I stared at the photograph for a long time.

The loose shirt Tham Kha Ngon was wearing belonged to Co Vong Nien.

I recognized it immediately.

I had bought it for him on his birthday last year.

And the crystal glass in her hand—

the one engraved with SXY—

was mine.

There were only two in the world.

He had ordered them himself.

One with his initials.

One with mine.

Back then, he had held both glasses up beneath the kitchen light and smiled.

“One for you. One for me. Nobody else uses them.”

I saved the photograph.

Then I blocked his number.

That night, I packed.

Not dramatically.

No broken photographs.

No clothes thrown across the floor.

I folded everything carefully.

At two in the morning, another notification appeared.

One of our mutual friends had posted a video.

Tham Kha Ngon was sitting on the kitchen counter while Co Vong Nien cooked noodles.

Someone behind the camera laughed.

“Brother Gu, aren’t you afraid Tinh Yen will be angry?”

He did not turn around.

“She gets angry quickly, but she also forgives quickly.”

Everyone laughed.

Then Tham Kha Ngon asked sweetly:

“What if she really breaks up with you?”

Co Vong Nien finally looked toward the camera.

He smiled.

“She won’t.”

Two words.

That was all.

Not because he trusted our love.

Because he trusted my tolerance.

I turned off the phone.

At seven the next morning, I left the apartment.

I took only what belonged to me.

Before closing the door, I placed my key on the dining table.

Beside it was the second wine glass.

His.

Mine was already in the trash.

I left no letter.

I had already said everything.

Once you leave, don’t come back again.

He left anyway.

At eleven, Co Vong Nien finally returned.

I know because he called me from six different numbers.

Then messages began arriving through friends.

Tinh Yen, where are you?

Stop joking.

Come home.

Then:

I was only helping Kha Ngon because she was drunk.

And finally:

You know I don’t like women who use breakups to threaten me.

I read that last message.

Then blocked the seventh number.

By afternoon, he went to my office.

My colleague called.

“Your boyfriend is downstairs.”

“Ex-boyfriend.”

There was silence.

“Should I send him up?”

“No.”

“What if he refuses to leave?”

“Security exists for a reason.”

Apparently that was when Co Vong Nien first understood I was serious.

He waited outside my building for almost three hours.

I left through the underground parking garage.

For the next week, I did not see him.

But I saw Tham Kha Ngon.

She posted constantly.

Flowers on her desk.

Coffee delivered by someone whose hand looked very much like his.

A photograph inside Co Vong Nien’s car.

Then a sentence:

Some people leave because they were never meant to stay.

I almost admired her confidence.

She believed she had won.

She did not understand that I had stopped playing.

Three days later, something happened at Co Vong Nien’s company.

A confidential pricing proposal appeared in a competitor’s presentation.

The numbers were nearly identical.

Only four people had access to the original file.

Co Vong Nien.

The finance director.

The project manager.

And his personal assistant.

Tham Kha Ngon.

He called me that night.

I didn’t answer.

Then he sent one sentence:

Did you take anything from my laptop before leaving?

I stared at it.

Then laughed.

So that was how much he trusted me now.

Enough to accuse me before questioning the woman he had spent weeks defending.

I replied once.

No. Ask the person you trust completely.

Then I blocked him again.

The investigation took four days.

The answer was embarrassingly simple.

Tham Kha Ngon had forwarded internal files to her personal email several times.

Not because she was some criminal mastermind.

Her former boyfriend worked for a competing firm.

She had been sending him documents in exchange for information and favors.

Most of it was small.

Schedules.

Client preferences.

Pricing ranges.

But the latest file was serious.

Co Vong Nien refused to believe it at first.

Exactly as I expected.

He reportedly said:

“There must be another explanation.”

The IT director showed him the access logs.

Still he asked:

“Could someone have used her computer?”

Then they showed him security footage.

Tham Kha Ngon entering the office alone after midnight.

Finally, they recovered messages.

Her former boyfriend had written:

Does Gu really trust you this much?

She replied:

More than his girlfriend.

Another message followed.

That woman is annoying. Once she’s gone, everything will be easier.

When Co Vong Nien saw those words, he called me again.

This time from his mother’s phone.

I answered because I thought something had happened to her.

Instead I heard his voice.

“Tinh Yen.”

I immediately tried to hang up.

“Wait!”

His voice was hoarse.

“Kha Ngon was lying.”

I closed my eyes.

“So?”

“She leaked company information.”

“That sounds like a company problem.”

“She was using me.”

I almost laughed.

“And you’re telling me because?”

Silence.

Then:

“I was wrong about her.”

I leaned against the window.

“That still doesn’t make you right about me.”

He stopped breathing.

For years, Co Vong Nien had believed every problem between us ended the moment the other woman was proven wrong.

