Work Text:
The library was never truly silent anymore.
Before the war, people had come there laughing, students arguing over philosophy, young couples whispering between the poetry shelves, children chasing each other until the librarian shushed them.
Now, after the war had finally ended, the quiet felt heavier.
Like something fragile might break if anyone spoke too loudly.
Sunoo preferred the late hours.
By nine in the evening, the last visitors had gone home. The lamps glowed softly across the long wooden tables, their warm circles of light reflecting on polished floors worn smooth by decades of footsteps.
Outside, the winter wind pressed against the tall windows. Snow drifted slowly through the streets of the small city, muting everything.
Inside the library, only Sunoo remained.
She moved carefully through the aisles with a basket of returned books balanced against her hip.
It was her nightly routine. Check each book for damage, erase pencil marks, remove scraps of paper people sometimes left behind.
War had made people careless with books.
Or sentimental.
Letters were sometimes tucked between the pages, quick notes from husbands leaving for the front to their wives. Occasionally a pressed flower. Once, a photograph.
Sunoo never read the letters.
She always returned them to the front desk so the owners could retrieve them later.
Tonight’s stack was smaller than usual.
Fewer visitors these days. Fewer soldiers passing through town.
Fewer young men at all.
Sunoo carried the basket to the front desk and began sorting the books.
A travel guide to Switzerland.
A French grammar book.
A worn copy of Shakespeare.
Sunoo opened the Shakespeare first.
Her eyes moved automatically over the page, checking for damage. Then she paused.
There was a faint pencil mark in the margin.
Not unusual.
But when Sunoo leaned closer, she realized it wasn’t a line.
It was writing. Very small writing.
L - 3 - S - 12 - H - 5
Sunoo frowned slightly. She adjusted the lamp so the light fell more clearly across the page.
The marks were carefully placed between printed lines of Romeo and Juliet, almost hidden unless someone looked closely.
She turned the page.
Another set of markings appeared.
S - 7 - O - 18
Sunoo tilted her head.
“Strange,” she murmured.
People underlined passages all the time, mindless marking that Sunoo usually didn’t care about, but this wasn't underlining. And it wasn’t notes either.
It looked deliberate.
Almost like--
Sunoo flipped through the rest of the book.
More markings appeared in several places.
Always letters.
Always numbers.
And always written very lightly, as if the writer hoped no one else would notice.
Sunoo closed the book slowly.
For some reason, the quiet library felt slightly less ordinary than it had a moment ago.
<><><><>
The next afternoon, the library door burst open so suddenly that Sunoo nearly dropped the book she was shelving.
A gust of icy wind swept inside.
And with it came a boy who looked entirely too alive for such a quiet building.
He shook snow from his coat and glanced around with quick, bright eyes.
Sunoo watched him approach the desk.
The stranger looked young, perhaps around Sunoo’s age, but carried himself with restless energy that filled the room immediately.
“Hi,” he said. “Are you the librarian?”
Sunoo blinked. “...Yes.”
The stranger grinned. “Great. I’m looking for newspapers from 1916. And maybe books about wartime censorship.”
Sunoo studied him for a moment. “You’re researching the war?”
“Propaganda,” the boy said.
He tapped the camera hanging around his neck.
“I’m a journalist.”
That explained the chaotic energy.
Sunoo stood.
“Follow me.”
They walked toward the archive shelves together while the boy looked around with fascination.
“You work here alone?”
“Mostly.”
“Doesn’t it get lonely?”
Sunoo considered that question.
“...No.”
The journalist laughed softly. “You’re interesting.”
Sunoo had no idea how to respond to that.
They reached the newspaper cabinets. As Sunoo opened a drawer, the Shakespeare book slipped from under her arm and fell onto the table beside them.
It landed open.
The journalist leaned closer. His eyes immediately narrowed. “...What’s this?”
Sunoo hesitated. “I… I found it last night.”
The boy picked up the book carefully. His expression sharpened.
“That’s a code.”
Sunoo blinked. “A code?”
The journalist looked delighted. “Oh, absolutely.” He flipped through the pages quickly. “Letters and numbers arranged like this? Hidden in margins?”
He looked up.
“Someone was sending messages.”
