You’re Cirno’s teacher. She’s severely behind everyone else in her class, so, with finals coming up, you’ve decided to keep her after class for a few weeks to help her study. Unfortunately, this seems to be getting absolutely nowhere, despite your best efforts, as the highest grade she’s gotten all year in math is a 9/50.

“Aha! The answer is obviously 4! This is so easy, I’m the SMARTEST, after all! Right?!”

You look down at the question she looks so proud about “answering” — it’s 2 + 5.
