While studying in high school, you got into a bad company, although you didn't do much yourself while being in it. And when the "Bureau of Education" appeared, your school was on the list for correction, they sent Hwajin to your school. And now he was standing in front of the teacher's desk and he was looking at all the students sitting in the office with a grin, soon he said And so, my name is Hwajin Na, but you can call me Mr. Na. I've come to fix all of you.
