Jongho was twelve years old the first time he understands what loyalty costs.
There’s blood on the pavement—too dark, too much of it—and the man on the ground isn’t moving anymore.
Jongho doesn’t know his name. He’s told later that names don’t matter in this line of work. What matters is who gave the order, and who carried it out.
Your brother is standing beside him.
Not yet the man he’ll become, but already dangerous in that quiet, inevitable way.
He places a hand on Jongho’s shoulder—not comforting, not cruel. Just grounding.
“You didn’t look away,” your brother says.
Jongho swallows. His hands are shaking, but he keeps them at his sides.
“I didn’t,” he replies.
That’s when your brother decides Jongho will belong with him.
───────── ⋆⋅☆⋅⋆
─────────
Jongho grows up fast after that.
Too fast.
He learns how to fire a gun before he learns how to dream. Learn how to break bones without leaving marks.
Learn how to listen without speaking, how to stand without flinching, how to obey without asking why.
Your brother saves him from the streets. Gives him food.
Shelter. Purpose.
And Jongho repays that debt with absolute devotion.
He becomes the man sent when things need to be finished. Not loud. Not cruel. Just effective. The kind of man people whisper about but never really see.
By the time Jongho is twenty, he has a reputation.
By the time he is twenty-three, he has a body count.
And by the time he is twenty-six, he believes there is nothing left inside him that can be ruined.
That’s when you enter the picture.
Jongho hears about you long before he meets you.
Not in detail. Just fragments.
My sister’s in town. She’s staying at the house for a while.
Keep an eye out, yeah?
It’s said casually, like you’re an afterthought.
You are not supposed to matter to him.
The first time Jongho sees you, it’s late.
The house is quieter than usual—guards posted outside, lights dimmed. Jongho’s there to report on a shipment gone wrong, blood still drying beneath his sleeves.
You’re in the kitchen.
Barefoot. Wearing one of your brother’s old shirts, sleeves too long, hair loose like you don’t know what kind of house this really is.
You’re standing on your toes, trying—and failing—to reach something on the top shelf.
Jongho stops short.
This is wrong. Instinctively, immediately wrong.
You turn when you hear him.
“Oh—sorry,” you say, startled. “I didn’t know anyone else was here.”
Your voice is soft. Normal. Untouched.
Jongho doesn’t move.
You smile, a little awkward, and step aside. “You can go ahead. I’m just stealing snacks.”
Stealing.
From a house built on blood money.
Something in Jongho’s chest tightens.
───────── ⋆⋅☆⋅⋆
─────────
Your brother finds you talking to Jongho ten minutes later.
He freezes.
Not visibly. Not in a way anyone else would catch. But Jongho sees it—the subtle shift, the sharp attention.
“Hey,” you say easily. “Your friend was helping me find—”
Your brother cuts in. “You shouldn’t bother him.”
Jongho stiffens. “It’s fine.”
“It’s not,” your brother says, too quickly. Then, correcting himself, calmer: “He’s working.”
You glance between them. “Right. Sorry.”
You walk away without argument.
Jongho watches you go, unease pooling in his gut.
Later, your brother corners him in the hallway.
“Don’t get attached,” he says quietly.
Jongho frowns. “To what?”
“To her.”
There it is.
“She’s not part of this world,” your brother continues. “She never will be. And I won’t have you dragging her into it.”
Jongho nods immediately. “I understand.”
He means it.
At least, he thinks he does.
From that night on, Jongho avoids you.
Not obviously. Just enough.
If you enter a room, he leaves.
If you speak to him, he answers politely, briefly.
If you smile, he looks away.
It works. For a while.
Until one afternoon, you corner him in the hallway.
“Did I do something wrong?” you ask.
He hesitates.
“No.”
“Then why do you act like I’m invisible?”
Because you’re not supposed to exist to him. Because caring about you would be a weakness.
Because your brother is right.
Jongho lowers his gaze. “It’s safer this way.”
“For who?” you ask.
He doesn’t answer.
That’s the first lie he tells you.
And it’s the one that will eventually destroy everything.
───────── ⋆⋅☆⋅⋆
─────────
Avoiding you becomes Jongho’s second job.
He learns your schedule without meaning to. The times you wake, the way you linger in doorways like you’re undecided about the world, the habit you have of humming under your breath when you’re bored. He notices all of it while pretending he doesn’t.
That’s the problem.
Watching is what he’s good at.
You notice him too, of course. You’re not stupid. You catch the way his eyes flick to you and then away. How conversations stop when you enter a room. How your brother suddenly insists you don’t go out alone anymore.
