Luc Xuyen gritted his teeth.

—Oanh Oanh and Chu Trach were only joking. Do you really have to ruin An An’s celebration?

I looked at him.

For one second, something inside me hurt.

Not because of Luc Oanh.

Not because of Chu Trach.

Because my husband had heard someone publicly question his son’s paternity—

and the first person he wanted to silence was me.

I slowly pulled my arm away.

—Luc Xuyen, listen carefully.

—Your sister just implied in front of more than a hundred guests that your wife cheated with your best friend and that your son isn’t yours.

I pointed at An An.

—And you’re worried about her embarrassment?

His expression stiffened.

Luc Oanh immediately began crying.

—Brother, forget it.

—It’s my fault.

—I shouldn’t have made that joke.

She wiped her eyes.

—Sister-in-law has always disliked me anyway.

There it was.

The familiar trick.

She attacked.

I resisted.

Then somehow she became the victim.

I picked up the microphone from the table.

—Good.

Everyone looked at me.

—Miss Luc has just admitted publicly that it was a joke.

Luc Oanh stopped crying.

I continued:

—The event team has recorded everything.

—Tomorrow my lawyer will prepare a written apology correcting the accusation.

—You and Mr. Chu will sign it.

Chu Trach’s face changed.

—Tham Vi, isn’t that excessive?

—No.

I smiled.

—What’s excessive is joking about a one-month-old child’s parentage.

Then I turned toward my husband.

—And since everyone is already so interested, let’s clear up the matter completely.

I opened my phone.

Three days earlier, our hospital had sent me the results of An An’s routine genetic screening.

Because Luc Xuyen had insisted on adding a private parentage test during my pregnancy.

He claimed his parents wanted “peace of mind.”

I had hated it.

But I agreed.

I had never opened the final electronic copy.

Until that morning.

I connected my phone to the hall screen.

Luc Xuyen suddenly caught my wrist.

—What are you doing?

I looked at him.

—Giving your family the certainty they wanted.

The document appeared on the giant screen.

PATERNITY PROBABILITY:

99.99%.

Luc Xuyen.

Biological father.

A murmur spread across the room.

Luc Oanh’s face became white.

I looked at Chu Trach.

—So now we know An An’s father.

Then I smiled.

—Would either of you like to explain why you invented the birthmark story?

Chu Trach immediately looked at Luc Oanh.

That glance betrayed them.

Luc Xuyen saw it too.

—Oanh Oanh?

She panicked.

—I just remembered wrong.

—Really?

I opened another message.

Before the party, one of Luc Oanh’s friends had sent me screenshots.

I hadn’t understood them at first.

Now they made perfect sense.

Luc Oanh:

“Tonight I’ll make her lose face in front of everyone.”

Chu Trach:

“Your brother will definitely defend you.”

Luc Oanh:

“Once they fight, Mom can push the divorce again.”

The hall exploded in whispers.

Luc Xuyen took my phone.

He read the screenshots again and again.

His face became terrifyingly calm.

—Divorce?

I looked at his mother.

Mrs. Luc immediately turned away.

That was enough.

I laughed.

—You didn’t know?

Luc Xuyen looked at me.

I answered:

—Your mother visited me three days after I gave birth.

She had placed a bank card beside my bed.

—Take the money and leave.

—Our Luc family needs a daughter-in-law who understands how to behave.

I refused.

Then she told me something even more interesting.

—Oanh Oanh says your temperament has become unbearable since pregnancy.

—Sooner or later Xuyen will get tired.

Apparently they had decided to help the process along.

Luc Oanh’s little “joke” wasn’t spontaneous.

It was supposed to create suspicion.

A public humiliation.

Then an argument between husband and wife.

And eventually—

a divorce.

Luc Xuyen looked at his mother.

—Is that true?

She immediately defended herself.

—I was thinking about you!

—Tham Vi has always been too strong.

—Since she married you, when has she ever respected our family properly?

I almost laughed.

Luc Xuyen interrupted her.

—Enough.

It was the first time I had ever heard him speak to his mother like that.

Then he turned toward Luc Oanh.

—And you.

His voice was low.

—Apologize.

Luc Oanh began crying again.

—Brother—

—Not to me.

He pointed toward me.

—To my wife.

Then toward the baby.

—And to my son.

I watched him.

Once, that would have been enough.

Once, I would have felt protected.

But protection arriving only after public proof was not the same as trust.

Luc Oanh finally apologized.

No kneeling.

No spectacle.

Just a clear statement into the same microphone she had used to humiliate me.

She admitted the accusation was false.

Chu Trach did the same.

I saved both recordings.

Then I walked to the nurse and took An An back into my arms.

Luc Xuyen followed me into the corridor.

—Tham Vi.

I stopped.

He looked exhausted.

—Why didn’t you tell me about my mother?

I stared at him.

—Would you have believed me?

His mouth opened.

Nothing came out.

I smiled sadly.

—Exactly.

He reached for my hand.

I moved away.

—You defended them before asking whether I was hurt.

—You told me not to ruin the party.

—You called what they did a joke.

His face tightened.

—I’m sorry.

—I know.

Then I said the words he clearly wasn’t expecting:

—I’m taking An An to my mother’s house for a while.

Panic appeared immediately.

—Are you leaving me?

—I don’t know yet.

That frightened him more than a yes.

For the next two months, Luc Xuyen did something he should have done much earlier.

He created boundaries.

His mother no longer had a key to our home.

Luc Oanh was not allowed near An An without me present.

Chu Trach disappeared from his circle completely.

And Luc Xuyen entered marriage counseling with me.

I didn’t return because he begged.

I returned only after I saw that his behavior had changed even when nobody was watching.

One evening, months later, he held An An while our son slept against his chest.

He looked at me.

—That day, when you challenged them in front of everyone… were you really not afraid?

I smiled.

—Of course I was.

—Then why did you do it?

I looked at our son.

—Because one day he’ll grow up.

—And if anyone tries to shame him for something he didn’t do, I want him to know his mother didn’t stand quietly and let them.

Luc Xuyen lowered his head.

The first-month celebration was supposed to welcome my son into the Luc family.

Instead, it revealed exactly what kind of family he had been born into.

A sister-in-law who called cruelty a joke.

A mother-in-law who called manipulation concern.

And a husband who nearly called my silence an obligation.

That day, the DNA report proved who An An’s father was.

But the harder question was whether that man deserved to remain my husband.

And for once—

I made him prove the answer with actions, not family excuses.
