The café was quiet again.
Too quiet.
The soldiers were gone.
The black vehicles had disappeared into the night.
Even the street outside looked normal again.
But nothing felt normal anymore.
Broken glass covered the floor.
Coffee cups were shattered near the counter.
The barista stood frozen behind the machine like he had just watched a movie he didn't understand.
Seo-yeon looked around the café and sighed.
"Well."
She pointed at the mess.
"That escalated quickly."
Tae-jun rubbed the back of his neck.
"I'll admit… I didn't expect them to leave that easily."
Dae-hyun leaned against the wall near the window.
"They got what they came for."
Seo-yeon turned toward him.
"And what exactly was that?"
Dae-hyun lifted four fingers.
"Confirmation."
Hae-in spoke quietly.
"Four rings active."
Seo-yeon sighed.
"Yes, we heard the creepy military guy say that."
She looked at the rings again.
"But what does it actually mean?"
Nobody answered immediately.
Because honestly…
None of us fully knew
I looked down at my own hand.
There was no ring on it.
Not like the others.
But something strange was happening inside my chest.
Like a quiet warmth that hadn't been there before.
Tae-jun noticed my expression.
"You feeling it too?"
I frowned.
"Feeling what?"
He pointed at Seo-yeon's hand.
"The gold ring."
Seo-yeon raised an eyebrow.
"What about it?"
Tae-jun exhaled slowly.
"Every time it pulses… something inside me reacts."
Hae-in nodded.
"Mine too."
Seo-yeon blinked.
"…Great."
She held up her hand.
"So apparently I'm a walking battery now."
Dae-hyun chuckled softly.
"Not exactly."
Seo-yeon crossed her arms.
"Then explain."
Dae-hyun stepped away from the window.
His expression had become more serious.
"The rings were never meant to exist alone."
Tae-jun frowned.
"What do you mean?"
Dae-hyun looked at each of us.
"One ring is an artifact."
He pointed toward Hae-in.
"Two rings are coincidence."
Then toward Seo-yeon.
"But four rings together…"
He paused.
"That's an event."
Seo-yeon blinked.
"…That sounds bad."
Dae-hyun shrugged.
"It depends on who you ask."
Hae-in looked thoughtful.
"My grandmother used to say something similar."
Seo-yeon turned toward her.
"Wait, your grandmother too?"
Hae-in nodded.
"She told me the rings were… pieces of something."
Seo-yeon frowned.
"Pieces of what?"
Hae-in shook her head.
"She never finished the story."
Tae-jun sighed.
"I'm starting to hate grandmothers in this story."
Seo-yeon suddenly snapped her fingers.
"Wait."
We all looked at her.
"The journal."
My chest tightened slightly.
Seo-yeon's grandmother's journal.
The one she mentioned earlier.
Seo-yeon pulled out her phone.
"I took photos of some pages before leaving the house."
Dae-hyun's eyebrows lifted slightly.
"Smart."
Seo-yeon smirked.
"I know."
She began scrolling through her gallery.
"There were a lot of weird drawings… symbols… dates…"
Then she stopped.
Her expression changed.
"…Wait."
Tae-jun leaned closer.
"What?"
Seo-yeon zoomed in on one of the photos.
Then slowly turned the screen toward us.
It was a page from the journal.
Old handwriting.
Faded ink.
And a drawing.
Seven rings.
Arranged in a circle.
In the center of the circle…
There was something else.
Not a ring.
Something larger.
Something shaped like a key.
Hae-in whispered,
"…What is that?"
Seo-yeon shook her head.
"No idea."
Dae-hyun leaned closer.
His expression had changed.
"That shouldn't be there."
Seo-yeon blinked.
"You've seen this before?"
Dae-hyun nodded slowly.
"Yes."
Tae-jun crossed his arms.
"And?"
Dae-hyun pointed to the center of the drawing.
"That symbol was never in the original diagram."
Seo-yeon frowned.
"What original diagram?"
Dae-hyun hesitated.
For the first time since we met him…
He looked uncertain.
"The one the military found."
The room went silent again.
Seo-yeon's voice dropped.
"You mean… they had this journal."
Dae-hyun nodded.
"For a while."
Tae-jun narrowed his eyes.
"Then someone stole it."
Dae-hyun looked at him.
"Yes."
Seo-yeon crossed her arms.
"And let me guess."
She tilted her head.
"That someone was you."
Dae-hyun smiled slightly.
"Maybe."
Seo-yeon groaned.
"I knew it."
But Hae-in was still staring at the phone screen.
Her eyes focused on the center symbol.
"The key…"
Seo-yeon looked at her.
"What about it?"
Hae-in pointed at the drawing.
"It's not just a key."
Tae-jun leaned closer.
"Then what is it?"
Hae-in swallowed.
"…It's a lock."
Seo-yeon blinked.
"Locks and keys are literally opposites."
Hae-in shook her head.
"No… I mean the rings form the key."
The room went silent again.
Seo-yeon slowly turned back to the drawing.
Seven rings around the center symbol.
"…You're saying the rings unlock something."
Hae-in nodded.
"Yes."
Tae-jun sighed.
"And the military wants them."
Dae-hyun's voice became quiet.
"They're not the only ones."
Seo-yeon looked up.
"…What do you mean?"
Dae-hyun looked toward the dark street outside again.
Like he was expecting something.
"The rings were lost for centuries."
He continued slowly.
"But there were always… people searching for them."
Tae-jun frowned.
"Collectors?"
Dae-hyun shook his head.
"Believers."
Seo-yeon raised an eyebrow.
"That sounds worse."
Dae-hyun nodded.
"It is."
Before anyone could respond—
My phone vibrated suddenly.
The sound made everyone look at me.
I pulled it out slowly.
Unknown number.
Seo-yeon frowned.
"Answer it."
I hesitated.
Then pressed the button.
"…Hello?"
For a moment—
Only silence answered.
Then a voice spoke.
Distorted.
Mechanical.
"Sergeant Kang Ji-hoon."
My grip tightened on the phone.
"Who is this?"
The voice ignored the question.
"You activated the rings."
Tae-jun's eyes narrowed.
Seo-yeon leaned closer.
The voice continued.
"That means the countdown has started."
My chest tightened again.
"What countdown?"
A quiet pause.
Then the voice said something that made the entire room freeze.
"Three more rings."
Hae-in whispered,
"…Seven."
The voice continued calmly.
"When the seventh ring awakens…"
Seo-yeon held her breath.
"…the gate will open."
My pulse quickened.
"What gate?"
The voice answered softly.
"The one your grandmother tried to seal."
Seo-yeon's eyes widened.
"Who are you?!" she shouted.
But the call ended.
The screen went dark.
For a long moment—
No one spoke.
---
Finally Tae-jun exhaled.
"Well."
Seo-yeon slowly lowered her phone.
Her eyes were still on the drawing in the journal.
Seven rings.
A key.
A lock.
A gate.
Her voice was barely a whisper.
"I think…"
She swallowed.
"…we just found the page my grandmother never finished."
Outside the café…
Thunder rolled quietly in the distance.
And somewhere in the city—
Another ring might already be waking up.