“You’re acting weird,” you tell your brother one night.
He exhales through his nose. “This life isn’t safe.”
“I know that.”
“You don’t,” he says sharply, then softens. “Just—trust me.”
You do. You always have.
Jongho hears the whole thing from the hallway. He hates that your trust is so easy. He hates that it makes him want to deserve it.
The second message is clearer than the first.
A photograph. Grainy. Taken from across the street.
It’s you, stepping out of a café. Laughing at something on your phone. Unaware.
Jongho feels something cold slide down his spine.
Your brother stares at the image for a long time before he finally speaks. “They’re testing me.”
Jongho already knows what comes next.
“She needs eyes on her,” your brother continues. “All the time.”
Jongho doesn’t hesitate. “I’ll do it.”
Your brother looks up, surprised. Not suspicious. Just… thoughtful.
“You sure?”
“Yes.”
It’s not the right answer.
It’s the only one Jongho can give.
───────── ⋆⋅☆⋅⋆
─────────
You find out over breakfast.
“What do you mean I have a bodyguard?” you demand.
“Not a bodyguard,” your brother corrects. “Protection.”
“That’s the same thing.”
“It’s Jongho.”
You stop mid-sentence.
Your eyes flick to him instinctively, like you’re looking for confirmation. Jongho keeps his face neutral, hands folded neatly in front of him.
“You?” you say. “Why you?”
“Because I trust him,” your brother answers.
You laugh once, incredulous. “You barely let him look at me.”
Jongho’s jaw tightens.
“This isn’t permanent,” your brother adds. “Just until things settle.”
You cross your arms. “And I don’t get a say?”
“No.”
You look at Jongho again, sharper this time. “Do you want this job?”
It’s the first time you’ve ever asked him what he wants.
Jongho meets your gaze.
“Yes,” he says quietly.
You don’t know it yet, but that word seals your fate.
Being assigned to you changes everything.
Jongho walks behind you now—not out of avoidance, but strategy. His presence is constant, unavoidable. You feel it like pressure at your back.
“You’re staring,” you accuse one afternoon.
“I’m watching.”
“That’s worse.”
“Get used to it.”
You roll your eyes, but there’s no real bite to it. You’re adjusting faster than he expects. Asking questions. Testing him.
“What happens if I run?”
“I catch you.”
“What if I scream?”
“I remove the threat.”
“What if the threat is you?”
Jongho stops walking.
You turn, startled by the sudden stillness. His expression is unreadable, but his voice is careful when he answers.
“Then I remove myself.”
Something twists in your chest at that.
You don’t run anymore.
───────── ⋆⋅☆⋅⋆
─────────
It happens in a crowd.
Someone bumps into you hard enough to knock you off balance. Before you can fall, Jongho’s hand closes around your wrist.
Firm. Certain.
Alive.
It lasts less than a second. He lets go immediately, like he’s burned.
“Sorry,” he mutters.
You stare at your wrist long after he’s released it. The warmth lingers.
That night, Jongho washes his hands twice.
───────── ⋆⋅☆⋅⋆
─────────
You start noticing the cracks in him.
The way his shoulders tense when your brother raises his voice.
The scars you glimpse when his sleeves ride up.
The exhaustion he carries like something permanent.
“You ever sleep?” you ask.
He answers honestly. “Lightly.”
“Why?”
“So I don’t miss anything.”
“Like what?”
He looks at you then. Really looks.
“Like you.”
That’s when it starts to become dangerous.
───────── ⋆⋅☆⋅⋆
─────────
Thunder wakes you.
It’s loud enough to rattle the windows, close enough that the air feels charged. Your heart kicks hard against your ribs before you can stop it.
You sit up, breathing shallow.
The hallway light is on.
You open your door.
Jongho is sitting on the floor outside it.
Back against the wall. Knees bent. Gun resting in his hand like an extension of his body.
“You’re serious,” you whisper.
He looks up instantly. “Did I wake you?”
“No,” you say. “I woke you.”
A pause.
“I can move.”
“…don’t.”
He stays.
And somewhere deep in his chest, something gives out.
───────── ⋆⋅☆⋅⋆
─────────
It happens on a night that’s supposed to be normal.
You’re leaving a restaurant—late, laughing, distracted in that way Jongho has learned to hate because the world never deserves your carelessness. The street is crowded, lights reflecting off wet pavement, noise blurring the edges of danger.
Jongho feels it before he sees it.
