Chapter 3
The reason was simple.
Patients coming to the endoscopy room visited the restroom frequently. Very frequently.
Some used the toilet dozens of times each, and no matter how much she cleaned and cleaned again, the restroom never seemed clean.
Scrubbing the toilet day after day brought tears to her eyes.
[Announcement: The janitor in charge of the 5th floor endoscopy room is requested to promptly tidy the menâs restroom. Once againâ]
Cheong-ah grabbed her hair in frustration at the loud announcement echoing through the hallway.
This meant someone had done something awful in the restroom again.
âI just cleaned the toilet ten minutes ago!â
âUndercover investigation my foot. Iâve been scrubbing toilets all day!â
Grabbing her mop, she solemnly headed toward the restroom.
The reason Cheong-ah had been assigned to the 5th floor wasnât special.
Probably because other janitors didnât want to deal with it.
Ah, maybe the previous person had spent all day cleaning the toilets, suffocated from the stench, and ran away.
The truth was probably just that.
As she rounded the corner toward the restroom, the end of her vigorously swung mop sank with a soft âplopâ into something soft.
And then,
âUgh?!â
With that sound, something seemed to collapse from beyond the wall in slow motion.
A white coat fluttered and fell, covering the floorâor rather, Cheong-ah herself.
âHuh?â
The person falling toward her appeared to be a male medical staff member.
Even though his small face was half-hidden behind a medical mask, it was clear he was making a rather troubled expression.
Instinctively, Cheong-ah twisted her body to avoid him. The man, having no support, collapsed onto the floor with a thud.
âWah?! Are you okay?â
Cheong-ah grabbed the man, who was crouched over, shaking him.
He clutched his lower abdomenâor slightly lowerâwith trembling hands as if in pain.
Grimacing, he muttered,
âWha⊠what⊠are you?â
His hand grabbed Cheong-ahâs sleeve. Frowning deeply, he groped around.
âY-You⊠damn⊠CheonghwaâŠ?â
Cheong-ahâs expression froze. The manâs fingers, which had hesitated, began to lose strength.
Cheonghwa?
Cheong-ah frowned as she examined the unconscious man.
Though muffled by his mask, he had clearly said âCheonghwa.â
Who was this person, and how did he know the Cheonghwa faction?
Cheong-ah quickly reached for his chest to flip over his name tag.
Department of Gastroenterology, Professor Min Yoo-shin
âProfessor?â
Cheong-ah looked around.
There was no one around the professorâs research office, which restricted public access.
Fixing her gaze on the corner, she groped the manâs back pocket and retrieved his wallet.
She confirmed his name, Min Yoo-shin, from both his ID and credit cards.
It took less than a minute to verify everything with just one hand.
Of course, her other hand was checking his pulse. She couldnât afford to let anyone get hurt due to her mistake.
Pulseâslow, but thankfully normal.
She flipped his eyelids to check his pupils, but it was difficult with him already unconscious.
Finally, the most critical checkâhis groin. Thankfully, there seemed to be no bleeding.
With her eyes tightly shut, Cheong-ahâs hand moved to the manâs injured area.
âHmmâŠ? Ah? Oh!â
Her fingers trembled as they touched the waistband of his pants.
The size of the injury wasnât good. The blow from the mop to his lower area had clearly done some serious damage.
Her hand, tracing the area, recoiled in shock. It was swelling a little every time she touched it.
âThis⊠if it swells this much, it could be serious!â
Her anxious gaze darted relentlessly between his face and his injured area. The thought that leaving him like this could lead to serious trouble flashed through her mind.
âEmergency, emergency!â
Cheong-ah hastily slid her hands under his armpits and bent her knees slightly to start dragging his body.
âUgh! What theâŠ!â
He was tall, but could he really be this heavy?
Cheong-ah, with superior strength and stamina compared to most women, struggled.
Even from just feeling the firmness of his latissimus dorsi and pectoral muscles under her hands, she could tell he was quite muscular, despite appearing thin.
Of course, that made him heavy.
