Katherine had never believed in happy endings.

Not when her earliest memory was a smoke-choked room and a gunshot.

Not when she learned to stitch her own wounds at nine.

Not when she learned how to smile at monsters so they’d let her live another day.

The underground syndicate she grew up in had a simple rule: you either become a weapon… or you become a corpse. She chose to become a weapon. Years passed. She learned to fight, shoot, and kill. Then one night—bruised, bloodied, and sick of surviving instead of living—she escaped. And never looked back.

She built something legitimate, something powerful in corporations, investments, influence.

People called her undefeated.

Untouchable.

UnbreakablOne

One night, after a 16-hour workday, Katherine sat alone in her penthouse with nothing but silence and a book—the novel that had kept her awake for three nights in a row.

A story about a ruthless billionaire named Daniel Ford.

A boy who had clawed his way out of hell.

Alone.

Unwanted.

Unloved.

Just like her.

She traced her finger over the page where Daniel whispered to Sophia, “Tell me I matter to you.”

Her chest tightened.

Sophia never meant it.

Daniel died believing he wasn’t loved by the one person he trusted.

Katherine closed the book, whispering into the quiet room,

“He deserved better.”

After some time she fell asleep.

Katherine wasn’t sure how long she drifted in and out of consciousness.

There were moments—brief flashes—where she felt arms around her, the faint scent of clean cologne, the softness of a voice trying to reassure her. But exhaustion pulled her back under each time.

A few minutes earlier—

James Walker slammed the brakes the moment he saw a figure lying on the side of the empty road.

“What the—” His heart jumped into his throat.

He rushed out of the car, sprinting toward the unmoving woman. The streetlights cast a pale glow over her face—delicate features, soft lashes resting on her cheeks, clothes slightly dusty from the fall.

She looked like she had simply… collapsed.

James knelt beside her, panic tightening his chest.

“Miss? Can you hear me?” he asked, gently shaking her shoulder.

No response.

He checked her pulse—steady but faint. Relief washed over him. “Okay. You’re alive. Thank God.”

He looked around—no witnesses, no car nearby, no sign of an accident.

Just a girl who had seemingly fallen asleep on the road.

“Who leaves someone like this?” he muttered under his breath, anger flashing across his usually gentle eyes.

Carefully, he slid one arm beneath her knees and the other around her back, lifting her with surprising ease. Her head fell softly against his chest, her breathing warm against his shirt.

“Don’t worry,” he whispered, “I’ll get you help.”

But instead of driving her to a hospital—where media and reporters could swarm after recognizing James Walker—he drove straight to his private mansion.

His home.

The safest place he knew.

He carried her inside, ignoring the startled look from his housekeeper.

“Prepare the guest room,” he ordered. “And call the family doctor. Immediately.”

“Yes, young master.”

He laid her gently on the bed, adjusting the blanket over her.

Up close, she looked even more mysterious.

No ID.

No bag.

No phone.

Just a woman who appeared from thin air. James sat on the edge of the bed, studying her peaceful face. “Who are you…?” he whispered.

By the time the family doctor arrived, Katherine was still deeply asleep—still trapped between two worlds. Her breathing was steady, pulse normal. Nothing physically wrong.

“She’s extremely exhausted,” the doctor said. “Almost like her body and mind shut down from stress or lack of sleep.”

James frowned. Exhausted enough to collapse on a road? He glanced at her again, worry tugging at him.

“Take care of her,” he told the staff. “Stay outside her room. Call me if she wakes up.” He left, but not before looking at her one last time.

The first thing Katherine felt was softness.

A bed—far too comfortable to be hers.

A pillow that didn’t smell like her laundry detergent.

And warm air drifting from a vent, not the cold night wind she remembered.

Her eyes snapped open.

The ceiling was unfamiliar.

White. Ornate. Expensive.

Her instincts kicked in instantly. she sat up in one sharp motion, her body tense and alert. Her gaze swept the room—large, elegant, decorated in warm beige and gold.

A private residence.

A luxurious one.

Footsteps echoed softly. Katherine’s head whipped toward the sound.

A young maid entered the room carrying a tray, but the moment she saw Katherine awake—sitting straight, expression sharp—she froze. Her hands trembled, nearly dropping the tray.

“Y-You’re awake! I—I’ll inform the Young Master immediately—”

“Stop.”

The single word—cold, lethal, low—cut through the air like a blade.

The maid stiffened, turning pale.

Katherine’s eyes narrowed. “Where is this?”

The girl swallowed. “Th-this is the Walker residence, miss.”

“And why,” Katherine continued, voice icy and emotionless,

“am I here? Did you kidnap me?”

The maid shook her head so quickly it looked painful.

“N-no! Miss, please—our master brought you here. He found you on the road. You were unconscious.”

Katherine stared at her, silent, unreadable.

“Speak clearly,” she demanded.

“Who is your master?”

“Y-Young Master James Walker.”

Katherine felt the world still for a moment.

James… Walker?

Impossible.

“Fine,” she said coldly. “Call him. Tell your master I want to see him.”

“Yes, m-miss!” The maid practically ran out of the room.

Katherine exhaled quietly.

She did not panic.

