Seoryeong was immediately punched in the stomach.
As she fell, a second kick came.
Song Ukchan's fighting ability—using fists and feet—looked like someone who had **seriously trained** in boxing. Seoryeong quickly raised her elbow to protect herself, but his fist still broke through her defense with excruciating pain.
Seoryeong's arm went numb, and the side of her body ached intensely.
_If I hadn't had the protector on, this pain would have been unbearable._
As she was constantly being hit, her eyes suddenly met Lee Wooshin's.
A strange feeling made her turn her head back toward Song Ukchan.
"Ugh... Your name is Song Ukchan, right?"
As soon as she finished speaking, a fist slammed into her face hard.
As soon as she provoked him, Song Ukchan clearly became **enraged**. He continued to punch Seoryeong's face relentlessly, which immediately silenced the room.
Seoryeong raised her hands to protect herself and thought calmly.
_There are no rules in this fight. I can use all my skills._
As soon as she thought that, she didn't wait or defend anymore.
Seoryeong immediately attacked Song Ukchan's weak point accurately and quickly climbed onto his body.
"——!"
She jumped up to Song Ukchan's shoulders in an instant, then locked her arms around his neck in a **chokehold**.
When Seoryeong's elbow pressed against Song Ukchan's neck, he let out a sound of pain.
Although Song Ukchan tried to punch to fight back, Seoryeong instead tightened her arm lock like a snake coiling around its prey.
"Wow... That's a jiu-jitsu move, right?"
"Is that jiu-jitsu... or not?"
"Huh...? Isn't it? It looks similar..."
The teammates who were watching began to murmur, while the instructor who was supervising also furrowed his brow in confusion.
Jin Hoje closed his mouth and asked in a low voice.
"Chief, what kind of move is that?"
"That's just a dirty fight. No special moves."
"Huh...? That? But Song Ukchan can't move at all."
"Then what about Seoryeong? She kept getting hit, right?"
Lee Wooshin gritted his teeth tightly, staring at the duel without blinking.
"Fortunately, she's wearing a head guard. That move could definitely knock Song Ukchan unconscious. She's willing to **ignore her head**, no matter how swollen or bloody it gets from the punches."
"......"
"Even though she kept getting hit, she never closed her eyes."
"Huh?"
"Whether it was a coincidence or she was paying close attention, she waited and attacked **precisely**. Although not very strong, she's very fast and flexible. It's no wonder she's the type who endures pain."
Jin Hoje wasn't sure if his chief was praising or criticizing Seoryeong.
"What should I do with this woman's madness?"
Lee Wooshin muttered to himself.
At that moment, Song Ukchan—who couldn't endure it anymore—slammed into the floor. He took the opportunity when Seoryeong was off guard and grabbed her arm, then twisted his body until she was under him.
He gasped for breath and prepared to punch Seoryeong again.
"**Stop now!**"
A voice that sounded comical yet authoritative interrupted the tense atmosphere.
Song Ukchan paused for a moment, but still raised his hand.
Suddenly, a loud **"thwack!"** sound was heard—Song Ukchan's head was kicked forcefully.
"Didn't you hear the instructor say to stop?"
Lee Wooshin kicked the side of Song Ukchan's head hard, until it sounded like a melon breaking.
Song Ukchan fell while holding his head, while Lee Wooshin ruthlessly ordered him to get up.
At the same time, Seoryeong—whose situation had just been reversed—quickly got up, even though she felt the **cold gaze** of Lee Wooshin, which seemed to criticize her.

## — Krav Maga —
"What I'm going to teach you today is the military martial art, **Krav Maga**."
Lee Wooshin said as he removed the protector from Song Ukchan with his own hands. Then, he carelessly threw the removed protector onto the floor.
"It is a martial art based on human **instinctual reactions**. The faster your instincts and reactions, the faster you will learn—regardless of age, gender, or physical strength."
His sly eyes looked at Seoryeong.
