Morning sunlight spilled across Busan as the city slowly came alive.
For the first time in weeks, Minji woke up feeling lighter.
Jiho was alive.
The promise they had made as children hadn’t disappeared—it had simply been waiting for the right moment to return.
She smiled to herself before checking her phone.
There were dozens of messages from fans praising LUNA5’s performance at the Dream Music Festival.
Photos from the event were everywhere.
One headline caught her attention.
“LUNA5 Delivers the Festival’s Most Emotional Performance.”
Another read:
“Rookie Group Continues Their Rise to Stardom.”
Minji smiled.
After everything that had happened backstage, she had almost forgotten the performance itself.
A knock came at her hotel room door.
“Minji?”
It was Hana.
“You awake?”
“Come in.”
Hana entered carrying two cups of coffee.
“I figured you didn’t sleep much.”
Minji laughed.
“You know me too well.”
“I’ve learned.”
The two friends sat near the window overlooking the ocean.
“It’s strange,” Minji admitted.
“For ten years I believed Jiho had forgotten me.”
“And now?”
“Now it feels like no time passed at all.”
Hana smiled warmly.
“Some friendships don’t depend on time.”
“They simply wait.”
Across the hotel, Aurora was preparing to return to Seoul.
Joon stood on the balcony reading through the morning schedule when his phone vibrated.
It was an unknown number.
He hesitated before answering.
“Hello?”
The voice on the other end was calm.
“If you care about Minji…”
“…don’t let her investigate Project Starlight.”
The call ended immediately.
Joon stared at his phone.
His expression became serious.
Later that morning, LUNA5 and Aurora boarded the same KTX train back to Seoul.
The train quietly left Busan Station as mountains and coastline slipped past the windows.
Because both groups had finished their schedules, the managers allowed everyone to relax during the journey.
Yuri and Sora immediately challenged several Aurora members to a card game.
Laughter quickly filled the train car.
Meanwhile, Minji found herself sitting across from Jiho in the café carriage.
For several minutes, neither spoke.
Finally, Jiho smiled.
“I still can’t believe we’re talking like this again.”
“I know.”
“It feels unreal.”
The train gently swayed as it sped north.
“I have something for you.”
Jiho reached into his backpack.
He carefully removed a worn notebook with a navy-blue cover.
“I’ve carried this with me for years.”
Minji accepted it carefully.
Across the first page, written in neat handwriting, were the words:
Songs We Promised to Finish Together
Her eyes widened.
“You kept this?”
“Even though I couldn’t finish most of them.”
She slowly turned the pages.
There were melodies.
Lyrics.
Sketches of concert stages.
Little jokes written in the margins.
One page made her stop.
It contained a childish drawing of two performers standing beneath bright lights.
Below it was written:
One day, Minji will dance.
Jiho will play the piano.
We’ll make people smile together.
A tear landed softly on the page.
“I can’t believe you saved all of this.”
Jiho smiled.
“I never stopped believing.”
Back in Seoul, Mr.
Kang and the investigators were already waiting.
As soon as everyone arrived at the company, an emergency meeting was called.
The conference room felt unusually tense.
The lead investigator connected a flash drive to the large screen.
“We’ve finally recovered the deleted records.”
Images appeared one after another.
Financial reports.
Scholarship applications.
Bank transfers.
Donation receipts.
“There was corruption,” the investigator explained.
“But it wasn’t as widespread as we first believed.”
The room listened carefully.
“A small group of administrators secretly redirected part of the scholarship funds into private accounts.”
“They acted without the knowledge of most volunteers and teachers.”
Mr.
Kang lowered his head.
“So the people who truly cared about the children…”
“…were victims too.”
The investigator nodded.
“Exactly.”
“They spent years believing the project failed.”
“But in reality…”
“…it was betrayed by only a handful of people.”
Minji looked around the room.
“What happened to them?”
“Most were investigated years ago.”
“Several faced legal consequences.”
“Others disappeared from public life.”
“The case was quietly closed.”
Jiho frowned.
“Then why is someone still sending messages now?”
The investigator clicked to the next slide.
A photograph appeared.
It showed a young woman standing beside Project Starlight’s founder.
“This,” he said, “is Ms.
Lee Soo-ah.”
“She was the project’s archivist.”
“The person responsible for preserving every student’s records.”
“She vanished shortly after the investigation began.”
Another photograph appeared.
A much more recent one.
Taken only two weeks earlier.
The room fell silent.
“She was seen entering the abandoned academy.”
Everyone stared at the screen.
“So she was alive all this time,” Hana whispered.
The investigator nodded.
“…she’s the one who left the music box, the cassette tape, and the anonymous clues.”
Minji blinked.
“She wasn’t threatening me?”
“No.”
“She was trying to lead you back to the truth.”
That evening, Minji stood once again in the practice room where everything had begun.
LUNA5’s comeback music echoed through the speakers.
She began dancing.
Not because she had another schedule.
Not because cameras were watching.
Simply because she loved it.
The studio door quietly opened.
Jiho stepped inside carrying a small keyboard.
“You still dance whenever you’re thinking.”
Minji laughed.
“And you still bring an instrument everywhere.”
“I guess some things never change.”
He plugged the keyboard into a nearby speaker.
“What do you say?”
“Want to finish one of our old songs?”
Minji smiled.
“I’d like that.”
As Jiho played the first melody, Minji began creating choreography to match it.
The room slowly filled with music once again.
Not as two children dreaming about the future.
But as two friends who had finally found each other again.
Outside the practice room, Joon watched quietly through the glass.
A gentle smile appeared on his face.
He wasn’t jealous.
He understood.
Some people entered your life to help you discover your future.
Others reminded you of who you had always been.
Minji needed both.
She looked up and noticed Joon watching.
She smiled and waved him inside.
“You can’t stand there forever.”
Jiho turned and grinned.
“Perfect timing.”
Joon looked confused.
“For what?”
Minji laughed.
“For listening.”
Jiho added with a smile,
“And maybe telling us if our song is any good.”
The three of them laughed together.
For the first time since the mystery had begun, the future felt brighter than the past.
Yet hidden somewhere in Seoul, Ms.
Lee Soo-ah carefully watched a television report about LUNA5.
She smiled with relief.
“They’ve found each other.”
Then her smile slowly faded as another news alert appeared on the screen.
A familiar face.
One of the former administrators connected to the old corruption case had unexpectedly returned to Korea after years abroad.
Ms.
Lee whispered to herself,
“So…
you’re back.”
She immediately reached for her phone.
Because she knew something Minji didn’t.
The mystery of Project Starlight wasn’t over.
Its final chapter…
…was only just beginning.
