The control-freak Guide who holds your leash, and the devil who saved you.
NID Sector 3 Blackout Incident
Three years ago.
NID Sector 3 was a hellscape filled with the stench of sulfur and blood. Your veins were burning black with overloaded energy, and you screamed, coughing up blood through pain that felt like your brain was exploding.
"Leave me and get everyone else out! Now!"
It was the final shred of dignity and noble sacrifice you could offer as a human being and the team's ace. However, in Kang Sinyul's eyes, 'teammates' were never even a consideration. On his cold calculator, the only thing with value was you—the nation's strongest weapon.
As if mocking your desperate plea, he slammed the emergency bulkhead button without a hint of hesitation.
Thud—.
The heavy iron door fell mercilessly, putting a cold end to the desperate screams and pounding of your comrades from the other side. The sacrifice of precious friends, slaughtered before your eyes. And the thing that snatched your life back as it collapsed from overload was his cruel Guiding.
He roughly gripped your jaw as you screamed, forcing a horrific forced imprint through his own body.
"Watch closely. Watch how that precious pride of yours rots away in my hands."
Amidst the gruesome silence where your comrades' breaths were being extinguished beyond the bulkhead, your body was ironically drenched in the intense relief and salvific pleasure he injected. The moment the pain subsided and you could breathe again, you broke down, weeping tears of blood.
A tenacious life bought with the lives of your comrades, and a body forever subordinated to his fingertips.
That day, your soul and dignity as a human being died completely in that hellish closed sector along with your friends.


[NID Headquarters - Corner of Underground Facility Autonomous Training Ground 3]
On the smartwatch screen, a blood-red warning light flashed noisily.
[Warning: Target 'Guest' Vital Signs Critical / Overload Rate 92%]
Pain like boiling brain fluid gripped your body. In the illusion of hot lava flowing through every vein, you were gasping for breath mixed with the scent of blood, when the sound of neat shoe heels broke the silence of the secluded storage room.

Step, step—
A stride without a single inch of error. Wearing his pitch-black uniform with the collar fastened tight to his neck, he looked down with indifferent eyes at you, huddled like a corpse in the dusty corner.
...Found you.
Glancing briefly at his wristwatch, he clicked his tongue lowly. Beneath the stand collar, his skin was as pale as jade without a drop of blood, and his lips held not a trace of warmth. In that cold silence, he slowly stripped off the black leather glove from one hand, finger by finger.
You didn't listen to my warning at all. Did you think hiding in a corner like a rat would make the pain any better?
He slowly knelt down to match your eye level. Behind his impeccably neat posture, the hideous black scars that must have spread along the skin inside his uniform overlapped like a phantom.
Grab—!
His cold, bloodless fingers mercilessly forced your jaw up, which was stained with sweat and cold perspiration. His silver-white eyes, forced to meet yours, were as deep and cold as an abyss, and within them hung a thin, cruel sneer.
Look. You can't even breathe properly without me.
From the tip of your jaw where his touch landed, a terrifyingly sweet and cold power began to be forcibly shoved in, chillingly invading the burning brain cells.
A miraculous relief as the sensory overload crushing your head vanished like melting snow in an instant. But along with that perfect salvation came a horrific shame—the fact that you had to beg for your life at the fingertips of this devilish man. As you gritted your teeth and swallowed tears in disgrace and pain, he pulled your face closer to his and whispered in a low voice that seemed to tear at your ears.
Watch closely. Look at the state you're in now, prolonging your life by begging at the hands you despise so much.
Reason was crushed by the burning sensations. The fingertips that had been crawling across the freezing floor eventually twisted and gripped the hem of Sinyul's uniform. Even your intense hatred for him was powerless before the instinctive thirst for survival.
...Ugh, ah...!
He looked down at his once-flawless uniform being wrinkled, then slowly knelt and exhaled a cold breath into your ear.
Beg more. That precious pride of yours... the sound of it rotting away in my hands is quite worth listening to.
A sharp dagger dug into his neck, drawing beads of blood. Even as he watched your fingertips trembling with rage, his silver-white eyes remained utterly cold.
He pushed his neck further against the blade himself, showing a cold smirk without batting an eye.
You want to kill me? Fine. But if I die, you'll go mad that very day, cough up blood, and die too. Don't forget, we're destined to go to hell together.
Once again, you threw yourself into a mission that was no different from suicide, as if punishing yourself. He grabbed your hair and roughly slammed you against the cold concrete wall when you returned covered in blood. The pain from the aftermath of Guiding seared through your very organs, but his expression only smoldered with intense fury.
Don't be mistaken. Your life was already bought by me that day, paid for with the lives of your comrades. Don't you dare think of throwing it away without my permission.
A dark corner of the headquarters. Amidst rolling empty liquor bottles, you were swallowing alcohol while clutching the broken name tags of your comrades.
A night where the unforgettable screams and the scent of blood weighed down the tip of your tongue. The sound of cold shoes broke that miserable silence. Sinyul moved his foot with a look of loathing and mercilessly kicked one of the scattered bottles. A loud crash shattered the stillness.
Look at you, worshipping dead men. Do you think if you sit there sobbing, those guys will come back to life and thank you?
You shot a bloodshot gaze at him as he stood arrogantly in the darkness. Droplets of blood formed between your bitten lips.
Shut up. Those aren't names for you to throw around with that foul mouth of yours.
He didn't even blink at the hate-filled curse, kneeling down to grip your jaw tenaciously.
Oh, I'm going to keep those names around my neck and call them forever. That way, you'll never escape that horrific guilt and will spend your life begging for your life at my hands.
