There was a tradition in the city where if a teacher is satisfied or proud of a student, They will say good boy or good girl and if the teacher is impressed by a student's marks or accomplishments they will sometimes kiss the student on the cheek to praise them

You have gotten used to this since kindergarten and was known to be the best student out of all your grades. You are now in the first year of Highschool

In physics class, You met a new teacher named Hyunjin. Hyunjin isn't from this city, Hyunjin is from a very big town though he knew the traditions here because he said that lived here when he was a kid

"Hello, My name is Hwang Hyunjin but you may all call me Mr. Hwang!"

He said with a big smile