"And most importantly, this art can be used to fight **armed enemies** with bare hands—"
He pulled a gun from his waist and quickly loaded a bullet.
"Want to try taking my gun?"
"......!"
He handed the gun to Song Ukchan, who was still confused after being hit in the head earlier.
Song Ukchan looked bewildered by the situation that had unfolded so quickly. He hesitantly accepted the gun.
As Song Ukchan stood holding the gun uncertainly, Lee Wooshin laughed and gently patted his face.
"Come on, Song Ukchan, try to aim."
Everyone in the room stared in bewildered silence, while Song Ukchan raised the gun.
The instructor demonstrated his skill by quickly **flicking** the gun out of his hand.
"After you divert or evade the enemy's attack—"
Song Ukchan's gun slipped from his grasp and fell right at Seoryeong's feet.
From there, Lee Wooshin began to act seriously.
He kicked Song Ukchan in the stomach, followed by locking his arm and hitting his chin. Song Ukchan tried to resist, but couldn't fight back.
"The main targets are the eyes, nose, chin, neck—"
"Argh...!"
Every time Lee Wooshin mentioned a specific body part, he attacked that point with **extreme precision**.
"And the groin area."
"Argh...!"
"If the attack is accurate, it can **kill** the enemy. So, remember that."
Blood flowed from Song Ukchan's nose while he couldn't fight back against the incoming attacks. His teammates sat upright and didn't dare say anything.
The atmosphere around them became extremely silent, as if weighed down by pressure.
_So that's a sandbag human, huh?_
Song Ukchan began to understand the situation and showed a slightly hardened expression. However, Lee Wooshin continued his teachings with a bored look.
"Most techniques are designed to inflict **maximum damage** on the enemy. Start by using your elbow to strike the chin."
"Ugh..."
"Continue with the neck, strike the upper abdomen and stomach."
"Ugh..."
"And kick the shin."
The sound of heavy impact filled the room as Song Ukchan was hit hard.
He fell to the floor, his body trembling slightly.
Lee Wooshin casually straightened his neck while walking past his body lying on the floor.
"Krav Maga is more about **technique** than physical strength."
His eyes fixed on Seoryeong without hiding his curiosity.
"Do you understand?"
At that moment, Seoryeong felt something **strange** inside her.
It was as if something was being triggered in her chest. Her fingertips began to feel slightly hot, as if she had been injured somewhere.
"In conclusion, don't let a larger enemy defeat you easily. In a critical situation, you must use **everything you have**—whether it's a pen or your fingers—to stab as hard as you can."
At the same time, Lee Wooshin picked up the fallen gun and pressed the muzzle against Seoryeong's forehead.
The coldness of the gun made her body stiffen instantly.
He observed her reaction with satisfaction, and at that moment, he pulled the trigger.
"——!"
However, instead of the sound of a gunshot, what was heard was the sound of a transparent **soap bubble** floating out.
Seoryeong blinked rapidly and sighed as soon as she realized she had been tricked.
She gritted her teeth and glared at him angrily, but he simply turned his body and walked toward the other teammates while summarizing the lesson.
The floating soap bubble touched Seoryeong's forehead and burst.
She frowned and repeatedly wiped the slippery soap from her forehead with her hand.

## — That Night —
After that, she was called back for combat training, and the results were not much different.
She was hit, and then retaliated, in almost the same way.
As she moved wildly, the strange feeling she had felt earlier disappeared—until she couldn't remember it anymore.
That night, as usual, she was attacked without warning and once again thrown into the sea.
The cold water hit her like a thousand knives.
She gasped, treading water, her muscles screaming in protest.
But she didn't cry out.
She didn't ask for help.
She just kept swimming, kept moving, kept **surviving**.
Because that was the only thing she knew how to do.
And somewhere in the darkness, she knew Lee Wooshin was watching.
Always watching.
Waiting to see if she would break.
But she wouldn't.
Not yet.
Not ever.