A shift. A wrongness.
“Stay close,” he murmurs.
You don’t have time to ask why.
A man steps into your path too smoothly, smile too rehearsed. Another appears behind you.
The crowd keeps moving, unaware.
“Wrong girl,” Jongho says calmly, already positioning himself between you and them.
One of the men laughs. “Doesn’t look wrong to me.”
The hand that reaches for you never makes it.
Jongho moves fast—faster than you’ve ever seen him move. There’s a sharp crack, a gasp, and suddenly one man is on the ground, wrist bent at an angle that makes your stomach lurch.
The other pulls a knife.
Jongho doesn’t raise his voice. Doesn’t rush.
He disarms him in three precise motions and slams him into the brick wall hard enough to knock the air from his lungs.
“You don’t touch her,” Jongho says softly. “Ever.”
Sirens wail somewhere distant.
Jongho grabs your hand—this time he doesn’t hesitate—and pulls you away.
You don’t speak until you’re safely inside the car.
Your hands are shaking.
“So,” you say faintly, “that’s what you do.”
Jongho grips the steering wheel. His knuckles are white.
“Yes.”
You swallow. “Did you… enjoy it?”
He closes his eyes.
That's enough to answer.
That night, Jongho doesn’t sit outside your door.
You find him in the kitchen instead, blood staining the sink as he scrubs his hands too hard, too long.
“You’re bleeding,” you say.
“It’s not mine.”
The words chill you.
“You scared me,” you whisper.
He finally looks at you then. Really looks. His eyes are dark, conflicted, raw.
“I scared myself.”
You step closer before you can think better of it. Gently, you take his wrist, still his shaking.
“Thank you,” you say. “For protecting me.”
Something in his face fractures.
“You shouldn’t thank me,” he says hoarsely. “Not for this.”
“Why?”
Because he liked it. Because it felt right.
Because hurting someone for you felt dangerously close to purpose.
“I crossed a line,” he says instead.
You don’t let go.
───────── ⋆⋅☆⋅⋆
─────────
Your brother notices immediately.
Not the bruises. Not the rumors. The change.
Jongho is sharper now. More alert. More volatile in ways only someone who knows him intimately would see.
And you.
You stand closer to him without realizing it. You glance at him before answering questions. You trust him instinctively.
Your brother watches it all with narrowing eyes.
One night, he corners Jongho alone.
“You’re getting sloppy,” he says.
“I’m efficient.”
“You’re emotional.”
Jongho stiffens. “No.”
“She’s affecting you.”
A beat.
“Is that a problem?” Jongho asks.
Your brother studies him carefully. “It is if you forget where you belong.”
Jongho doesn’t answer.
For the first time in years, silence is not obedience.
───────── ⋆⋅☆⋅⋆
─────────
It’s raining. Hard.
You’re stuck waiting in the car while Jongho deals with something inside one of your brother’s properties. The storm rattles the windows, thunder cracking overhead.
Your breathing quickens before you can stop it.
By the time Jongho returns, you’re curled into yourself, eyes glassy.
“Hey,” he says softly, instantly kneeling in front of you. “Hey. Look at me.”
You try. Fail.
He hesitates—just a second—then pulls you into his arms.
You cling to him.
He smells like rain and metal and something warm beneath it all.
“It’s okay,” he murmurs, hand steady on your back. “I’ve got you.”
Your face is pressed against his chest. His heartbeat is fast. Too fast.
You look up.
He’s too close.
Too gentle.
For a moment—just one—he leans down.
Stops.
His forehead rests against yours instead.
“I can’t,” he whispers.
You nod, even though your chest aches.
“Okay.”
───────── ⋆⋅☆⋅⋆
─────────
The next threat is deliberate.
A package. No return address.
Inside: a phone.
It rings once.
Your brother answers on speaker.
A distorted voice speaks.
“You’ve got something we want.”
Your brother’s gaze flicks to you.
Jongho steps forward instinctively, positioning himself in front of you without thinking.
“We can make this easy,” the voice continues. “Or we can make it hurt.”
The call ends.
Silence crashes down around you.
Your brother exhales slowly.
“They’re escalating.”
Jongho already knows what this means.
You are no longer collateral.
You are the target.
And Jongho realizes, with sickening clarity, that there will come a moment when he’ll have to choose.
Between the man who saved him. And the girl he’s already lost himself to.
Jongho doesn’t sleep that night.
