"No need to seem like that, I know. I was very late at that, but thankfully, our country has rules that prevent elementary students from repeating a class. If they cannot learn something, it's the responsibility of the school."
These laws were introduced after King Epsilon took power. He wanted schools to take responsibility for the education of the children.
In the past, they didn't care at all. They just made students repeat the class over and over while using the same method.
With the new rules, they had no choice but to try their best to make sure every student was up to standard. Otherwise, their license could be taken away.
"I never knew that, but now that you say it, it's true I never heard of any repeat classes when I was in elementary. So your grandma decided on this method to make you able to read?"
"Yes, I bet she would laugh her stomach off if she knew I now became a librarian."
