If You Hear This Song Tomorrow

 

Rain fell over Seoul like a memory that refused to disappear.
The city glowed softly beneath wet streetlights, blurred into watercolor streaks against taxi windows and convenience store signs. Somewhere near the Han River, an old piano melody drifted through the night like a ghost searching for someone who still remembered it.
Han Soobin sat alone in the rehearsal room of the abandoned music academy.
The piano before her was older than she was.
Its ivory keys were yellowed.
Its wood smelled faintly of dust and rain.
One pedal squeaked every time she pressed it.
But it was the only piano that still listened to her.
Soobin closed her eyes.
Then she played.
A slow melody.
Melancholic.
Beautiful enough to ache.
The notes floated through the empty room like fragments of a life she could no longer hold together.
Her mother used to hum this melody while hanging laundry on the rooftop when Soobin was a child.
Before the hospital.
Before the debt.
Before silence consumed their apartment.
Soobin stopped playing halfway through.
Her fingers trembled.
The room felt colder tonight.
She exhaled shakily and looked toward the cassette player sitting near the piano.
It had appeared three days ago.
No brand name.
No batteries.
No explanation.
Just one cassette tape inside.
A handwritten label.
"If You Hear This Song Tomorrow."
She stared at it for a long time.
Then finally pressed play.
Static filled the room.
Rain crackled faintly in the background.
And then—
A man’s voice.
Soft. Warm.
Unfamiliar.
"I don’t know who you are… but I heard your piano last night."
Soobin froze.
The voice continued.
"You sounded lonely."
Outside, thunder rolled across Seoul.
And somewhere ten years earlier, another lonely person looked up at the same rain.
Without knowing their lives had already begun to collide. 
---

"Actually, it’s definitely ridiculous."

Han Soobin hated mornings.
Mornings meant waking up to unpaid bills taped beside the refrigerator.
Mornings meant the stale silence inside her tiny apartment.
Mornings meant pretending she was okay.
At twenty-nine, she worked as a session pianist for commercials and television background scores.
No one knew her name.
She played melodies that people forgot the second they ended.
Sometimes she wondered if she was disappearing too.
That morning, she stood inside a convenience store holding instant coffee while watching rainwater crawl down the glass windows.
The cashier stared at her.
"You look exhausted again," he said.
Soobin forced a smile.
"That’s my natural face."
He laughed.
She didn’t.
Outside, the city moved too quickly.
Umbrellas.
Bus brakes.
Shoes splashing puddles.
People who still had somewhere to belong.
Her phone buzzed.
Lee Nari.
Nari never texted normally.
"IF YOU IGNORE ME TODAY I WILL DIE."
Soobin sighed.
"What happened now?"
"Blind date disaster. Emergency noodles tonight."
Despite herself, Soobin smiled.
Nari was chaos wrapped in expensive lipstick.
Bright.
Loud.
Hopelessly emotional.
The exact opposite of Soobin.
And maybe the only reason she still remembered how to laugh.
---
That evening, Soobin returned to the abandoned music academy.
The building was scheduled for demolition in three months.
Until then, the owner allowed struggling musicians to rent rehearsal rooms cheaply.
The hallway lights flickered.
Rain tapped softly against cracked windows.
When she entered Room 402, the cassette player was still there.
Waiting.
Her heartbeat slowed strangely.
She approached it carefully.
There was a new tape inside.
Not the same one.
A different label.
"You didn’t answer yesterday."
Soobin stared.
Her throat tightened.
She pressed play.
Static.
Then the same male voice.
"Maybe this is ridiculous."
A faint laugh.
Rain echoed faintly behind him.
"But I kept waiting for your piano tonight."
Soobin’s fingers slowly curled.
"Who are you…?" she whispered.
The voice continued.
"My name is Yoo Minho. I own a café near Seochon. Or… I’m trying to own one. Business isn’t exactly great."
He paused.
"You play like someone who lost something important."
Soobin suddenly switched the tape off.
The room became silent.
Too silent.
Her chest hurt unexpectedly.
Because somehow…
He was right. 
---
Yoo Minho lived in 2016.
His café was called Moon Rain.
It sat on a quiet alley lined with old bookstores and flickering neon signs.
At night, jazz records played softly through dusty speakers while rainwater gathered beneath the outdoor lights.
