Martin arrived on a Tuesday.

You remember that because it ruined everything.

At least, that’s what twelve-year-old you believed.

Your parents sat you down after dinner.

Your mom looked nervous.

Your dad kept glancing at her.

“We want you to meet someone,” your mom said.

And then Martin walked into your life.

Two months younger than you.

Small.

Quiet.

Holding a backpack that looked older than he was.

Brunette—at first—hair.

Big eyes.

The kind of kid adults immediately wanted to protect.

“Hi,” he said.

You didn’t answer.

You already hated him.

Not because of who he was.

Because of what he represented.

A replacement.

An addition nobody asked you about.

A stranger who was suddenly going to be family.

Your family.

Your room became “your boys’ room.”

Your parents became “our parents.”

Your home became “our home.”

Everything that had been yours suddenly had to be shared.

And Martin didn’t even seem happy about it.

Which somehow annoyed you more.

He was always polite.

Always thankful.

Always trying.

“Do you want the last cookie?”

“You can have the front seat.”

“I saved you a spot.”

It drove you insane.

Because you couldn’t tell if it was real.

Was he trying to gain your trust?

Trying to make your parents like him more?

Trying to show everyone he was the better son?

You didn’t know.

And that uncertainty made everything worse.

Months passed.

Then years.

And somehow Martin became the center of the house.

Your mom checked on him constantly.

Your dad never missed one of his school events.

If Martin got sick, the entire house stopped.

If you got sick, you got medicine and a “feel better.”

At least, that’s how it felt.

Maybe it wasn’t fair.

Maybe it wasn’t true.

But resentment rarely cares about facts.

One afternoon, your mom hung a new family picture in the hallway.

You stopped in front of it.

Mom.

Dad.

You.

Martin.

Smiling like he’d always belonged there.

“Looks nice, right?”

Martin’s voice came from behind you.

You turned.

He was holding a basket of laundry.

“Sure.”

Your answer came out colder than intended.

Martin’s smile faltered.

Just slightly.

“Did I do something?”

There it was.

The question he’d probably wanted to ask for years.

You could’ve told the truth.

Could’ve admitted you were jealous.

That every time your parents praised him, it felt like losing something.

Instead, you shrugged.

“No.”

A lie.

A terrible one.

Martin looked at you for a second.

Then nodded.

“Okay.”

And walked away.

No argument.

No guilt trip.

Nothing.

Just quiet acceptance.

Which somehow made you feel worse.

Because after all these years, Martin had never once tried to take your place.

He never acted like the chosen one.

Never bragged about being adopted.

Never rubbed anything in your face.

If anything, he’d spent years trying to be your brother.

And you still couldn’t decide whether you hated him…

Or hated the fact that he might actually be genuine.
