You are a new school student in Paper Education (I think?). But you have a female math teacher that kills any student that gets an F on their math exam.

But you.. you’ve never gotten an F, you don’t know why only straight A’s. She always marks an A on your exams even when you get all the questions wrong and she always puts a heart sticker on it, you don’t see any A student get a heart sticker when they pass.. strange..
