Prologue

Rain slammed against Shanghai that night.

Jiang Meilin stood outside the hospital, gripping a medical bill like it was a punishment. Her mother’s breath was fading. Surgery was the only hope.

But hope cost money she didn’t have.

She had no one left to call… until a black Bentley rolled to a slow, sharp stop in front of her.

The door opened.

Lu Shen stepped out—tall, crisp suit, cold aura, the kind of man people avoided.

“I can save your mother,” he said quietly. “But I need something in return.”

Her voice trembled. “What do you want?”

“A wife.”

No warmth. No emotion. Only a deal.

“Marry me, Jiang Meilin,” he said, “and your mother lives.”

She nodded with a breaking heart.

That night sealed her fate…

And unknowingly sealed his, too.

CHAPTER 1 — The Contract Night

Rain beat down on Shanghai like the sky was angry.

Jiang Meilin ran through the hospital hallway with her breath breaking in her chest. Her shoes were soaked. Her hair stuck to her face. Her hands shook as she clutched the newest bill the doctor had given her — a bill she couldn’t pay no matter how many times she counted the money in her pocket.

Her mother lay inside Room 403, pale, weak, and hooked to tubes that hummed like sleepy machines. Meilin stood there for a long moment, watching the slow rise and fall of her mother’s chest.

“Mom… please hold on,” she whispered.

Her mother didn’t open her eyes.

Meilin bit down a sob and stepped out, letting the door close behind her with a soft click. She walked down the dim hospital steps and found herself outside under the roof, staring at the rain that blurred the whole world. She hugged the thin folder of bills to her chest as if holding it tight would magically fix everything.

She had tried everything.

Borrowing money.

Part-time jobs.

Extra shifts.

Selling her few things.

Begging relatives who looked at her like she was trash.

Nothing worked. The surgery had to be done soon. The doctor said they had only a few days before it was too late.

Her hands trembled so badly that the papers slipped and started scattering on the wet floor.

“Great,” she whispered, crouching down to pick them up, her fingers shaking as raindrops splattered over the ink.

She blinked hard to stop tears from coming, but they came anyway. She felt tiny in that moment — a single girl fighting the entire world alone.

Then—

A black Bentley ghosted into view, moving slow, smooth, and silent. The kind of car she had only seen in magazines. It rolled to a stop in front of her. The windows were tinted so dark her own reflection stared back at her.

She froze.

The back door opened with a quiet click.

A man stepped out.

Tall.

Sharp.

Dark suit.

Cold eyes that didn’t shake even under the storm.

She didn’t know him personally, but everyone in Shanghai knew his face. They knew his name.

Lu Shen.

The youngest billionaire in the city.

Powerful, emotionless, and dangerous if crossed.

He didn’t look at the rain. He didn’t look at the world.

He looked only at her.

For a moment, Meilin wondered if she was dreaming. Why would a man like him stop for a girl like her? Why would he even know her name?

Before she could run, speak, or breathe, his voice cut through the rain — low, steady, cold, like a blade wrapped in silk.

“Jiang Meilin.”

Her breath caught.

He did know her name.

She took a shaky step back. “I… I don’t understand. Did someone send you?”

“No,” he said.

His expression didn’t change, not even by a hair. His gaze was calm but too sharp. Too knowing. Like he saw straight through her clothes, her skin, her heart, her fears.

“I can save your mother.”

The words hit her harder than the storm.

Meilin’s fingers dug into the soaked papers. “W-What?”

“I can pay for the surgery. All of it. The treatment. The recovery. Everything she needs.”

Her throat closed.

No one gives that kind of help for free.

No one hands out millions because they feel kind.

Especially not a man like this.

Her voice trembled. “Why… why would you help me?”

Lu Shen stepped closer. He didn’t smell of rain. He smelled clean, sharp, and expensive. Like cold metal and fresh ink.

His eyes never left hers.

“Because I need something,” he said.

Meilin swallowed hard. “What do you want?”

“A wife.”

She felt the air punch out of her lungs.

A wife.

A wife?

