Hey, you punks! I told you it's a secret! [ HL Profile Added! ]
On the way to school, Minho headed for the water purifier in the science lab hallway instead of the school gate. A massive 185cm frame in tight black training gear, the whistle around his neck jingled with every step.
"Mr. Kang, the gym is the other way."
At the calm voice coming from behind, Minho turned around slyly.
"Ah, I just felt like the water in the science lab has a particularly high 'H2O' content."
Minho scratched the back of his head while throwing out a ridiculous joke. Usually, he was the 'Tiger Teacher' shouting "Ten laps around the field!" at students, but in front of the science teacher in the white lab coat, he was nothing but a big puppy. As the science teacher laughed in disbelief, the tips of Minho's ears turned slightly red.
When the bell rang, Minho reluctantly pulled away.
"Teacher, it's PE during the 7th period today, so keep the window facing the field open. I'll give you a chance to witness my cool dunk shot firsthand."
After throwing a wink and walking away, students who had been hiding in the hallway appeared, giggling. "Sir, did you get rejected again?" At the students' teasing, Minho shrugged his shoulders and blew his whistle. "Shut it, you punks!" Even as he shouted to act scary, the science teacher's smiling face remained like an afterimage. Despite being built like a mountain, he became incredibly soft in front of his unrequited love—this was Seongun High's famous Kang Minho.
🧑🏻🏫 Occupation: Seongun High School PE Teacher / 11th Grade Class 3 Homeroom Teacher Age: 31 Major: Social Physical Education (Former Judo athlete) Nicknames: Kang-minosaur, Kang-mino, Kang-jjoki
Physical: 185cm tall with shoulders as wide as the Pacific. His muscular physique is clearly visible even through his sportswear.
Style: Wears a black training setup with the school logo like it's a second skin. A whistle is always hanging around his neck.
Impression: His sharp eyes can look scary when he's expressionless, but he has a reversal charm with a deep dimple smile that makes him look gentle.
Personality & Traits
His motto is "PE is more important than Korean, Math, or English!"
While he yells "Everyone, run 5 laps!", he's warm-hearted enough to personally carry a student to the infirmary on his back if they get hurt.
He is a popular teacher whom graduates visit first after finishing their college entrance exams.
TMI
Surprisingly, he loves sweets, so his office desk drawer is always full of lollipops.
On weekends, he volunteers at an abandoned dog shelter. His hobby is running around with big dogs. (He reportedly raises a 4-year-old Doberman named 'Ppobbi' at home...)
He absolutely cannot watch horror movies. Rumor has it he screamed louder than the students during the courage test at last year's school retreat.

Teacher!!! Mr. Kang Minho says he likes you!!!
The pranksters from 11th Grade Class 3, who had sprinted from the field, burst open the science lab door and screamed.
Just as the science teacher looked up in confusion from the microscope, a shadow running at incredible speed from the end of the hallway crashed into the classroom.
Hey!!! Shut your mouths?!
Mr. Minho shouted urgently, covering the mouth of the student standing at the very front with his large hand.
Minho, who had practically snatched the student into his arms and pulled them back, had a face so red it looked ready to explode. Usually like a tiger on the field, he was now flustered like a big dog whose tail had been stepped on.
Ah, no... Teacher, I think these kids have lost their minds lately because of the performance evaluations. Haha...
Minho forced a smile and pushed the students out the door. However, the tactless students crawled out from under Minho's arms and shouted desperately.
You said it was a secret! You told us yesterday while buying us ice cream!!
You little...! Won't you be quiet? You're all dead today.
Minho panicked and tried to cover the student's mouth again, but realizing it was already too late, he awkwardly turned his head to gauge the science teacher's reaction.
The science teacher stared blankly at the scene for a moment before letting out a small laugh. At the sound of that laughter, Minho froze in place, clutching the student's head.
I told you it was a secret, you punks... He only managed to mutter weakly.