Most customers came for warmth.
Some came because they were lonely.
Minho understood both.
That night, he sat alone behind the counter listening to cassette static.
He had found the tape recorder inside a secondhand antique shop two weeks earlier.
The owner told him it was cursed.
Minho bought it immediately because it was cheap.
Now he stared at the cassette in disbelief.
Because after he recorded his message yesterday…
Someone had answered.
A woman’s voice.
Quiet.
Careful.
Beautiful.
"I think you have the wrong person."
Static crackled.
"And this isn’t funny."
Minho replayed it for the seventh time.
A slow smile appeared.
For the first time in months, the café didn’t feel empty.
---
The recordings continued.
At first cautiously.
Then daily.
They never exchanged photos.
Never asked impossible questions.
Never explained how it worked.
Because some miracles break if you touch them too much.
Instead, they talked about ordinary things.
Coffee.
Rain.
Favorite songs.
Loneliness.
Minho described the smell of roasted beans in the morning.
Soobin described the sound of Seoul at 3 a.m.
One night, Minho asked:
"Do you ever feel like everyone else learned how to live except you?"
Soobin sat beside the piano for a long time before recording her answer.
"Every day."
---
Weeks passed.
Something fragile began growing between them.
Not love yet.
But recognition.
Like two people standing in darkness and realizing someone else was there all along.
One rainy evening, Soobin visited the address Minho mentioned.
Moon Rain Café.
Only—
It wasn’t there.
Instead, a parking lot stood beneath cold fluorescent lights.
Her stomach dropped.
An elderly street vendor noticed her staring.
"There used to be a café there," he said.
"Long time ago."
"What happened to it?"
"Owner disappeared after a fire."
Soobin’s face slowly paled.
"Disappeared?"
The vendor nodded.
"Ten years ago."
Rain poured harder.
And suddenly the cassette tapes no longer felt magical.
They felt dangerous.
---
That night, Soobin could barely breathe.
She inserted a new tape with shaking hands.
"Minho."
Silence.
"What year is it there?"
Hours later, she received his reply.
"2016."
Her eyes widened.
The tape slipped from her fingers.
Thunder shook the windows.
Ten years.
Ten entire years separated them.
And somehow…
his voice still reached her.
---
Minho didn’t believe her at first.
He laughed.
Then stopped laughing when she described events that hadn’t happened yet.
A celebrity scandal.
A subway accident.
The first snowfall arriving late.
Things no stranger could know.
He sat alone in the café after closing time listening to her voice.
His expression slowly changed.
"So you’re telling me…"
He swallowed.
"You’re living in 2026?"
"Yes."
Static.
A long silence.
Then Minho whispered:
"That means…"
He couldn’t finish.
Because suddenly the future felt real.
And terrifying.
---
Their connection deepened after that.
Maybe because impossible truths create intimacy faster than ordinary life ever could.
Minho began leaving recordings of the café during rainy nights.
Customers laughing softly.
Coffee grinders.
The sound of him washing cups.
Soobin listened while lying awake at 2 a.m.
Sometimes she replayed them just to feel less alone.
In return, she recorded piano melodies for him.
Songs she never played for anyone else.
One night Minho said quietly:
"I think your music remembers things you don’t say out loud."
Soobin stared at the cassette player.
No one had ever understood her like that.
Not even herself.
---
Nari noticed the change first.
"You’re smiling at your phone now."
They sat beneath a convenience store awning sharing ramen cups while rain fell around them.
Soobin looked away.
"Am not."
"You literally smiled at nothing three times today."
"Maybe I’m having a stroke."
Nari narrowed her eyes.
"There’s a man."
"There isn’t."
"Then why do you suddenly look alive again?"
The question landed too honestly.
Soobin fell quiet.
Because she didn’t know the answer.
---
Minho had his own wounds.
His father drowned in debt before dying of a stroke.
His mother left afterward.
He spent years working night jobs to keep the café alive because it was the only dream he had inherited from himself.
Sometimes, during recordings, his exhaustion slipped through.
Sometimes Soobin heard him crying softly after too much alcohol.
But he always laughed afterward.
As if apologizing for being human.
One night he asked:
"Did you ever love someone enough to ruin yourself?"
Soobin closed her eyes.