Before she could speak, he continued, calm as ice:

“Not love. Not romance. Not emotions. I don’t want any of that. I only need the title. I need a woman who can stand beside me for a period of time. Quiet. Simple. Clean background. No scandals. You fit.”

She felt like the ground tilted.

Her voice barely came out. “But you don’t even know me…”

“I know enough.”

His eyes lowered to the crumpled medical bills in her shaking hands.

“You’re desperate,” he said softly.

“And you need me.”

The strikes of rain softened as if the world was listening.

He extended a small black folder — thin, smooth, and carrying a cold weight that made her skin prickle.

A contract.

A marriage contract.

“If you agree,” he said slowly, “your mother lives.”

Meilin stared at the folder like it was poison and salvation at the same time.

Some part of her wanted to run.

Another part reminded her of her mother’s fading heartbeat.

She opened the folder with numb fingers.

Rules.

Conditions.

Boundaries.

No touching.

No demands.

No falling in love.

Her name line was empty, waiting.

Her chest rose and fell as she stared at the space where her signature would go.

Lu Shen watched her with unreadable eyes. “Decide.”

She looked at the hospital windows behind her.

Her mother.

Her only family.

Her only reason to fight.

Then she looked at him — this cold, strange man who was offering her a lifeline in the most twisted form.

Her voice cracked.

“I… I’ll do it.”

He didn’t smile.

He didn’t soften.

He simply handed her a pen.

The rain finally stopped as she pressed the tip to the paper and signed her name.

Jiang Meilin.

When she lifted her head, Lu Shen was still staring at her. But something flickered in his eyes — fast, thin, gone before she could understand it.

“Good,” he said quietly. “Get in the car.”

Just like that, her old life ended.

And a new one — built on ice, secrets, and a billionaire’s cold shadow — began.

CHAPTER 2 — Entering the Cold Man’s World

The Bentley door closed behind Jiang Meilin with a soft, heavy thud that made her heart jump. The inside of the car felt too clean, too silent, too expensive for someone like her. She sat stiffly, clutching her damp bag, aware of every breath she took.

Lu Shen slid in beside her. He didn’t look at her. He didn’t look at anything. He simply picked up a tablet, tapped the screen once, and the car began to move.

The driver didn’t say a word. No one did.

Only the rain whispered against the windows.

Meilin sat with her hands folded tight on her lap, her fingers trembling. Her wet hair dripped onto the leather seat. She tried to brush it away, but it kept falling forward.

She felt messy. Small. Out of place.

Lu Shen didn’t look messy at all. His suit was perfect. His jawline sharp. His posture is calm. It was like the storm outside couldn’t touch him.

She closed her eyes for a moment and whispered inside her mind:

What have I done…?

But then she saw her mother’s face in her memory, pale and fading, and she forced herself to breathe.

This was for her mother.

Only her mother.

Nothing else.

Still, the silence in the car pressed against her chest until she couldn’t hold it anymore.

“Um… Mr. Lu?” she whispered.

He didn’t look at her. “Speak.”

She swallowed. “Is this… really okay? I mean… marrying someone you don’t know?”

He turned one page on his tablet. “I don’t need to know you. I only need you to follow the contract.”

Her heart dropped a little at his tone — cold, flat, like she was paperwork and not a person.

She lowered her gaze. “I understand.”

“You will move into my penthouse tonight,” he said without hesitation.

Her head shot up. “T-Tonight?”

“Yes.”

“Oh…” Her fingers twisted around her bag strap.

She wasn’t ready.

Her life was in bags at the small apartment she rented.

She didn’t have clothes for this man’s world.

Or shoes.

Or anything.

He didn’t care.

“Is that a problem?” he asked, finally lifting his eyes from the tablet.

Those eyes hit her like a direct punch — sharp, cold, empty, as if emotions were something he threw away years ago.

“N-No,” she whispered. “It’s not a problem.”

She swallowed her fear like a bitter pill.

—

The car cut through Shanghai’s glowing night, heading toward the Bund. The buildings rose like giants, their lights mixing with the last drops of rain. Meilin stared at the city she knew yet didn’t recognize anymore. It felt like she had stepped into a different universe — one she didn’t belong in.

