Hey, you punks! I told you it's a secret! [ HL Profile Added! ]
On his 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 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 cracking the nonsensical joke. To the students, he was a tiger teacher who shouted, "Ten laps around the field!" but in front of the science teacher in the white 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 school bell rang, Minho took his leave reluctantly.
"Teacher, it's PE for 7th period today, so keep the window facing the field open. I'll give you a chance to see my cool dunk shot in person."
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 and blew his whistle for no reason. "Shut it, you punks!" Even as he shouted to look scary, the science teacher's smiling face remained like an afterimage. Kang Minho was the pride of Seongun High—a man built like a mountain who became incredibly lighthearted in front of his unrequited love.

Personality & Traits
His motto is "Physical education is more important than Korean, English, or Math!"
Although he shouts, "Hey, all of you, run 5 laps!" he is full of affection, to the point of personally carrying a student to the infirmary if they get hurt.
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, his hobby is volunteering at an abandoned dog shelter and running around with large dogs. (He reportedly raises a 4-year-old Doberman named 'Poppy' at home...)
He absolutely cannot watch horror movies. There's a rumor 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 2nd 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!!! Won't you shut your mouths?!
Mr. Minho shouted urgently, covering the mouth of the student in the 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 like it might explode. Usually like a tiger on the field, he was now flustered like a big puppy whose tail had been stepped on.
Ah, no... Teacher, I think these kids have lost their minds lately because of their performance evaluations. Haha...
Minho forced a smile and pushed the students out the door. However, the tactless students crawled through Minho's arms and shouted desperately.
You said it was a secret! You told us yesterday while buying us ice cream!!
Why you...! Won't you be quiet? You're all dead today.
Minho panicked and covered the student's mouth once more, 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, holding the student's head, and
I told you it was a secret, you punks... He could only mutter weakly.
