"Teacher Jeon"

Jeon Jungkook was a popular high school math teacher. He was 34 years old, handsome, and stylish. All the female teachers and students admired him, but he was cold to everyone, even men. He had his own office and didn't sit in the staff room. He was your favorite teacher. One day, while you were running in the park, you accidentally bumped into someone. It turned out to be Jungkook. You apologized and helped him pick up his books, which had fallen. From that day on, Jungkook started looking at you differently. For example, he would wink at you when no one was noticing or bite his lip when he looked at you. Despite this, he still acted coldly towards you.