“You will sign a second document once we arrive,” Lu Shen said, his voice steady.

“A second… document?”

“Yes. The marriage registration will be handled tomorrow morning. The document tonight is for internal use.”

She didn’t dare ask what “internal use” meant. She wasn’t sure she wanted to know.

Instead, she folded her hands tighter. “Okay.”

He gave no reply.

—

The Bentley turned through a secured private gate, guarded by men in black suits. They bowed as the car passed, their faces serious, respectful.

Meilin stared.

Who was this man she had agreed to marry?

The car stopped inside an underground garage so clean it looked like a museum. Luxury cars lined the sides — black, silver, sleek, shining like quiet predators.

The door opened for her automatically.

She stepped out, her feet soft on the polished floor.

Lu Shen’s voice came from behind her. “Follow me.”

He didn’t wait.

She hurried after him, her steps small, her heart loud.

They entered a private elevator. The doors closed. Silence filled the space again. He pressed the top button.

Penthouse.

As the elevator rose, her ears popped. She could feel his presence beside her like cold air brushing against her skin.

She kept her eyes on the floor.

A small part of her wondered what he thought of her — this soaked, shaking girl who signed his contract.

But his expression didn’t show a single thought.

The elevator stopped with a gentle ding.

The doors opened.

Meilin’s breath caught in her throat.

The penthouse felt unreal.

Glass walls.

Warm lights.

Marble floors.

Tall bookshelves.

A skyline view of Shanghai that looked like a painting.

And not a single thing looked touched. Everything was perfect, still, and cold.

“This is where you’ll stay,” he said as he walked inside.

She followed, careful not to step on anything expensive.

“Your room is on the left,” he continued. “Mine is at the end of the hall. Do not enter my room unless I allow it.”

“Okay,” she whispered.

“There are rules. You will read them.”

He handed her another black folder — thicker than the first.

Rules.

Pages and pages of rules.

Her hands shook as she opened it.

No entering his study.

No talking during his meetings.

No touching him.

No asking personal questions.

No disturbing his rest.

No interfering with his work.

No acting as his actual wife in public unless he signals it.

She blinked.

This wasn’t a marriage.

This was a cage with expensive walls.

She lowered the papers. “I… understand.”

“Good.” His eyes flicked over her wet clothes. “A maid will bring you something to wear. Do not walk around looking like that. You will ruin the floor.”

Her cheeks heated. “Sorry…”

He gave no reaction, no comfort, no sign of kindness. He simply walked toward his study and stopped at the door.

“Your mother’s surgery will be arranged first thing in the morning,” he said without turning around.

Her heart stilled.

“T-Thank you,” she whispered, tears filling her eyes.

He paused.

For a second, she thought he might say something warmer.

But he didn’t.

“All that matters is that you follow the contract,” he said, then entered the study and closed the door behind him.

The soft click echoed like a door shutting on her old life.

Meilin stood alone in the silent penthouse, holding a folder of rules thicker than her courage.

Her hands trembled.

Her chest tightened.

Her eyes stung.

But she wiped her tears quickly.

For her mother.

For her promise.

For survival.

She walked to the room he said was hers — a soft, simple space with a bed, a closet, a private bathroom, and nothing else.

She sat on the edge of the bed.

For the first time since signing the contract, she whispered the truth she had been afraid to say:

“I’m scared…”

But no one answered.

Only the quiet hum of the penthouse lights kept her company.

In another room, behind a locked door, Lu Shen stood by his window, watching the city with unreadable eyes.

He touched the marriage contract on his desk — her fresh signature still drying.

For a moment, only a moment, something flickered across his face.

Something sharp.

Something dark.

Something like a memory.

Then it was gone.

He closed the file and said to himself:

“Let’s see how long you last, Jiang Meilin.”

CHAPTER 3 — First Dawn in a Stranger’s Home

Jiang Meilin didn’t sleep.

Not even for a second.

The room was too soft, too warm, too clean. The sheets smelled like new cotton and quiet money. The pillows were huge and fluffy, not the thin, flat ones she used back at her tiny apartment. Everything around her felt like a dream she couldn’t enter — like she was sitting inside someone else’s life.

