here come the one with Hakkai. I hope you will like it.
Mathematics
Hakkai loved to teach. Before Kanan was abduqued he was a very good teacher. But this path was cut for him when he had killed the thousand of yokai and become one of them. Who in their right mind would let a yokai teach their children ? And the yokai thought the same of a man who had killed a lot of tem. They would be worried if he taught them.
So Hakkai had abandonned his dream. Only to found out that he still can have a student. He was happy when Sanzo had agree for him to teach the young saru. And Goku was a good student. He loved Hakkai like a big brother and study with application. In every way Goku was the perfect pupil. Every except for one : the mathematics.
For every problem Hakkai give him, Goku's answer was always the same. It always was zéro ! And no matter how much Hakkai had tried to explain to him the importance of the maths, the young boy still keep to say that the right answer is zéro. And in a way Hakkai understand him.
It was when he was home that Hakkai let his laugh come out. He don't know what amused him the most. The fact that Sanzo was irritated by the boy answer, or the fact that the boy is right when he say that, in the end, he will eat the fruit. indeed, in the end, the right answer, no matter the question, would still be zéro. But hakkai would be damned if he stopped to try to teach the mathematics to the saru. there is really too much fun with it !
End
I have laugh me head off when I have read Goku's answer to the mathematics problem. So, this story had come from it. i hope you have liked too.
