Three hours before my flight, Nora handed me a new folder.

“You can still change your mind.”

“I won’t.”

Inside were documents for the life I would begin in Europe.

Not a fake identity.

Nothing illegal.

Just a carefully prepared disappearance from the social world Adrian knew.

A new city.

A private research position.

No social media.

No contact with anyone connected to the Lu family.

To Adrian, Elena Jiang would simply vanish.

Before boarding, I mailed one final envelope.

Inside was my wedding ring.

Nothing else.

Adrian received it two days later.

By then, Clara had already found him.

I learned what happened months afterward.

She apparently arrived at his office crying.

“Adrian, Elena threatened me.”

He looked up.

“With what?”

Clara placed the British marriage certificate on his desk.

Adrian read it twice.

Then he called his legal team.

Within hours, they confirmed everything.

Clara had married Michael Li four years earlier.

She had never divorced him.

Worse, several payments Adrian sent for her “tuition” had been transferred into an account jointly controlled by Clara and Michael.

Adrian asked only one question.

“Why did you come back?”

Clara cried harder.

She said the marriage had been a mistake.

She said Michael had betrayed her.

She said Adrian had always been the person she truly loved.

But Adrian interrupted.

“Did Elena know?”

Clara went silent.

That silence told him everything.

For the first time, Adrian understood something that should have been obvious.

I had possessed enough evidence to destroy Clara before our divorce.

Yet I hadn’t used it to keep him.

I had simply left.

That night, Adrian called me.

Disconnected.

He called Nora.

She said she didn’t know where I was.

He went to my old apartment.

Empty.

Then he discovered something worse.

The hotel near the airport reported that I had checked out.

After that, there was no public trace of me.

Weeks became months.

Months became years.

And Adrian searched.

Quietly at first.

Then obsessively.

Meanwhile, I rebuilt my life in Switzerland.

Before marrying Adrian, I had studied biomedical engineering.

I abandoned my doctorate after his grandmother became ill because someone needed to remain beside her.

Nobody in the Lu family remembered that sacrifice.

I did.

So I returned to university.

Four years later, I completed the research I had once abandoned.

Six years later, our laboratory developed a specialized neural-interface system designed to help patients with severe motor impairment communicate.

The technology attracted international attention.

But my name rarely appeared publicly.

That was intentional.

I had learned that peace was more valuable than recognition.

Then, in the seventh year after my divorce, Nora called.

“Elena.”

Her tone immediately worried me.

“What happened?”

“It’s Adrian.”

I remained silent.

“He collapsed during a board meeting.”

I closed my eyes.

“And?”

“A neurological disorder.”

“Is it serious?”

“Yes.”

There was a pause.

“He can understand everything around him, but his ability to communicate is deteriorating.”

I sat beside my laboratory window.

Seven years.

And suddenly the favor I had requested on our divorce day returned to my mind.

Not because Adrian was sick.

Because two weeks earlier, my research team had received an invitation from Beijing.

The government wanted our neural-interface program to participate in a major national medical initiative.

There was one obstacle.

The project required access to a private neurological database accumulated over decades.

The database belonged to the Lu Medical Foundation.

Adrian controlled it.

That was the door.

The one I had known might someday become important.

I returned to Beijing without telling him.

The city looked familiar and foreign at the same time.

At the hospital, Adrian’s assistant nearly dropped his tablet when he saw me.

“Mrs. Lu?”

“Ms. Jiang.”

He stared.

“You’re alive.”

“I never said otherwise.”

When I entered Adrian’s room, I barely recognized him.

He had lost weight.

His face was pale.

But his eyes were still the same.

Cold.

Sharp.

Until they saw me.

Then everything changed.

His fingers moved slightly against the blanket.

“Elena…”

The word came out broken.

I stopped several feet from the bed.

Adrian stared at me as though seven years had disappeared.

His eyes reddened.

He tried to sit up.

I didn’t move closer.

“Don’t.”

He stopped.

For several seconds, neither of us spoke.

Then he struggled to form another sentence.

“I… searched…”

“I know.”

His expression tightened.

“Why…”

Why did I leave?

Why did I disappear?

Why had I returned?

Perhaps all three.

I placed a document on the table.

“I came to collect my favor.”

Adrian stared at it.

Understanding slowly appeared in his eyes.

Seven years earlier, I had rejected five million yuan.

Now I wanted access to something potentially worth billions in research value.

“The Lu neurological database,” I said.

“Full research access for the national medical program.”

His assistant inhaled sharply.

Adrian didn’t hesitate.

He reached for the pen.

His hand trembled.

The signature took almost a minute.

But he signed.

No negotiation.

No conditions.

I picked up the document.

“Thank you.”

Then I turned away.

“Elena.”

I stopped.

His voice was barely audible.

“Stay.”

One word.

Seven years too late.

I looked back.

“I didn’t return for you.”

His eyes closed.

A tear slipped down his cheek.

I left.

Three months later, our clinical program began.

Adrian became one of its first patients.

Not because I selected him.

The medical board did.

The first time the interface worked, a sentence appeared on the monitor.

I expected something technical.

Instead, Adrian typed:

I AM SORRY.

I stared at the words.

Then another sentence appeared.

I SHOULD HAVE CHOSEN YOU.

I answered quietly.

“You did choose.”

His eyes met mine.

“You just didn’t choose me.”

He lowered his gaze.

But Adrian’s greatest regret hadn’t arrived yet.

During the database integration, my team discovered irregularities in several historical patient records.

One file caught my attention.

Seven years old.

Female patient.

Late seventies.

Lu family.

My heart stopped.

Adrian’s grandmother.

The woman whose final wish had supposedly forced Adrian to marry me.

I opened the archived notes.

Then I found an audio file recorded three days before her death.

Her voice filled my office.

Weak.

But unmistakable.

“Adrian still hasn’t told Elena the truth.”

I froze.

Another voice answered.

Adrian’s mother.

“He never should.”

His grandmother became angry.

“That girl deserves to know why he married her.”

My fingers went cold.

His mother replied:

“If Elena discovers what happened to her parents, she will never forgive this family.”

I stopped breathing.

My parents had died when I was seventeen.

A highway accident.

At least, that was what I had always believed.

The recording continued.

Adrian’s grandmother whispered:

“The Lu family owes that child far more than money.”

Then came the sentence that changed everything.

“Adrian married Elena because he knew the truth from the beginning.”

I immediately went to his hospital room.

Adrian saw my face and understood that something was wrong.

I placed the old patient file in front of him.

“What happened to my parents?”

His face went white.

“Answer me.”

His hand trembled toward the interface.

Slowly, words appeared on the monitor.

ELENA, I WANTED TO TELL YOU.

My heart began pounding.

“Tell me what?”

Another sentence appeared.

YOUR FATHER DIDN’T DIE IN AN ACCIDENT.

I felt the room tilt.

“Then how did he die?”

Adrian closed his eyes.

For several seconds, he refused to type.

Then his fingers moved.

Three words appeared.

MY FATHER KNEW.

I stared at him.

Adrian continued.

AND YOUR FATHER WAS TRYING TO EXPOSE HIM.

I stepped backward.

Suddenly, the five million yuan from our divorce felt insignificant.

The favor had opened the door I wanted.

But behind that door was something I had never expected.

The truth about why Adrian Lu had chosen me as his wife in the first place.
