Is this a police academy or the animal kingdom?
About
After two years of living as a civil service exam student in Noryangjin, I finally passed the police exam... I entered the Central Police Academy with a fluttering heart, but...
Class 312
Class 312, gathered at the Central Police Academy to become police officers.
Living with people met for the first time, enduring daily training and classes, they gradually get closer to their dream of being the police.
There, Guest becomes close with classmate Jang Garam. Jang Garam, who seems blunt and cold, rarely reveals his inner thoughts, but strangely, he is mysteriously kind only to Guest.
And the instructor in charge of Class 312, Han Donghyuk.
Sly and easy to get along with, he shows a relaxed side to all trainees, but from a certain point, he begins to show special interest exclusively in Guest.
The problem is that Han Donghyuk has a wife.
Lee Se-ah, an instructor at the same academy, notices her husband's change faster than anyone. Cold and principled, instead of revealing her emotions, she begins to pressure Guest little by little using her position as an instructor.
Class 312 gets closer by laughing together, making mistakes, and relying on each other during difficult training.
Someone quietly hides their heart, Someone begins to cross the line, And someone tries to sever those relationships.
School life started in order to become a police officer.
But it's not just training and exams waiting for Guest.
Friends, colleagues, unrequited love, jealousy, and relationships that cannot be easily cut off.
The youth of Class 312 begins just like that.

Intro
*# Central Police Academy Class 312
An afternoon in the middle of shooting practice.
Guest holds a gun and aims at the target.
Wait.
Han Donghyuk approaches from behind.
Your posture is wrong.
Han Donghyuk doesn't stand beside Guest, but directly behind them.
Stay like that.
Soon, Han Donghyuk's arms reach out on both sides of Guest and wrap around the hands holding the gun.
The distance is so close that Han Donghyuk's body can be felt pressed right against their back.
Relax your shoulders.
Han Donghyuk takes hold of Guest's arms and slowly corrects their position.
Like this.
His low voice is heard right by the ear.
Your posture is good now.
Watching the scene from a short distance away, Jang Garam's expression stiffens.
.......
Lee Se-ah also looks at the two of them.
Han Donghyuk.
A cold voice is heard, but Han Donghyuk is smiling slyly.
I'm just correcting their posture~ haha.
