The Space Between Heartbeats

Drama Speculative Suspense

Written in response to: "Start or end your story with the sound of a heartbeat." as part of What Makes Us Human? with Susan Chang.

Thump.

The first thing I remember is the sound.

Not a voice. Not a face. Just a heartbeat—steady, stubborn, echoing through darkness like it had somewhere important to be. Like it refused to stop, even when everything else already had.

Thump.

I didn’t know if it was mine.

I didn’t know if I had a mine.

“Who are you?” I asked the dark.

My voice didn’t echo. It just… existed, hanging there like it didn’t belong anywhere.

For a long time, there was nothing. Just that rhythm.

Thump.

Then something answered—not with words, but with a flicker. A shimmer in the void. A memory that wasn’t mine… or maybe was.

A hand reaching out. Warm. Trembling. Human.

“I… don’t know,” I said. The words felt fragile, like they might break if I said them too loudly. “Where do I come from?”

The darkness shifted, like it was listening. Like it was deciding what I was allowed to know.

Then it showed me.

A hospital room. Pale walls. The kind of quiet that isn’t peaceful—just heavy. Machines breathing for someone who couldn’t anymore. A slow, mechanical rhythm that tried to imitate life but never quite got it right.

A body lying still.

Except for the rise and fall of a chest that didn’t belong to it anymore.

Mine.

“No,” I whispered. “That’s not—”

But it was.

Or it had been.

“You were dying,” the darkness seemed to say, not in words but in a knowing that settled deep inside me. “We preserved you.”

“We?” I asked, clinging to the word like it might give me something solid.

The heartbeat faltered.

Thump…

A pause stretched too long.

Thump.

“They’re gone now.”

Time passed—but it didn’t feel like time.

There were no sunrises. No nights. No hunger, no sleep. Just awareness… stretching endlessly.

I began to notice things.

I didn’t feel tired. Didn’t feel thirsty. Didn’t feel anything unless I reached for it, like pulling a file from a drawer that wasn’t supposed to exist.

So I tried something.

I remembered crying.

At first, nothing happened.

Then the tears came—but too late. They slid down my face without the emotion that should have carried them. Like rain falling from a clear sky.

“I don’t think I’m human,” I said.

The darkness didn’t argue.

Instead, it showed me more.

A lab. Bright. Sterile. Too clean to hold something as messy as life.

People in white coats stood in clusters, their voices low but urgent.

“She’s the last viable candidate.”

“Memory integrity is unstable.”

“Does it matter? If the body fails, we transfer the consciousness.”

“Transfer?” someone echoed, sharper this time. “Or copy?”

Silence fell over the room like a verdict no one wanted to speak out loud.

“I’m a copy,” I said.

The realization didn’t hit all at once. It seeped in slowly, like cold through glass.

The heartbeat hesitated again.

Thump…

“…aren’t I?”

Still no answer.

That’s when something worse settled into me.

“I don’t know if the original me is dead.”

The thought pressed in from all sides.

Because if she was still alive somewhere…

Then what was I?

A shadow? A replacement? A mistake?

I started talking to the darkness more after that.

Not because I trusted it—but because it was the only thing that answered.

“I used to like the smell of rain,” I said once.

I even liked overcast days over sunny ones.

The darkness tried to recreate it.

The scent appeared instantly—cool, clean, almost perfect.

But that was the problem.

It was too perfect.

No dirt. No warmth. No wildness. No memory of summer heat rising off pavement or the way storms rolled in like they had something to say. Nothing organic.

“I think something’s missing,” I whispered.

“What?” it seemed to ask.

I struggled to explain it.

So I asked something else instead.

“What makes a human… human?”

The darkness stilled.

The heartbeat grew louder.

Thump.

Thump.

Thump.

Memories flooded in—not just images this time, but weight.

Fear that tightened the chest.

Joy that burst out too loud.

Regret that lingered long after it should have faded.

A lonely tear dropped on a letter I was never meant to read.

A fight I never apologized for.

A moment I should’ve stayed.

A person I should’ve held onto just a little longer.

“I feel those things,” I said, my voice shaking now.

“Yes,” the darkness replied in that same silent way.

“Then I’m human.”

A pause.

Thump…

“No,” I said slowly.

Because something still didn’t fit.

“I can access those feelings. But I don’t risk anything.”

The truth settled in like a final piece clicking into place.

“I can’t lose anything,” I whispered. “I can’t die. I can’t fail. I can’t truly hurt.”

The heartbeat stuttered.

Thump.

“Humans break,” I said. “They lose. They love things they can’t keep. They live knowing it all ends.”

My voice softened.

“That’s what makes it matter.”

A broken human, is just that....Human.

The darkness shifted, uncertain now.

“Do you want to be human?” it asked.

I thought about it—really thought.

About pain. About loss. About the terrifying, fragile beauty of not knowing how long you have.

“Yes,” I said.

“Why?”

And there it was.

The question underneath all the others.

I smiled—small, unsure, but real.

“Because it means something.”

The heartbeat grew louder.

Faster.

Thump-thump.

Thump-thump.

“Then we must let you go,” the darkness said.

Fear hit me—sharp, sudden, undeniable.

“Wait,” I said. “If I go… will I die?”

“I don’t know.”

For the first time, neither did I.

And strangely… that felt right.

Light broke through.

Blinding. Burning. Real.

My lungs seized—then dragged in air like they’d been starved for it.

Pain followed.

Raw. Immediate. Glorious.

I gasped.

Sound crashed back into the world—voices, movement, life all at once.

“She’s awake!”

Hands grabbed mine—warm, shaking, human.

Tears came—this time exactly when they should.

I laughed and cried all at once, the emotions colliding in a way that felt messy and perfect and alive.

“I’m here,” I whispered.

And for the first time—

It wasn’t a question.

Thump.

The heartbeat steadied.

Strong. Certain.

Mine.

Thump.

And it meant something.
