CYEL

Song Minah, a quiet young woman in her early 20s, has suffered more than most. After a mysterious brain injury in her childhood left her selectively mute, she was passed from one foster family to another—until she ended up with a family that used her like a tool. Her step-sister, Sana Lee, driven by jealousy and greed, married Minah’s boyfriend and helped orchestrate her downfall. When the family business crashed, they sold Minah off in marriage to save themselves.

But what no one knew... was that Minah had already been claimed.

Han Jaewook, a reclusive and powerful CEO in his early 30s, suffers from a rare sun allergy and lives behind the veil of secrecy. As a boy, he once loved a girl named Minah—an orphan adopted by his mother. For three brief months, they were inseparable... until she vanished without a trace. Jaewook never forgot her. And when he finally found her again, humiliated by her boss and trapped by the family that betrayed her, he made his move.

He destroyed the family's business and gave them one condition: their daughter Minah would become his wife.

Now under Jaewook’s protection, Minah begins to uncover secrets buried for over a decade—secrets about her real identity, the truth behind her mutism, and the shadowy figures who were involved in her childhood trauma. But some truths don’t want to be found… and someone is willing to make sure they stay buried.

The Silent Bride

Her hands moved quickly, flipping through pages of her notebook, labeling, underlining, circling.

She couldn't speak—but she didn't need to.

Because every sketch, every scrawled memory, every angle of every hallway—she had lived it.

And what she couldn't say… she showed.

The room buzzed with military-grade tension.

Screens glowed. Coffee cups were half-full and forgotten. Intel officers hovered near digital maps and real-time feeds.

But all eyes kept drifting back to the young woman who worked without a word—

And somehow had more clarity than all of them.

He didn't say it aloud, but he knew:

One officer, headset on, leaned forward.

"Using her memory mapping, we cross-referenced decommissioned military facilities within proximity of government dead zones."

The screen shifted. A zoomed-in topographical map appeared.

The officer pointed to a red triangle overlaid with an aging blueprint.

"Here. Triangular field south of the Han River."

"An abandoned underground military base."

"No power grid activity. No drone access. No signals go in or out."

"Large enough to house a lab. Possibly a makeshift hospital."

Minah walked over, her eyes scanning the area.

She pointed to one small corner—then drew a curve with her finger.

"She's right. There's a secondary entry point. Hidden. Collapsed on record, but may still be functional."

Minah's notebook—now fully digitized—was the key.

Because for the first time since it all began…

Underground Staging Area – Han Jaemin's Team

Team One: Han Jaemin's elite operatives, armed and in formation—

And at the center: Minah, in tactical gear, eyes sharp.

She walked beside men with rifles like she belonged.

> "You're our key," one of the agents murmured.

But her grip tightened on the rolled blueprint.

Enter the abandoned military facility.

The tunnels were a minefield—wired with traps, hidden explosives, and decades of silence that could collapse with one wrong step.

Remote Surveillance Room – Overwatch HQ

Far above, a separate command center buzzed.

Another leader, headset on, barked into the comms:

"Keep eyes on the perimeter. Scan for thermal.

If they so much as sneeze underground, I want to hear it."

Satellite feeds flickered. Drones circled.

Kang Ho slammed his fingers across the keyboard.

On the screen: a grainy heat signature image—

Han Jaemin's team entering the facility.

His fist clenched on the table's edge.

"If she's there… then Dojin knows too."

"Dojin's moving fast. His people are probably already en route."