It didn’t.

Tham Kha Ngon could be manipulative.

She could lie.

She could provoke me deliberately.

None of that changed what he chose to do.

I continued:

“She spilled wine on me and looked directly into my eyes while doing it.”

“I know.”

“She humiliated me in front of your friends.”

“I know.”

“She cried once, and you almost stayed behind with her.”

“I…”

“You came home with me only because everyone was watching.”

He went silent.

“And when she cried again?”

I smiled faintly.

“You left.”

“Tinh Yen, I thought she was emotionally unstable.”

“And I told you that if you walked out, we were finished.”

“You were angry.”

“No.”

My voice became colder.

“You decided I was angry because that made my words easier to ignore.”

That hurt him.

I could hear it.

Then he whispered:

“The glass…”

My fingers tightened.

“You saw the photo?”

“Yes.”

“She used your glass without asking.”

I laughed.

Finally.

Really laughed.

“That is still your excuse?”

“I didn’t give it to her.”

“You brought her into our home.”

Silence.

That was the truth.

Our apartment.

Our kitchen.

My glass.

His shirt.

He had allowed another woman into the space he always told me was ours.

Then expected me to believe the boundaries still existed because he had never formally announced crossing them.

“I’m sorry.”

I said nothing.

“I’ll fire her.”

“She should be handled according to company policy.”

“I’ll never see her again.”

“That is your decision.”

“Then come home.”

“No.”

His voice cracked.

“I’ve fixed it.”

That sentence almost made me sad.

He genuinely believed removing Tham Kha Ngon would restore what existed before.

But she had not broken us alone.

She had simply found the crack he kept insisting wasn’t there.

Two weeks later, he came to my parents’ house.

My father did not stop him.

I agreed to speak outside.

Co Vong Nien looked exhausted.

“I haven’t slept properly.”

I said nothing.

“I terminated Kha Ngon.”

I nodded.

“The company is pursuing the data breach separately.”

“Good.”

His eyes searched mine.

“Can we talk about us now?”

“We are talking.”

He took a step closer.

“I was stupid.”

“Yes.”

“I thought you were jealous.”

“I was.”

He froze.

I continued:

“I was jealous.”

“I was hurt.”

“I hated watching another woman take things that should have had boundaries around them.”

His eyes reddened.

“Then you still cared.”

“I did.”

Hope appeared too quickly.

So I finished:

“But caring doesn’t mean staying.”

His face fell.

I looked at him.

“The night I asked you not to leave, I gave you a choice.”

“You thought I was testing you.”

“I wasn’t.”

“You thought I would forgive you.”

“You were wrong.”

He whispered:

“Five years, Tinh Yen.”

“I know.”

“You can really end five years because I went back to a party?”

“No.”

I shook my head.

“I ended five years because you kept teaching me that whenever another woman needed your attention, I was expected to understand.”

He looked down.

“I never loved her.”

“That’s not the defense you think it is.”

He looked up.

I continued:

“If you had loved her, at least your choices would have had an explanation.”

“But you risked us for a woman you claim meant nothing.”

That silenced him completely.

Months passed.

Co Vong Nien tried several times to reconcile.

Flowers.

Letters.

Apologies.

I returned everything except one letter.

In it he wrote:

I thought security meant knowing you would never leave. I didn’t understand that security should have meant making sure you never had a reason to.

I kept that sentence.

Not because I intended to return.

Because for once, he had understood.

A year later, I met several old friends for dinner.

Someone mentioned Tham Kha Ngon.

She had left the city after the investigation.

Nobody knew much else.

Then someone cautiously asked:

“And Co Vong Nien?”

I smiled.

“What about him?”

“He’s still single.”

I took a sip of tea.

“That sounds like his business.”

My friend stared at me.

“You really don’t regret it?”

I thought about the red wine.

The fake tears.

His coat around my shoulders.

His phone constantly lighting up.

The apartment door closing behind him after I told him exactly what leaving would mean.

Then that photograph.

A woman in his shirt.

Holding my glass.

I shook my head.

“No.”

Because the relationship did not end when Tham Kha Ngon touched something that belonged to me.

It ended when Co Vong Nien decided I would always remain available no matter how often he made me feel replaceable.

Months later, I bought another pair of wine glasses.

Nothing custom-made.

Nothing engraved.

Just two simple glasses.

A friend visiting my apartment laughed.

“Why two if you live alone?”

I looked at them.

“One for me.”

“And the second?”

“For whoever deserves to be invited.”

That was the difference.

Co Vong Nien once had a permanent place in my life.

He believed that place could never be taken away.

Tham Kha Ngon thought holding my glass meant she had won it.

Neither understood.

I was never the prize they were competing over.

My trust was.

And once Co Vong Nien handed that away—

there was nothing left for him to come home to.