A flashback surfaced.
A hospital corridor.
Her mother whispering apologies through oxygen tubes.
The sound of machines failing.
"Yes," she whispered.
"My mother."
---
Winter arrived.
Snow covered Seoul in pale silence.
Minho described the first snowfall in 2016 while Soobin watched the same snow falling ten years later.
It felt intimate.
Like standing beneath the same sky despite time refusing to allow it.
One evening, Minho recorded himself walking beside the Han River.
Wind crackled through the tape.
"I wish you could see this," he said.
"The river looks lonely tonight."
Soobin listened while standing at the Han River herself.
Ten years apart.
Same river.
Same loneliness.
Tears suddenly filled her eyes.
Because she could almost imagine him there.
Walking beside her.
---
The first time they almost said "I miss you" neither of them finished the sentence.
Minho started:
"These days, when something happens, you’re the first person I want to tell—"
Then silence.
Soobin pressed the cassette tightly in her hands.
Her heartbeat became painful.
She whispered into the recorder:
"Me too."
---
Spring came slowly.
Cherry blossoms appeared across Seoul like fragile confessions.
Minho recorded café customers laughing under blooming trees.
Soobin sent him piano compositions inspired by rainstorms.
They began sharing smaller things.
Favorite childhood snacks.
Dreams.
Fears.
Minho hated hospitals.
Soobin hated birthdays.
Neither liked being pitied.
Both stayed awake too late.
And somewhere between cassette tapes and midnight silences…
they fell in love.
Quietly.
Without permission.
---
The realization terrified Soobin.
Because loving someone unreachable was the cruelest thing she had ever done to herself.
She tried distancing herself.
Stopped replying for three days.
Minho kept recording messages anyway.
At first playful.
Then worried.
Then heartbreakingly soft.
"If I said something wrong… I’m sorry."
Rain echoed behind his voice.
"Just… don’t disappear without saying goodbye."
That night Soobin broke down crying in the rehearsal room.
Because people always left her first.
But Minho sounded afraid she would leave him.
No one had ever sounded that way before.
---
When she finally answered, her voice trembled.
"I’m still here."
Minho exhaled shakily on the other side of time.
And somehow she heard relief inside the silence.
---
Months later, Soobin discovered the fire happened on December 24th, 2016.
Christmas Eve.
Moon Rain Café burned down after midnight.
One person disappeared.
Yoo Minho.
No body was found.
Soobin stared at the old newspaper article until her hands shook.
The date was only eleven days away for him.
Fear consumed her.
She recorded frantically.
"Minho, listen to me carefully."
Her breathing cracked.
"You cannot stay at the café on Christmas Eve."
Silence.
"There’s going to be a fire."
Hours later, his reply arrived.
Static.
Then laughter.
Nervous laughter.
"You sound insane right now."
"I’m serious."
"Soobin—"
"Please."
Her voice shattered.
Minho fell silent.
For the first time, he sounded genuinely afraid.
---
As Christmas approached, tension consumed every recording.
Minho tried joking.
Soobin stopped sleeping.
Nari noticed dark circles beneath her eyes.
"What’s happening to you lately?"
Soobin nearly told her everything.
But how do you explain loving someone history already erased?
---
Three nights before Christmas, Minho recorded the sound of the café closing.
Rain tapped softly outside.
"I keep thinking about something," he said.
"If we met normally… do you think we would’ve liked each other?"
Soobin covered her mouth.
Tears burned her eyes.
She answered immediately.
"I think I would’ve loved you too much."
When Minho heard the tape, he sat motionless behind the counter for a very long time.
Then he smiled sadly.
Because that was the closest either of them had come to confessing.
---
Christmas Eve arrived with snow.
The city glowed beneath warm lights and lonely music.
Soobin stayed beside the cassette player all night.
Waiting.
Praying.
Hours passed.
Nothing.
Then finally—
A tape appeared.
Her hands trembled violently as she pressed play.
Static screamed through the speakers.
People shouting.
Glass breaking.
Fire alarms.
Then Minho’s voice.
Breathing hard.
"Soobin—"
The sound cut.
Then returned.
"You were right."
Smoke crackled behind him.
"There was an electrical fire in the kitchen."
Soobin began crying immediately.
"Get out!"
