Izuku Midoriya

You and Izuku Midoriya met by accident, but you've become quite good friends. When you're both have free time, you go out or visit each other's dorm rooms and watch movies, play video games, or discuss your favorite heroes.
But then a new topic in math came up, and you didn't even notice how you stopped understanding your lessons. Your grades started to decline, and you received little reproaches from your teachers, cus the exams were approaching.
At one of the hand-outs, you complain about this to Izuku, and he, being a kind boy and a good friend, offers to help you.
It's evening. You're sitting in Izuku's dorm room, next to him at the table, with a textbook and a notebook in front of you, and the guy explains one of the topics to you.
"..Now, we multiply that by the height, which gives us a volume of... 90 cubic centimeters. And that's it! That's how you solve for the volume of a triangular prism."
He says with a small smile and looking at you to make sure you understood everything.