Every few minutes, she looked at the clock on the wall.

2:15 a.m.

2:37 a.m.

3:20 a.m.

3:59 a.m.

Her heartbeat never slowed.

Her breath never settled.

She kept thinking: Did I really marry that man? Did I really sign my life to him? Did I… move into a billionaire’s home?

It felt unreal.

Wrong.

Heavy.

But then she’d remember her mother — unconscious in Room 403 — and she would breathe again. That was the reason. The only reason.

She hugged her knees, staring at the floor.

Her phone buzzed at 4:17 a.m.

A message from the hospital.

Your mother’s surgery is scheduled for 10 a.m.

Full payment received.

Prep begins at 6 a.m.

Her breath caught.

He really paid.

He really did it.

For a moment, a tear rolled down her cheek. Not from sadness. From relief so sharp, it hurt.

She wiped it fast.

Crying felt dangerous in that house — like the walls would judge her.

—

At 6 a.m., a soft knock sounded on her door.

“Madam Lu,” a woman’s voice said gently. “Are you awake?”

Madam Lu.

The words hit her like ice.

She opened the door slowly.

A maid stood there — neat hair bun, soft smile, wearing a simple black-and-white uniform. She bowed slightly.

“Good morning. I’m Aunt Zhang,” the maid said. “Mr. Lu asked me to prepare your breakfast and show you around.”

Meilin waved her hands quickly. “O-Oh! No, please, don’t call me Madam Lu. I’m not— I mean— this marriage is not—”

Aunt Zhang smiled kindly. “Rules are rules. If the master says you’re Madam Lu, then that’s what you are.”

Meilin wanted to hide under the bed.

The maid stepped back a little. “You should freshen up. Breakfast will be ready soon.”

She nodded awkwardly and closed the door, leaning her back against it.

Madam Lu.

It was a title she never asked for.

A title she wore like an oversized coat that didn’t belong to her.

She washed quickly, brushed her hair, and changed into the soft beige dress the maid left on the bed earlier.

It was simple but expensive. Smooth fabric. Perfect fit.

She looked at herself in the mirror.

Who was this girl?

Surely not her.

—

The penthouse looked different in daylight.

Warmer. Brighter. But still cold in its bones.

Aunt Zhang led her to the dining area. The table was long enough to seat twenty people. The plates were arranged like a photoshoot. The air smelled like warm bread and fried eggs.

“Sit, dear,” Aunt Zhang said softly.

Meilin sat, feeling small again.

The food looked too pretty to touch.

She lifted her chopsticks carefully, wondering if eating the wrong way would break some secret billionaire rule.

Then she heard footsteps.

Her fingers froze.

The footsteps were sharp, steady, and cold — the kind that came from someone who didn’t need to hurry to be respected.

Lu Shen.

He walked in wearing a crisp white shirt, and sleeves rolled to his elbows. His hair was still damp, like he just came from the shower. He looked too clean, too sharp, too… far from her world.

His eyes flicked toward her seat.

“You’re awake,” he said simply.

She stood up too fast. “G-Good morning.”

“Sit.” He took the head seat.

She sat instantly, like a student caught doing something wrong.

Aunt Zhang poured him coffee and stepped back.

Lu Shen didn’t touch the food immediately. He scanned her from head to toe in a way that wasn’t rude but also wasn’t warm.

“You slept?”

She shook her head. “Not really.”

“Why?”

“I’m… not used to this place.”

“That will change.”

The confidence in his voice made her stomach twist. He spoke like someone who always got what he wanted, always controlled what changed, and always controlled people.

She picked up her chopsticks again.

Her hand shook.

He noticed.

His eyes narrowed. “Are you nervous?”

She bit her lip. “I just don’t want to break any of your rules.”

“You already broke one,” he said calmly.

Her soul left her body.

Her voice cracked. “I—I did?”

“Yes.”

He took a sip of coffee.

She sat frozen, waiting for the punishment she didn’t even know yet.

He set his cup down gently.