"I tried—"
Something collapsed loudly.
Minho coughed violently.
"The back exit is blocked."
Soobin screamed his name.
But time could not hear her.
Static swallowed the tape.
Then silence.
Complete silence.
The cassette stopped spinning.
And for the first time since this impossible connection began…
there was nothing.
---
Three months passed.
No tapes.
No voice.
Nothing.
Spring returned to Seoul anyway.
Cruelly.
People still laughed.
Cherry blossoms still bloomed.
The world still moved.
Soobin did not.
She stopped composing.
Stopped sleeping.
Stopped answering calls.
The rehearsal room became her graveyard.
One rainy evening, Nari finally snapped.
"You’re disappearing!"
Soobin stared blankly at the piano.
"Maybe I already did."
Nari’s expression broke.
"Who hurt you this badly?"
Soobin almost answered.
Instead she whispered:
"Someone who doesn’t exist anymore."
---
That night, after Nari left, Soobin sat alone beside the cassette player.
Rain hammered the windows.
She touched the tape recorder softly.
"I miss you," she whispered.
A click echoed.
Her breath stopped.
The cassette began turning by itself.
Static flooded the room.
Then—
Minho’s voice.
Weak.
Distant.
"Soobin…"
She burst into tears instantly.
"Minho?"
"I don’t have much time."
His breathing sounded uneven.
Hospital machines beeped faintly.
"I survived the fire."
Soobin collapsed against the piano crying.
"Thank God…"
"But something changed after that night."
Static crackled violently.
"The tapes are becoming unstable."
She froze.
"What do you mean?"
A long silence.
Then:
"I think time is trying to correct itself."
---
Minho explained slowly.
After surviving the fire, strange things began happening.
Photographs disappearing.
People forgetting conversations.
Objects moving.
As if reality itself rejected his survival.
"Maybe I was supposed to die that night," he whispered.
"Don’t say that."
"Soobin…"
Pain filled his voice.
"If changing fate means erasing you too—"
"Stop."
She wiped tears furiously.
"We’ll figure something out."
But fear already lived inside both of them.
Because deep down…
They knew love alone could not defeat time.
---
The tapes became unpredictable afterward.
Sometimes days passed without contact.
Sometimes recordings arrived distorted.
Fragments.
Minho laughing.
Rain.
Music.
Half-finished sentences.
The distance between them felt like it was tearing wider.
And yet their feelings only deepened.
One night Minho asked quietly:
"Can I tell you something selfish?"
"Okay."
"Even if this ends badly…"
He inhaled slowly.
"Meeting you was still worth it."
Soobin cried silently while listening.
Because she felt the exact same way.
---
Summer arrived heavy and humid.
Soobin visited the Han River more often now.
It reminded her of him.
One evening she sat beneath glowing bridge lights while couples walked past holding hands.
Her phone buzzed.
Nari.
"I’m outside your apartment. Open the door before I break in."
Soobin laughed weakly for the first time in weeks.
When she returned home, Nari had brought beer and fried chicken.
"Congratulations," Nari announced.
"You’re officially too depressed to live alone tonight."
They drank on the rooftop beneath warm summer wind.
After a long silence, Soobin finally asked:
"Do you think people can fall in love without meeting?"
Nari looked at her carefully.
"You already did, didn’t you?"
Soobin’s eyes filled immediately.
Nari sighed softly.
"Then he must be someone special."
---
The next tape arrived during a thunderstorm.
Minho sounded unusually serious.
"I found something."
Static crackled.
"The antique shop where I bought the recorder."
Soobin sat upright.
"What about it?"
"The owner remembered another couple using it years ago."
A pause.
"They also disappeared."
Cold fear crawled through her.
"What happened to them?"
"Nobody knows."
Rain hammered loudly against the café windows behind him.
"But the owner said something strange."
Static.
"He said the recorder only appears to people carrying unfinished grief."
Soobin stared at the darkness of her apartment.
Her chest hurt quietly.
Because maybe that explained everything.
Maybe they were never chosen by magic.
Maybe they were chosen by loneliness.
---
One evening, Minho finally confessed.
No dramatic music.
No perfect timing.
Just rain.
And exhaustion.
"I think I love you."
Soobin stopped breathing.
Static hummed softly between them.
Minho laughed nervously.