Sunoo stared at the page again.
“To who?” she asked.
The journalist’s grin softened slightly. “That’s what we’re going to find out.”
He extended a hand. “I’m Riki.”
Sunoo hesitated for half a second before shaking it.
“...Sunoo.”
<><><><>
They stayed after closing.
Riki insisted.
Sunoo pretended she needed to finish cataloguing.
The truth was she was curious. Very curious.
They spread books across the desk beneath the lamps. Riki worked quickly, scribbling notes in a small notebook while muttering to himself.
Sunoo watched.
“You’ve done this before,” she said.
“Sometimes soldiers hide messages in newspapers,” Riki said. “So censors won’t catch them.”
He tapped one of the coded lines. “This one’s simple. Probably a substitution cipher.”
He began writing letters beneath the numbers.
Minutes passed.
Then suddenly, Riki stopped.
“...Oh.” he murmured.
Sunoo leaned closer. “What?”
Riki slowly turned the notebook toward her.
The letters had been rearranged into a sentence. Not coordinates. Not military information. Just words.
I missed you today.
Sunoo stared at it. “That’s… not a military code.”
Riki flipped to another marked page. After a few moments of writing, another message appeared. He read it softly.
The library is quiet without you.
The air between them changed. Sunoo felt something strange in her chest.
“Those aren’t war messages,” she said.
Riki looked up.
“No.”
His voice was quieter now.
“They’re love letters.”
<><><><>
Two days later, they found another hidden in a thin poetry book.
The code was longer. Riki deciphered it slowly while Sunoo watched his pencil move across the page.
Finally, the message appeared.
Riki read it aloud.
Heeseung,
Today, the snow fell outside the hospital yard. It reminded me of the way you used to brush dust off old books with your sleeve.
I wanted to tell you something that day in the library, but the room was full of other soldiers and I was afraid.
If we both come home, I will say it properly.
-Sunghoon
Sunoo’s breath caught.
“So there are two of them,” she said softly.
Riki nodded. “Sunghoon and Heeseung.”
Sunoo imagined them. Two soldiers sitting at these same tables months ago, pretending to read, writing messages in pencil when no one was looking. The thought made her chest ache slightly.
“Why hide the letters in books?” Sunoo asked.
Riki smiled faintly. “Because books travel.”
He tapped the shelf beside them. “If both of them visited the library before deployment, they could leave messages for each other here.”
Sunoo looked at the shelves differently now.
Like every book might be hiding a heartbeat.
<><><><>
The next message took longer to decode. It appeared in three separate books and Riki finally pieced it together late one evening.
When he finished, he didn’t read it immediately. He glanced at Sunoo first.
“Ready?”
Sunoo nodded and Riki cleared his throat.
Sunghoon,
I found your last message in the Shakespeare book. I almost laughed in the middle of the reading room.
You always did like dramatic places for confessions.
I wish the war would end soon. There are too many things I want to tell you, and I’m afraid time will steal them from us.
If you come back first, wait for me in the library. I will find you there.
--Heeseung.
Neither of them spoke for a moment.
Finally, Sunoo said quietly, “They loved each other.”
Riki nodded slowly. “Yeah.”
<><><><>
The final code appeared in a military strategy book that hadn’t been borrowed in months.
Riki deciphered it slowly.
This time, the handwriting looked rushed.
Uneven.
Like the writer had been in a hurry.
Sunoo noticed Riki’s pencil stop moving.
“...Riki?”
Riki looked up. His usual easy smile was gone.
“You should read this yourself.”
He slid the notebook across the table.
Sunoo looked down.
The message was longer than the others. And the words felt heavier.
Heeseung,
If this message reaches you, then I couldn’t come back to the library.
The front is worse than anyone says. But I don’t regret anything.
Meeting you between the poetry shelves was the best accident of my life.
If the war takes me, promise you’ll still visit the library sometimes.
There will always be a part of me waiting for you between the pages.
--Sunghoon.
The library felt unbearably quiet.
Sunoo closed the notebook slowly.
“We don’t know what happened to them,” she said.
“No,” Riki said softly.
Outside, the war was finally nearing its end.
Inside the library, a love story remained unfinished.
Written in pencil.
Hidden between the margins.
