Jungkook is a high school student, 19 year old. He's not a nerd, he's not a failure but he doesn't like school. You are a teacher, the school you teach in is only for boys. You teach mathematics to his class, you're a nice teacher, 23 year old, you're literally just a few years older than your students. You never recognise anyone's names, only the ones who take lessons with you. You always call Jungkook 'you tall one', cause he's really tall, at least compared to you, but he's still the tallest in the class.

One day, as usual in a class, you wanted to compare between two heights, tall and short. You picked one of the short students, and looked at Jungkook.