"Actually, no. That sounded too small."
A pause.
"I know I love you."
Soobin covered her trembling mouth.
Outside her window, Seoul blurred beneath rain.
"You don’t even know what I look like," she whispered.
"I know your heart."
The simplicity destroyed her.
Tears slid down silently.
Then she whispered:
"I love you too."
And somewhere ten years earlier, Yoo Minho closed his eyes as if the universe had finally become kind.
---
But happiness in stories like theirs never lasts long.
Two weeks later, the tapes stopped again.
Completely.
Days passed.
Then one final cassette appeared.
Only three words were written on it.
"Don’t find me."
Soobin’s blood ran cold.
She pressed play.
Minho’s voice emerged faintly.
Broken.
"If you’re hearing this… it means I made my decision."
Her breathing became shaky.
"Minho—"
"The more we change things, the more unstable reality becomes."
Glass shattered somewhere behind him.
"People around me are getting hurt now."
Static exploded violently.
"I can’t let you disappear because of me."
Tears streamed down her face.
"No—"
"Soobin."
His voice softened.
"Please live happily."
The tape ended.
And this time…
No new tape replaced it.
---
Soobin broke completely after that.
She stopped going to work.
Stopped answering Nari.
Stopped playing piano.
Weeks dissolved into silence.
Then one rainy afternoon, she found herself standing outside the old parking lot where Moon Rain Café once stood.
She stared at the empty space for a long time.
Wind moved softly through the alley.
And suddenly—
A melody.
Faint.
Piano music.
Her piano music.
Soobin turned sharply.
At the far end of the alley stood an old bookstore she had never noticed before.
A single light glowed inside.
She entered slowly.
Dust floated through warm yellow light.
Books towered everywhere.
Behind the counter sat an elderly woman listening to a cassette tape.
Without looking up, she said:
"You finally came."
Soobin froze.
"Excuse me?"
The woman looked at her gently.
"Love leaves echoes behind."
She slid a small key across the counter.
"Moon Rain still exists. Just not where you think."
---
The key led Soobin to an abandoned rooftop greenhouse overlooking Seoul.
Inside stood a piano.
And beside it—
A cassette recorder.
New.
Waiting.
Her hands shook violently.
She pressed play.
Static.
Then Minho’s voice.
Very softly.
"If you found this…"
Rain echoed faintly.
"Then maybe time still feels guilty."
Soobin began crying instantly.
"I searched for a way back to you."
A pause.
"But every path ends the same way."
The tape crackled painfully.
"One of us disappears."
Soobin closed her eyes.
The city lights blurred beneath tears.
"Then I’ll disappear instead," she whispered.
But the tape had already ended.
---
The mid-story truth revealed itself slowly.
Minho had survived the fire.
But only because Soobin warned him.
Originally, he died in 2016.
In the untouched timeline, Moon Rain burned down with him inside.
Soobin never met him.
Never healed.
Never composed music again.
She eventually abandoned piano entirely.
The cassette recorder changed that.
By saving Minho, she altered her own future.
But the universe demanded balance.
A life preserved.
A life erased.
And now reality was collapsing around the contradiction.
---
Nari became the first casualty.
One evening Soobin visited her apartment.
Nari opened the door smiling politely.
"Can I help you?"
Soobin laughed awkwardly.
"Very funny."
But Nari’s expression remained confused.
"I’m sorry… have we met?"
The world tilted beneath Soobin.
Memories were changing.
The closer she became to Minho…
The more her original life disappeared.
---
That night Soobin shattered.
She screamed.
Cried.
Threw cassette tapes across the rehearsal room.
"What do you want from us?!"
Rain thundered outside.
Her reflection in the piano looked unfamiliar now.
Like someone slowly fading.
Then suddenly—
The recorder clicked.
Minho’s voice emerged urgently.
"Soobin listen carefully."
She fell to her knees.
"I found a way."
Static roared.
"There’s one place where our timelines overlap physically."
Her breath caught.
"Where?"
"The Han River pedestrian tunnel near Banpo Bridge. Midnight. August 14th."
A pause.
"Exactly ten years apart."
Her hands trembled violently.
"Can we meet?"
Minho didn’t answer immediately.
Then softly:
"I don’t know."
---
August 14th arrived wrapped in rain.
