One day, Mr.Mukoyama was asked by an educational trainee after the class that the trainee showed.
The trainee said to Mr.Mukoyama "Please tell me something about my class lesson."
The answer that Mr.Mukoyama gave him was below.
"I would like to tell you just one thing."
The point is that he said "I would like to tell you just one thing" and then he "recalled the class lesson".
