Chapter 10: The Forgotten Box

The apartment was unusually quiet.

Outside, the evening traffic drifted past in a distant hum, occasionally interrupted by the sound of rain tapping gently against the windows. Inside, only the rustling of paper broke the silence as Seo Do-hyun continued reorganizing the shelves in his study.

The previous evening's cleaning had left neatly stacked cardboard boxes against one wall, each labeled according to the year or subject they contained. Most were filled with textbooks he no longer needed, lecture notes from his undergraduate years, or research articles he had once thought would be useful forever.

His bookshelf finally had enough space for the new medical references he would inevitably purchase next semester.

"...Almost done."

He wiped a thin layer of dust from the top shelf before reaching for the final box.

Unlike the others, this one was noticeably older.

Its corners had softened with age, and the tape sealing the lid had begun to peel away on its own. There wasn't a label anywhere on the box, only faint marks left behind where an old sticker had once been attached.

Do-hyun frowned.

"I don't remember packing this."

He carried it to the floor and carefully opened the lid.

The contents immediately told him why he had forgotten it.

There were no medical books inside.

Instead, the box held old college notebooks, loose sheets of paper, folders filled with assignments, and several worn envelopes containing miscellaneous documents from his pre-med years.

He smiled faintly.

"So this is where everything went."

One by one, he sorted through the contents.

Old biology quizzes.

Laboratory reports.

Chemistry worksheets.

Certificates from seminars he barely remembered attending.

Each item represented another small step that had eventually led him into medical school.

Most of it could probably be thrown away.

He reached for another folder resting near the bottom of the box.

Unlike the others, it wasn't transparent.

It was made of thick black cardstock, its edges slightly bent from years of being tucked away beneath heavier books. Across the front, written in fading blue ink, were two simple words.

Project H.

"...Project H?"

The name meant nothing to him.

Curious, he opened the folder.

Several loose pages slid onto the floor.

Do-hyun bent down to gather them, but as his eyes scanned the first sheet, his hand froze.

It wasn't a lecture note.

Nor was it a laboratory report.

It was...

A character profile.

Detective Han Ji-seok

Age: 34

Occupation: Violent Crimes Detective

Strengths: Exceptional observational skills. Calm under pressure. Notices details others ignore.

Weaknesses: Insomnia. Survivor's guilt. Difficulty trusting others.

Do-hyun blinked.

"...What?"

He flipped to the next page.

Another profile.

Victim No. 1 — Park Min-soo

Occupation: Lawyer

Found dead inside his office.

Cause of death appears to be suicide...

...but something doesn't add up.

His brows slowly knitted together.

"What is this?"

He turned another page.

Then another.

Soon the floor around him became covered with handwritten notes.

Timelines.

Maps.

Lists of suspects connected by arrows.

Newspaper clippings carefully taped onto notebook paper.

Even rough sketches of crime scenes filled the margins.

His heartbeat quickened.

It wasn't because he found the material disturbing.

It was because every page was unmistakably written in his own handwriting.

"...I wrote this?"

He searched deeper into the folder.

Near the bottom lay a thick stack of paper held together by a binder clip.

The title page had yellowed slightly with age.

At the center, printed in bold letters, was a title he had completely forgotten.

The Silent Witness

Below it, in much smaller handwriting, someone had written:

Draft 7

Do-hyun stared silently.

Draft...

Seven?

He slowly turned the page.

Chapter One

Rain poured relentlessly over the city as Detective Han Ji-seok stepped across the yellow police tape...

He stopped reading after only a few paragraphs.

Not because it was poorly written.

Because it wasn't.

The prose was rough in places, and a few sentences felt awkward, but the atmosphere immediately pulled him in. The opening murder was carefully constructed. Every line hinted at details that seemed insignificant yet strangely deliberate.

Without realizing it, he continued reading.

One chapter became two.

Then three.

Each chapter introduced new suspects, hidden motives, and clues cleverly concealed within ordinary conversations.

Occasionally, handwritten notes filled the margins.

"Foreshadow this earlier."

"The killer shouldn't appear suspicious yet."

"Readers must suspect the detective here."

There were entire pages devoted to possible endings.

Alternative murder methods.

Different culprit reveals.

Even diagrams explaining how each clue connected to the next.

It wasn't simply a story.

It was months of planning.

Perhaps years.

Do-hyun struggled to remember.

Then...

A memory surfaced.

He was nineteen years old.

Sitting inside the university library after finishing his biology assignment.

Instead of going home immediately, he had opened a blank notebook and begun writing the opening chapter of a detective novel simply because he thought it would be fun.

Another memory followed.

Late nights spent researching forensic science—not for class, but to make the murders feel realistic.

Conversations with classmates where he secretly asked hypothetical questions, pretending they were for an assignment while quietly testing whether anyone could solve his mystery.

He remembered carrying this folder almost everywhere during his undergraduate years.

Whenever inspiration struck, he scribbled another idea before he could forget it.

He remembered staying awake until sunrise trying to perfect a plot twist.

He remembered arguing with himself over which suspect should become the murderer.

He remembered laughing after finally writing an ending that even he hadn't anticipated.

And then...

The memories stopped.

Medical school.

Entrance examinations.

Orientation.

Endless lectures.

Somewhere between one responsibility and the next...

The folder had disappeared.

Not because he had chosen to abandon it.

Life had simply become too busy.

He had packed it into a box with the intention of returning someday.

Someday had quietly become years.

Do-hyun looked around the apartment.

Medical textbooks surrounded him.

Anatomy.

Pathology.

Pharmacology.

Clinical Medicine.

For a long moment, he simply sat there, the forgotten manuscript resting in his lap.

He couldn't believe something this important had slipped so completely from his memory.

More than that...

He couldn't believe how alive he had looked in those handwritten notes.

Every margin overflowed with excitement.

Every correction reflected someone eager to improve.

Every page carried the unmistakable enthusiasm of a young man creating something because he genuinely loved it.

He couldn't remember the last time he had felt that way about anything.

Outside, the rain continued falling.

The clock on his desk quietly passed midnight.

His medical textbooks remained unopened.

Instead, Do-hyun turned another page.

Then another.

He read his younger self's words with growing fascination, occasionally smiling whenever he encountered an old comment scribbled in the margins.

"This twist is genius."

"No... that's too obvious. Rewrite it."

"Make readers cry here."

He laughed softly.

"I really wrote all of this..."

The apartment remained silent except for the turning of pages.

For the first time in years...

Seo Do-hyun stayed awake—not because of medicine, but because of a story he had forgotten he wrote.