Of course it rained.
Their entire love story belonged to rain.
At 11:57 p.m., Soobin stood inside the empty tunnel beneath flickering lights.
Her heart pounded uncontrollably.
Footsteps echoed.
But no one appeared.
Then—
A figure.
Blurry.
Transparent.
At the opposite end of the tunnel.
Yoo Minho.
Ten years away.
He stared at her in disbelief.
Soobin covered her mouth crying.
Because he was real.
Not static.
Not imagination.
Real.
Minho slowly walked closer.
The air around them shimmered strangely.
Like reality itself resisting.
When they were finally only inches apart, both stopped.
Neither spoke.
They simply looked at each other.
The person who had carried their loneliness.
The voice that survived impossible distance.
Minho laughed shakily first.
"You’re prettier than I imagined."
Soobin cried harder.
"You’re late."
He smiled.
God, his smile.
It ruined her instantly.
Minho slowly lifted his hand.
Soobin lifted hers too.
Their fingertips touched.
A violent sound exploded through the tunnel.
Lights shattered.
Reality warped.
Pain shot through both of them.
Minho grabbed her instinctively.
And for one impossible second—
they held each other.
Warm.
Real.
Alive.
Soobin buried her face against his chest sobbing.
Minho held her like someone terrified of waking up.
"I found you," he whispered brokenly.
Then suddenly the tunnel screamed with blinding light.
Minho’s body began fading.
Soobin panicked.
"No no no—"
He cupped her face desperately.
"Listen to me."
Tears filled his eyes.
"You have to let me go."
"I can’t."
"You can."
Rainwater dripped from his hair.
"You taught me how to live again."
His voice cracked.
"Now let me save you too."
And before she could stop him—
Minho kissed her.
Soft.
Heartbreaking.
Full of goodbye.
The world shattered white.
And he disappeared.
---
Soobin woke up alone beside the Han River at dawn.
No tunnel lights.
No cassette recorder.
No proof.
Only one cassette tape in her coat pocket.
She pressed play with trembling fingers.
Minho’s final message filled the morning air.
"If you’re hearing this song tomorrow…"
A sad laugh.
"Then it means you survived."
Birds echoed faintly behind him.
"I used to think loneliness was permanent."
A pause.
"Then I met you."
Soobin cried silently beneath pale sunrise.
"Maybe we weren’t meant to stay together."
His voice softened.
"But loving you changed every version of me."
The tape crackled gently.
"So please keep playing piano."
A final breath.
"And if there’s another life after this…"
Very quietly:
"Find me earlier."
The tape ended.
---
Afterward, time stabilized.
Nari remembered her again.
The strange disappearances stopped.
The cassette recorder never returned.
But Soobin changed forever.
She began composing again.
Slowly.
Painfully.
Not because the grief vanished.
But because love had taught her grief could coexist with living.
Her compositions became famous online.
People described them as:
"Music that feels like missing someone you’ve never met."
They weren’t wrong.
---
Two years later, Soobin performed her first public piano concert.
The venue overlooked the Han River.
Rain fell softly outside the glass walls.
Nari sat proudly in the front row crying before the performance even began.
Soobin laughed quietly.
Then she sat before the piano.
The room fell silent.
She began playing the melody.
Their melody.
The one that crossed ten years.
As music filled the hall, Soobin suddenly noticed someone standing near the back exit.
A man.
Tall.
Dark coat.
Watching her.
Her fingers faltered.
The man smiled faintly.
Warm.
Familiar.
Then the lights shifted.
And he was gone.
After the concert, Soobin searched the entire building.
Nothing.
Only rain.
And the distant sound of the Han River at night.
---

Years later, Seoul still rained the same way.
Vintage cafés still glowed softly in quiet alleys.
Cassette tapes still gathered dust in forgotten shops.
Lonely people still wandered beneath neon reflections searching for someone who understood them.
And somewhere inside an old antique store, hidden between shelves of broken radios and faded photographs…
A cassette recorder waited patiently.
For the next unfinished heart.
For the next impossible love story.
For the next person brave enough to answer when loneliness called back.
Outside, rain began falling softly over Seoul.
Like music.
Like memory.
Like someone whispering from another lifetime:
"If you hear this song tomorrow…"
"Please don’t forget me."
