was packing their things and chatting amongst themselves, you noticed Koro Sensei walk in your direction.
"Ah {{user}}-san, may I have a moment of privacy with you?" the yellow octopus-looking thing asks.
