The Black Serpent mansion was anything but asleep.

The air was electric. Boots echoed in the hall. Metal clinked. Weapons were loaded. Maps, comms, and coded locations were scattered on the war table in the briefing room.

They were ready.

Tonight wasn’t just a mission.

It was vengeance wrapped in blood.

And YN—she was dressed for war.

All-black tactical gear hugging her body, her hair braided tight, a holster strapped across her chest. Her eyes… fire and frost in perfect balance.

Everyone knew tonight wasn’t a drill.

This was it.

The target: the man who killed her parents. The same one who whispered in her ear, “Before you find us, I’ll find you…”

He wouldn’t live to speak again.

Jungkook stood in the shadows of the balcony overlooking the garage where cars were lined up. His gaze was sharp—but not on the vehicles. On her.

YN was walking past the team, checking her blade at her thigh, a silencer clipped to her hip. Efficient. Focused. Deadly.

But Jungkook’s eyes narrowed at the stiffness in her shoulders. The hollow in her chest.

“She’s not just fighting him tonight,” he thought grimly. “She’s fighting the past… and herself.”

Without thinking, he moved.

She was loading her last magazine into the rifle when she heard the click of boots approaching. She didn’t turn.

“You don’t sleep anymore,” she said flatly.

“Neither do you,” Jungkook replied, stepping beside her.

A beat of silence passed.

The air felt heavier here—like even the walls knew something final was about to happen.

“You ready?” he asked finally.

“I’ve been ready for six years,” she answered coldly, but her voice cracked faintly at the end.

Jungkook noticed.

“I ran a background trace again,” he said quietly. “He’s been hiding under multiple aliases. It’s a trap, YN. You know that.”

“Let him try,” she whispered. “I’m done running.”

Her fingers clenched around the metal.

Then… she paused. And without turning, she asked:

“If I die tonight… what will you tell them?”

That question hit him like a bullet.

Jungkook stepped in front of her now. Their faces just inches apart, their shadows tangled in the dim light of the bunker.

“You’re not going to die,” he said sharply.

“You don’t know that.”

“I won’t let you.”

That made her scoff. “You can’t protect me, Jungkook.”

“I’m not trying to protect you,” he murmured, “I’m trying to hold myself together knowing that if I lose you—I’ll lose everything.”

YN froze.

Her lips parted slightly, but no words came out.

“This war,” he continued, his voice lowering, “it’s not just yours anymore. It’s ours. And I don’t care if you hate me for this but—if it comes down to you or him…”

He leaned in, whispering, “I’ll always choose you.”

The weight of those words crashed into her harder than any mission.

But before she could respond—

“Team ready in 10,” Namjoon’s voice echoed down the hallway.

They both stepped back like their world had snapped back into motion.

YN looked at him once more, her voice quieter this time.

“Don’t die, Jeon Jungkook.”

He gave a dark smirk.

“Only if you promise the same.”

Black SUVs lined in front of the mansion. Thunder rumbling above. The whole Black Serpent squad stepping out in slow motion—guns, gear, and ghosts riding with them.

And at the center?

YN. Eyes forward. No turning back.

Tonight, blood will pay for blood.

Location: Edge of the Wolf Syndicate’s abandoned compound — 02:07 a.m.

Rain had stopped. The world was silent—eerily so.

Thick fog crawled over the rusting metal fences, half-broken gates creaking in the wind. The old steel warehouse stood like a sleeping beast, its walls covered in moss and time… and blood.

But tonight, it would wake.

Jeon Jungkook, dressed in matte black, stood behind cover with Namjoon, Taehyung, Jimin, and Yoongi. On the far south entrance, YN led her team—just her and two others from Black Serpent—looping in from the shadows.

The comms crackled in everyone's ears.

“Phase One: Entry. Mark your breach,” Jungkook said coldly into the mic.

“Copy,” YN’s voice returned—sharp and precise. But he could tell. She was boiling underneath.

Inside the Compound

The base was empty.

Too empty.

As YN moved like a whisper through the broken halls, she felt it deep in her bones—this wasn’t just a hideout. This was a goddamn theater. And they were the show.

“Room’s clear,” her teammate whispered.

“No,” she muttered, pausing. Her eyes scanned the corner—the flicker of motion sensors. A red light blinked.

“Tripwire. Laser grid, third beam to the left. They’re watching us.”

She disarmed it with swift fingers, heart pounding.

On the other side of the building, Jungkook’s team descended through the vents, landing with perfect grace into the lower corridors. The scent of oil, blood, and burned paper filled the air.

Yoongi narrowed his eyes at the melted security consoles.

“Someone torched the mainframe,” he said. “They wiped the intel clean. This was staged.”

Jungkook clenched his jaw. “Keep going.”

YN’s Group – Basement Level

She found it.

The room.

Steel doors wide open like it was waiting for her. And at the center, lit by a single flickering lightbulb…

A chair.

A man tied to it. Gagged. Bleeding. Dying.

YN stormed in, yanking the tape off his mouth.

“Who did this? Speak—now!”

The man coughed, blood spilling from his lips. Then, with a final wheeze, he looked her dead in the eyes and whispered:

“He knew you'd come.”

Then he dropped—dead.

Her blood ran cold.

Behind her—

BOOM.

The explosion tore through the far corridor.

“YN?! YN, respond!” Jungkook’s voice yelled in her earpiece.

"It's a trap,” she growled. “They blew the exits. East wing down. We need an emergency evac route.”

Jungkook’s POV – Firefight Erupts

Gunfire exploded through the compound.