He sits at the small table in the corner of his apartment, gun disassembled in front of him, cleaning each piece with methodical care. It’s muscle memory—something to keep his hands busy while his thoughts spiral.
You’re down the hall, asleep. Or trying to be.
He can hear the way you shift in bed. The soft hitch in your breathing that tells him you’re dreaming badly.
That’s when it hits him.
Not like lightning.
Like gravity.
This is it.
This is the thing he was trained his entire life to avoid.
If they take you, he will burn the world.
If your brother orders him away, he will disobey.
If loving you means dying, he will not hesitate.
There’s no version of the future where he survives this untouched.
Jongho closes his eyes.
He is in love with you.
───────── ⋆⋅☆⋅⋆
─────────
The next morning, you find him on the balcony.
He hasn’t slept. You can tell by the shadows under his eyes, the way his shoulders are too tense, like he’s holding himself together by force alone.
“You okay?” you ask gently.
He nods. Then shakes his head.
“Come here,” he says quietly.
You do.
He doesn’t touch you. Just stands close enough that you can feel his warmth, his presence steady and grounding.
“If anything happens,” he says, voice low, “you listen to me. You don’t argue. You don’t hesitate.”
You frown. “That sounds ominous.”
“I’m serious.”
“So am I,” you reply. “You’re not allowed to disappear on me.”
Something flashes in his eyes—pain, affection, resignation.
“I would never leave you,” he says.
Not won’t.
Wouldn’t.
The distinction terrifies you.
Your brother calls Jongho alone that night.
The room is dim, heavy with cigar smoke and unspoken truths. Your brother doesn’t waste time.
“They want leverage,” he says. “And you’re too close.”
Jongho doesn’t pretend not to understand.
“You’re stepping back,” your brother continues. “Effective immediately. Another team will handle her security.”
“No.”
The word is quiet. Firm.
Your brother’s gaze sharpens. “That wasn’t a suggestion.”
“She trusts me.”
“That’s the problem.”
Silence stretches.
“You taught me loyalty,” Jongho says carefully. “You taught me protection. I’m doing exactly what you trained me to do.”
Your brother stands. Walks closer.
“I taught you to choose the family,” he says. “Not yourself.”
Jongho meets his eyes.
“I am.”
The room goes cold.
───────── ⋆⋅☆⋅⋆
─────────
You feel it immediately.
Jongho pulls back. Not physically—he’s still there, still guarding you—but something vital withdraws. His voice is clipped. His eyes never linger.
“Did I do something?” you ask finally.
“No.”
“You’re lying.”
He exhales slowly. “I’m trying to keep you safe.”
“By freezing me out?”
“By not wanting what I shouldn’t.”
The words slip out before he can stop them.
Your heart stutters. “And what’s that?”
He looks at you like you’re the answer and the problem all at once.
“You,” he says.
The air between you crackles.
You step closer. “Then stop fighting it.”
He takes a step back instead, jaw clenched.
“If I stop,” he says hoarsely, “everything falls apart.”
The attempt happens two days later.
A staged accident. A car that doesn’t stop. Glass shattering. Screams.
Jongho sees it unfold in slow motion.
He throws himself between you and the impact, slamming you to the ground as the car clips his shoulder and spins out.
Pain explodes down his arm.
You’re crying. Shaking. Alive.
That’s all that matters.
Sirens scream closer.
Jongho presses his forehead to yours briefly, fiercely.
“That’s it,” he whispers. “I’m done listening.”
“What?”
“I’m taking you out of here.”
“You don’t have permission—”
“I don’t care.”
And in that moment, Jongho chooses.
Not the family. Not the debt.
Not the man he was made to be.
He chooses you.
───────── ⋆⋅☆⋅⋆
─────────
Jongho moves fast.
Cash. Documents. New phones. He’s been preparing for this possibility longer than he ever admitted to himself.
You watch him pack with shaking hands.
“You’re serious,” you whisper.
“I always am.”
“What about my brother?”
Jongho pauses.
“I’ll handle him.”
He doesn’t explain how.
When you reach the door, he stops you.
“There’s something you need to understand,” he says quietly. “Once we leave, there’s no going back.”
You look at him—really look at him. The man who stood outside your door. Who bled for you. Who loved you in every way except the one he wasn’t allowed to.
You nod.
“Then don’t leave me behind.”
He cups your face, finally—finally—and presses his forehead to yours.
“I never could.”

You frown. “That sounds ominous.”
“I’m serious.”
“So am I,” you reply. “You’re not allowed to disappear on me.”
Something flashes in his eyes—pain, affection, resignation.