Her lower back trembled as she exerted force to pull him.
âWhat do I do! This is badâŠ!â
Tears streaming, Cheong-ah dragged his body with all her might toward the endoscopy room, where medical staff gathered.
Sweat poured down with every step.
âHelp me!â
Cheong-ah finally reached the endoscopy room and called for help. A passing nurse, startled to see them, exclaimed,
âOh my! Professor!â
Squeals echoed through the hallway.
The nurse ran inside and shouted something, and medical staff quickly gathered.
Cheong-ah panted, tears on her face, still dragging Yoo-shinâs unconscious, limp body.
âHe collapsed in the hallway!â
âPrepare the cart! Call the CPR team!â
âHe⊠he was hit in the groin by a mop as he fell!â
âOh my!â
Though the sequence was a bit off, all the important information had been conveyed.
A mobile stretcher was prepared, and the medical staff skillfully lifted Min Yoo-shin onto it.
âBe careful moving him! One, two, three!â
Even unconscious, Yoo-shin grimaced in pain, curling his body.
âS-Sorry,â Cheong-ah silently apologized, then quickly ran back toward the professorâs office she had been cleaning.
Once again, an announcement sounded through the hospital, requesting the restroom be cleaned.
âIâm coming, Iâm coming!â
Grabbing her scattered mop, Cheong-ah ran toward the restroom, making a phone call at the same time.
[Wang. Good morning, senior!]
It was Yeon-hee, a sergeant from the Central Cheong information analysis division.
âYeon-hee, I need your help!â
[What is it? Something interesting?]
Yeon-heeâs voice on the other end seemed to sparkle with excitement.
âName: Min Yoo-shin. Age: 33. Professor, Department of Gastroenterology, Boksan University Hospital. Tail him. Itâs urgent.â
Cheong-ah recited the information she had just confirmed from his ID.
The sound of typing on the other end stopped, and soon Yeon-heeâs laughter rang out.
[What? Where did you find such a good-looking guy?]
Good-looking?
Cheong-ah paused mid-scrub, rebutting awkwardly,
âNot that. Heâs suspicious.â
[Why? Thereâs nothing suspicious. Heâs a respectable professional, living in a great house. Just seems like a silver spoon.]
Despite Yeon-heeâs explanation, Cheong-ahâs face darkened with suspicion. She stopped scrubbing and lowered her voice.
âIâm currently undercover in the hospital. The moment he saw me, he asked if I was Cheonghwa faction.â
There was a bustling sound as Yeon-hee seemed to adjust her posture.
[Really? That Cheonghwa that made our drug task force chase its own tail? He suddenly asked you that out of nowhere?]
âI⊠kind of⊠hurt him. At that moment, he urgently asked if I was Cheonghwa. Iâm undercover as Park Bok-seon, so he probably didnât say my real name.â
[Thatâs even more suspicious.]
âRight? Anyway, one thingâs certain. I just had a gut feeling.â
A brief silence passed.
Yeon-hee never considered Cheong-ahâs instincts mere hunches.
Graduating top of her class from the police academy, memorizing historical case records, with field experience addedâCheong-ah was like a human supercomputer of information.
And her conclusions often surpassed system predictions.
The problem was Cheong-ah herself could rarely explain how she reached them.
She always described it as âIâve got a bad feelingâ or âI smell a crime.â
Most people would just think, Detective Kim Cheong-ah has good instincts.
But Yeon-hee knew better.
âThis isnât instinctâitâs high-performance forensic calculation inside her brain that even AI canât match, you fools!â
Without hesitation, Yeon-hee started acting on Cheong-ahâs lead.
[Okay. Iâll tail him a bit more. Whatâs confirmed for now is heâs probably exempt from military service⊠something like that.]
âMilitary exemption?â
[Heâs 33 and a professor. Thereâs no way otherwise.]
âAh, that makes sense. He looks fine, so why would he be exempt? Got it. Thanks a lot!â
Cheong-ah smiled as she looked at the now sparkling clean toilet.