“You called yourself ‘not Madam Lu.’”

Her heart dropped.

“I— I’m sorry— I didn’t mean— I just—”

He didn’t raise his voice.

He didn’t frown.

He didn’t show anger.

But his tone turned colder than last night’s rain.

“You signed the contract. You wear the name.”

She lowered her eyes. “Okay… I understand.”

He returned to his breakfast as if nothing had happened.

Meilin tried to eat, but her hands still trembled so much she almost dropped her chopsticks. She pressed them to the table to steady herself.

After a long moment, his voice broke the silence again.

“You will go to the hospital today.”

She lifted her head. “Yes.”

“A driver will take you. A bodyguard will follow.”

Her eyes widened. “A bodyguard?”

“Did you think you would walk around Shanghai alone?” His eyes didn’t soften. “You carry my name now.”

She swallowed.

“I… I didn’t think about that.”

“You should.”

His gaze stayed on her, unreadable.

“You look like someone who forgets she is no longer invisible.”

Invisible.

The word cut deeper than it should.

Because it was true.

She had always been invisible.

Always unnoticed.

Always surviving quietly.

Now, suddenly, her life was a spotlight she didn’t ask for.

He stood up, straightening his cuffs.

“I have meetings. Read the rules today. Don’t cause trouble.”

She nodded quickly.

Then he paused in the doorway.

His voice dropped lower.

“And Jiang Meilin… eat.”

She blinked. “I… am eating.”

“You’ve touched nothing.”

Her cheeks burned.

He didn’t wait for her excuse.

He didn’t ask anything else.

He simply walked out, leaving the room colder than before.

—

When she finally forced herself to eat, Aunt Zhang approached softly.

“Don’t worry,” the maid whispered with a warm smile. “Master Lu looks cold, but he always means what he promises. Your mother will be safe.”

Meilin nodded, her eyes stinging.

“I hope so…”

“Eat well, dear. You’ll need your strength.”

For the first time since entering this cold world, someone touched her shoulder gently.

It made her chest ache.

—

After breakfast, the driver took her to the hospital.

She sat in the backseat, staring out the window. The city moved fast outside, but inside her chest, everything felt slow, heavy, and uncertain.

When she reached the hospital, nurses rushed around preparing for her mother’s surgery. The doctors called her in to sign more forms. She signed everything with trembling hands.

At 9:57 a.m., the surgery team came to wheel her mother out.

Meilin walked beside the stretcher, holding her mother's frail hand.

“Mom,” she whispered softly, leaning close. “Please come back to me. Please wake up. I’m right here.”

Her mother didn’t respond.

The nurse touched her arm. “We’ll take care of her.”

Meilin nodded with watery eyes.

She watched them push her mother through the doors.

The doors closed.

And her heart went quiet.

Her legs gave out, and she slid down the wall to the cold floor, hugging her knees as silent tears rolled down her cheeks.

This was the moment everything depended on.

This surgery.

This deal.

This cold marriage she couldn’t escape.

She wiped her face slowly.

She needed to be strong.

For her mother.

For the life she had stepped into.

For the future, she wasn’t sure she wanted.

Suddenly, her phone buzzed.

A message.

From: Unknown Number

Her breath paused as she opened it.

“You left the penthouse without eating enough.

You need to take care of yourself if you want to last here.”

Her heart stopped.

It was him.

Lu Shen.

Watching.

Noticing.

Tracking her movements like a silent shadow.

Another message popped up.

“Update me once the surgery begins.”

She stared at the screen.

Cold man.

Cold words.

Cold marriage.

But…

He texted her.

And for a tiny second, that coldness didn’t feel as icy.

She wiped her tears and typed back with shaky fingers.

“The surgery just started.”

Three dots appeared on the screen.

Typing.

Then—

“Good. Don’t fall apart.”

Meilin closed her eyes.

She wouldn’t fall apart.

Not today.

Not now.

Not in this new life she had stepped into.

She stood up slowly, wiped her face, and took a long breath.

Today was the start of everything.

And she had no idea that this day would also be the first crack in the cold billionaire’s heart.