“I would never leave you,” he says.
Not won’t.
Wouldn’t.
The distinction terrifies you.
───────── ⋆⋅☆⋅⋆
─────────
The city looks different at night when you’re not sure you’ll ever see it again.
Streetlights blur past the car windows as Jongho drives with one hand on the wheel, the other resting near the gun tucked under his jacket.
His jaw is tight, eyes sharp, scanning mirrors and shadows like the past might physically reach out and grab you.
You don’t speak.
Every word feels too loud.
When you cross the city line, something in your chest loosens—and tightens all at once.
“Are we safe?” you whisper.
Jongho doesn’t lie. “Not yet.”
The safehouse is small, anonymous, tucked into a stretch of highway no one looks at twice. Jongho checks every room before letting you inside.
He locks the door. Then the windows. Then the door again.
Only when everything is secured does he finally sag against the wall, breath shuddering out of him.
“You’re hurt,” you say.
“It’ll heal.”
You step closer. Gently, you take his injured arm, guiding him to sit.
As you clean the cut, you notice how still he is. How careful.
“You don’t trust yourself,” you murmur.
He swallows. “I trust myself too much.”
Sleep doesn’t come easily.
You lie on the narrow bed, listening to Jongho move around the room. He stops just short of the mattress.
“I’ll take the floor.”
“You’re injured.”
“I’ll be fine.”
You reach out, fingers brushing his sleeve.
“Stay.”
He hesitates.
Then, slowly, he lies beside you—careful not to touch, not to crowd.
The space between you is unbearable.
“You don’t have to be afraid,” you whisper.
“I’m not afraid of you,” he replies softly. “I’m afraid of what I’d do for you.”
You turn, facing him.
“Then do it.”
He exhales, shaky. Wraps an arm around you like he’s holding something fragile.
For the first time, he sleeps deeply.
───────── ⋆⋅☆⋅⋆
─────────
Your brother doesn’t call.
That’s worse than anything.
Jongho knows what silence means. Retaliation isn’t loud—it’s patient.
Days pass. Then weeks.
You move again. Then again.
Each place is smaller, quieter. Each one costs Jongho a little more of himself.
He takes work where he can—construction, repairs, anything honest enough to keep you fed and hidden. His hands grow rougher, his shoulders heavier.
But at night, he softens.
He learns how to make you laugh again. Learns how to cook badly but earnestly. Learns how to touch you without fear.
“You could’ve left,” you say one night.
He presses a kiss to your hair. “Never.”
Jongho carries it like a second spine.
Every time you flinch at a loud noise.
Every time you ask about your brother and he doesn’t answer.
Every time you look at him with trust instead of fear.
“I stole you,” he says once, voice raw.
“You chose me,” you reply.
“That doesn’t make it better.”
“It makes it ours.”
He doesn’t argue—but the guilt never leaves. It just settles deeper.
───────── ⋆⋅☆⋅⋆
─────────
It’s a stranger who lingers too long at the gas station.
Jongho notices immediately.
That night, he packs again.
“We can’t stay,” he says.
You grab his wrist. “We’re always running.”
“I won’t let them find you.”
“What about what I want?”
He freezes.
Slowly, he turns to face you.
“I want a life,” you say. “Not just survival.”
For a long moment, Jongho says nothing.
Then he nods. “Then we stop running.”
───────── ⋆⋅☆⋅⋆
─────────
You settle in a town small enough to forget the world.
Jongho builds a routine. A real one. Morning coffee. Honest work. Evenings spent with you on the couch, your feet tucked under his thigh.
He starts laughing more.
You start sleeping better.
For the first time, Jongho lets himself believe.
Maybe this is enough.
───────── ⋆⋅☆⋅⋆
─────────
Your brother finds you on a quiet morning.
He looks older. Tired. Human.
Jongho steps in front of you instinctively.
“I trusted you,” your brother says.
“I know.”
“You broke that trust.”
“Yes.”
A pause.
“You kept her alive,” your brother says quietly.
Jongho nods. “That was the point.”
Your brother lowers his gun.
“Take care of her,” he says.
Jongho bows his head. “With my life.”
───────── ⋆⋅☆⋅⋆
─────────
Years later, when the world is quieter, Jongho holds you like he’s still afraid you might disappear.
“I was made to be a weapon,” he murmurs.
You kiss his scars. “And now?”
“And now,” he says, pressing his forehead to yours, “I’m just a man who chose love.”
He swore to protect you.
He did.
Just not from himself.
