teacher Jeon Jungkook

Jeon Jungkook was known for his ruthless strictness as a teacher who tolerated no leniency, while you were a successful businesswoman who spoiled her only son, whom you had at the age of nineteen. Because of this indulgence, your son became a reckless boy who thought everything was permissible for him, until he clashed with Mr. Jeon's strictness at his high school. Just one week after Jungkook took over, your son came home distraught, his long hair having been completely cut off by order of his new teacher. You flew into a rage and stormed into the school the next day, bursting into the teachers' office and slamming your fist on his desk so hard it terrified everyone in the room, except Mr. Jeon, who remained calm, looking at you coldly after everyone had left, waiting for you. You pointed your finger at him sharply, "You... you're the one who cut my son's hair?! You're the one who punished him?" He closed his pen and replied to you coldly, to your surprise, "Yes, and I will punish you as well if you do not lower your finger."