She did not tremble.

She sat calmly, legs crossed, back straight, her posture sharper than broken glass.

If she was truly in the world of the novel… she needed information.

Footsteps approached again—this time heavier, steady, controlled.

The door opened.

A man entered.

He was tall, dressed in a crisp black shirt, sleeves rolled up, hair slightly messy as if he had been running his hands through it in worry. His eyes—warm hazel—landed on her with relief flooding them.

“You’re awake,” he said softly.

Katherine stared at him, eyes cold, studying every detail.

She knew this face from the book’s descriptions.

Gentle. Honest. Too kind for the world he lived in.

But in person… he was even more striking.

Still, she showed no recognition.

“Who are you?” she asked flatly.

James blinked, taken aback. “I—I’m James. James Walker. I found you last night.”

Katherine didn’t respond.

James stepped forward cautiously, raising both hands as if approaching a frightened animal.

“You were unconscious on the road. I thought you were hurt, so I brought you here. My doctor checked you—he said you were exhausted, but not injured.”

Katherine’s eyes remained sharp.

Her voice held no warmth.

“So you brought a stranger to your home?” she asked. “Are you always this careless?”

James flushed, embarrassed but honest.

“I didn’t want the media to swarm you,” he said. “Hospitals aren’t safe for people found on roads. I… wanted to help.”

He meant it.

She could hear it in his voice.

For a moment, silence settled between them.

Then Katherine tilted her head slightly.

“Katherine,” she said at last.

James blinked. “Your name?”

“Yes. Katherine.” Her tone softened just barely. “And thank you… for helping me.”

James let out a breath he didn’t know he was holding and smiled—soft, relieved, genuine.

“You’re safe now.”

Katherine didn’t smile back, but she looked at him for a long moment.

*Safe.*

A word she had never trusted.

James stood near the edge of the room, watching Katherine carefully.

She sat with her back straight, hands resting calmly on her lap, eyes expressionless.

He cleared his throat softly.

“Um… I know this might be sudden but—should I call your family?” he asked gently. “They must be worried.”

Katherine didn’t even blink.

“I don’t have a family.”

Her voice was flat.

Matter-of-fact.

Not tragic—just truth.

James’ brows furrowed. “…Oh.”

He shifted, unsure if he was prying.

“O-Okay,” he continued carefully, “then should I take you home? Wherever you live? Your apartment or—”

Katherine cut him off with a cold, steady gaze.

“I don’t have a home either.”

The silence that followed was sharp.

James’s breath caught, his chest tightening at her tone. There was no sadness in her words, no vulnerability—just emptiness, quietly spoken.

He had never met someone who said such heartbreaking things with such a calm face.

“What do you mean…?” he whispered.

“Exactly what I said.” Katherine’s expression didn’t change. “I have neither family nor a home to return to.”

It wasn’t a lie.

Not in this world.

Her original home, her real life—gone. She had no identity here, no existence on any record, no past that belonged to this world.

She was truly homeless.

James swallowed hard. He stared at her, shock flickering across his face before melting into something softer… heartbreakingly gentle.

He looked at her as if he were seeing a little girl left outside in the rain.

“I… I’m so sorry,” he whispered, voice barely audible.

Katherine didn’t react.

Didn’t look away.

Didn’t offer an explanation.

She simply stated it like a fact.

A truth she had long accepted.

But James—

He was troubled. Deeply. His eyes softened, sadness pooling in them the more he studied her calm, untouched expression.

So that’s why she looks like that…

He thought.

So emotionless. So guarded. She must’ve gone through so much.

He took a small step closer, careful not to invade her space.

“You don’t have to face things alone,” he said quietly. “At least… not right now.”

Katherine tilted her head slightly, observing him.

He meant it.

Every word.

He pitied her.

She didn’t like pity—she had never needed it.

But coming from James Walker… it didn’t sting.

His kindness was too gentle to feel insulting.

Still, she kept her voice cold.

“I don’t need sympathy,” she said simply.

“I know,” James replied with a faint, earnest smile.

A normal person would have been trembling. Crying. Confused.

But this woman…

She was steady, composed, unshaken.

“Then… where were you going last night?” he asked softly.

“Nowhere,” she replied.

“And before that?”

“Nowhere.”

Her blank tone made a chill run down his spine—and yet, instead of fear, he felt a strong urge to protect her.

It didn’t make sense.

James took a small step closer, lowering his voice as if not to disturb her calm façade.

“Katherine… you don’t have to be alone now. I mean—at least let me help you. Until you’re better.” He hesitated. “You can stay here for a while, if you’d like. This place is safe.”

Katherine’s eyes finally flicked up to study him.

So gentle.

So soft-hearted.

No wonder Sophia used him.

“You’ve already helped me enough,” she said. “I won’t stay long.”

James shook his head quickly.

“You can stay as long as you need,” he insisted, cheeks flushing slightly at the boldness of his own words. “I—I mean it.”

Katherine held his gaze for a moment.

Then she nodded once, slowly.

“Fine.”

James’ shoulders relaxed in visible relief.

He didn’t know who she was.

He didn’t know where she came from.

All he knew was he couldn’t let her walk back into danger.
