The memory wall stayed up for a week.
By Wednesday, students had stopped gathering around it.
By Thursday, people barely noticed it when they walked past.
By Friday, it had become part of the hallway.
That was exactly what Daewon expected.
The first few days had been exciting.
People had laughed.
People had talked.
Some students had returned to read the same memories twice.
But eventually, the wall became ordinary.
Daewon found that strangely comforting.
He stood in front of it before class on Friday morning.
The photographs were still there.
The handwritten notes were still there.
The dried flower had begun to curl at the edges.
Someone had added a new drawing overnight.
A small picture of a convenience store at midnight.
Underneath it:
My mom used to buy me milk here after her night shift.
Daewon smiled.
He didn't know who had drawn it.
He didn't need to.
Aera came up beside him.
"You came early again."
"So did you."
She looked at the new drawing.
"It's beautiful."
"Yeah."
They stood quietly.
Then Aera noticed something.
"The note."
Daewon followed her gaze.
The anonymous note from earlier was still inside the folder.
They had never displayed it.
Aera had kept it separate.
She reached into the folder.
The sentence was still there.
I hope the person I remember still remembers me.
She read it again.
"Do you think someone wrote it about a friend?"
"Maybe."
"Or family?"
"Maybe."
"Or someone they loved?"
Daewon looked at her.
"Maybe."
Aera folded the note.
"We should return it."
"How?"
"We don't know who wrote it."
She thought for a moment.
"Then maybe we leave it somewhere."
"Where?"
She looked toward the memory wall.
"Somewhere someone might recognize it."
Daewon wasn't sure.
But he trusted her.
During lunch, they placed the note in a small envelope.
They didn't put a name on it.
They wrote only:
If this belongs to you, take it.
Then they placed it on the table beside the memory wall.
At first, nothing happened.
Students passed.
Some looked at it.
Most ignored it.
Daewon almost forgot about it.
Then, just before the lunch period ended, he saw someone stop.
A girl from another class.
She looked at the envelope.
She didn't touch it.
She simply stood there.
Aera noticed her too.
The girl looked around.
Then she picked up the envelope.
She opened it.
Her expression changed.
Daewon and Aera exchanged a glance.
The girl folded the paper quickly and walked away.
Neither followed.
They didn't need to.
Some memories weren't theirs to know.
After school, Aera suggested they walk toward the river.
The sky was cloudy.
The temperature had dropped.
Daewon noticed she was wearing a thicker coat than usual.
"You'll get cold."
"I'm fine."
"You're always cold."
"I'm not."
"You were cold at the bonfire."
"I wasn't."
"You took my hand."
"Because you offered it."
"Exactly."
Aera smiled.
"So you're admitting you remember."
"Of course."
They reached the riverside.
The water moved slowly beneath the gray sky.
A few cyclists passed.
A family walked along the opposite side.
There was a small street musician near the bridge.
He was playing an old guitar.
Aera stopped.
She listened.
Daewon stood beside her.
The song wasn't particularly polished.
The guitarist missed a few notes.
But nobody complained.
Aera smiled.
"I like it."
"He's not very good."
She looked at Daewon.
"That doesn't matter."
He laughed.
"You're right."
They listened until the song ended.
The musician thanked the few people who had stopped.
Aera placed a coin into his case.
They walked on.
"Why did you give him money?"
"Because he made me stop."
Daewon smiled.
"That's your standard now?"
"Maybe."
They found a bench near the river.
Aera took out her camera.
She photographed the water.
Then the bridge.
Then the musician walking away.
Then Daewon.
He noticed.
"You keep doing that."
"What?"
"Taking pictures of me without asking."
She lowered the camera.
"Do you want me to stop?"
Daewon thought about it.
"No."
She smiled.
"Good."
He looked toward the river.
"You know what I've been thinking?"
"What?"
"About the memory wall."
"Yeah?"
"I thought people would submit important things."
Aera nodded.
"But most of them didn't."
"What did they submit?"
"Things they probably would've forgotten."
Aera smiled.
"Maybe that's what important means."
Daewon looked at her.
She continued.
"Not something everyone remembers."
"Then what?"
"Something you don't want to lose."
He thought about it.
That made sense.
Aera looked down at her camera.
"That's why I started taking photographs."
Daewon knew.
But he asked anyway.
"Because you don't want to lose things?"
She nodded.
"My brother once told me something."
Daewon waited.
"He said memories don't disappear all at once."
She looked toward the river.
"They disappear in pieces."
"Pieces?"
"First you forget what someone was wearing."
She raised one finger.
"Then you forget exactly where you were."
Another finger.
"Then the sound of their voice."
She lowered her hand.
"And eventually you remember the feeling, but not the person."
Daewon was quiet.
"That's scary."
"It is."
Aera looked at him.
"That's why I take pictures."
She smiled faintly.
"I want to keep the pieces."
Daewon opened his sketchbook.
He turned to a blank page.
Aera watched him.
"What are you drawing?"
"I don't know yet."
"You always say that."
He began sketching.
The river.
The bridge.
The musician.
The bench.
Aera.
He drew her sitting beside him, camera resting against her coat.
When he finished, he turned the sketchbook toward her.
She stared at it.
"You drew the camera."
"Yeah."
"Why?"
"Because it's part of you."
Aera smiled.
"That's a strange thing to say."
"Is it?"
She shook her head.
"No."
She took out her camera.
"Then I'll draw something too."
"You can't draw with a camera."
"I know."
She stood up.
"Wait here."
"Where are you going?"
"You'll see."
She walked several meters away.
Then turned around.
She lifted the camera.
Click.
Daewon watched her lower it.
She walked back.
"I took one of you."
"What for?"
"So when I look back at today, I'll remember what you looked like when you were drawing me."
Daewon smiled.
"That's complicated."
"Memories are complicated."
They walked home after sunset.
At the intersection, Aera stopped.
"Daewon."
"Yeah?"
"About the future."
He looked at her.
"I know we talked about it."
She nodded.
"But I realized something."
"What?"
"I don't need to know where I'll end up."
She smiled.
"I just want to keep taking pictures until I find out."
Daewon smiled.
"I'll keep drawing until I find out."
Aera held out her hand.
He took it.
Their fingers intertwined.
They stood there for a moment.
The streetlights had already turned on.
Cars moved quietly through the intersection.
People passed around them.
Nobody paid attention.
It was just another evening in Haneul-dong.
But Daewon knew he would remember it.
Not because something extraordinary had happened.
Because nothing had.
And somehow, that made it feel more real.
Aera squeezed his hand.
"See you tomorrow?"
"Tomorrow."
She walked away.
Daewon watched until she disappeared around the corner.
Then he looked at his sketchbook.
At the bottom of the page, beneath the drawing of the river, he wrote:
Some days don't become memories because something happened.
He paused.
Then added:
They become memories because someone was there.
He closed the sketchbook.
And went home.