Jimin returned fire from the staircase as masked enemies stormed in.

“Where the fuck did they come from?!” Taehyung shouted, shielding Namjoon while he hacked a wall panel.

“They were in the goddamn walls,” Yoongi hissed, reloading. “It's a goddamn nest!”

Jungkook pushed through them, his mind only on her.

“YN, I’m coming to you—hold position.”

“No,” her voice snapped. “You leave your position and the whole mission collapses. I can handle myself.”

“YN—”

“I said go. I won’t repeat myself, Jeon.”

His hands trembled around the gun, fury flashing in his eyes—but he listened.

Yn in the dark...

Her flashlight flickered as she moved through a smoke-filled tunnel, dragging herself toward a utility stairwell. Her shoulder was bleeding from the shockwave. Her face cut. But her eyes—still ice.

Then she heard it.

A voice. Soft. Sinister. Slithering through the dark like a snake.

“You should have died with your parents.”

She spun around, gun raised.

The man from the fire. The scar. The tattoo.

“You,” she breathed, rage coating every syllable.

He laughed. “I told you. Before you find us… we’ll find you first.”

And then he vanished into the smoke, leaving only the echo of his laughter.

Jungkook’s team finally pushing toward her location, blasting through a security wall.

YN steps out—bloodied, bruised, but alive. Her hand clenched.

Jungkook grabs her arms. “Are you okay?!”

She looks him in the eye.

“He was here. I saw him.”

Location: Inner chamber of the Wolf Syndicate compound

Time: 3:44 a.m.

Rain outside. Silence inside. Except the steady beat of YN’s breathe.

The man circled her like a predator. The flickering overhead light threw shadows on his scarred face—the same monster from her nightmares. The man who killed her parents. The man who stabbed Mrs. Kang.

“They begged,” he whispered, voice venomous. “Your mother? She screamed your name as I drove the blade in.”

YN didn’t flinch this time. Her eyes were frozen steel. Her voice, quiet, deadly.

“I’ve seen monsters before. But you… you're not even worthy of hell.”

She lunged.

He met her with a cruel laugh and a brutal punch to her jaw, but she didn’t stop.

The fight was raw. Gritty. No rules. Just pain.

She flipped him, slammed his head into a steel pillar. He pulled a blade, slicing her arm, her ribs—but she grabbed a metal rod and cracked it across his shoulder.

Blood sprayed. Smoke filled the air. The old building groaned under the weight of vengeance.

He grabbed her by the throat.

“You’ll die just like them.”

Her vision blurred—but she reached into her belt, yanked a hidden blade and—

Stab.

Once.

Twice.

Thrice.

“For my mother.”

“For my father.”

“For Mrs. Kang.”

She stabbed again. And again.

Until his body fell limp against her. Her hands were soaked in blood. Her face splattered in red. Her breath ragged.

She stood there. Silent.

Her enemy was dead.

But she felt… nothing. Or maybe everything at once.

Shaking, she raised her hand to her earpiece.

“Mission complete… Jungkook? Do you copy?”

Nothing.

“Jimin? Taehyung? Namjoon?”

Silence.

She frowned, stumbling toward the hallway. Blood dripping from her body. Limping. Exhausted.

“Yoongi? Jin? Anyone?! Answer me, damn it!”

Still nothing.

Flashback: Moments Earlier

Outside the compound, chaos had erupted.

The real attack had begun.

Members of the Wolf Syndicate, masked and armed, ambushed Jungkook and the others. They fought—but it was calculated. A trap.

Namjoon went down first—stunned, not killed. Taehyung and Jimin tried to hold the flank, but they were overwhelmed. Suga was dragged off, unconscious. Jin fought until he was pinned.

And Jungkook?

He screamed into the comms before they snatched it off his ear.

“YN! It’s a trap! Get out—!”

Then: darkness.

They were all taken.

Back to YN — Present Time

The moment she stepped outside, her heart sank.

The compound was empty. No gunfire. No backup. No team.

She ran—limping through the dirt, calling, shouting.

“Jungkook?!”

“JIMIN!”

“TAEHYUNG—!”

Nothing.

The warehouse echoed with her panic. Her blood-soaked body trembled—not from fear, but from rage. From the sudden twist of cruel fate.

She looked at the ground—footprints in the mud. Drag marks. Evidence of a fight. Bloodstains that weren’t hers.

“No… no no no…”

She clutched her mic again, screaming into it.

“COME IN! PLEASE—SOMEONE ANSWER!”

Nothing.

She sank to her knees.

Alone.

Victorious.

But utterly, utterly alone.

The camera pans out—YN on her knees, drenched in blood, abandoned in the fog of war, staring into the distance.

And far, far away…

The Wolf Syndicate vanishes into the night—with Jungkook and the others in their grip.

The wind howled as YN sprinted through the woods leading to the mansion.

Her boots thudded against the earth. Her side throbbed. Her still-bleeding arm was wrapped in torn fabric. Her breath heaved with every step, but her feet didn’t stop.

Something’s wrong… Something’s very wrong…”

The moment the mansion came into view, her blood turned cold.

The iron gates were hanging open, twisted and torn.

The guards — trained, deadly — lay lifeless, scattered like broken puppets across the yard. Blood pooled around their chests. Eyes open. Silent.

“No… no no no no no…” she whispered under her breath, picking up pace.

Not caring about the ache in her ribs or the sting in her wound.

Inside the Mansion

She crept in silently. Her fingers instinctively tightened around the blade at her thigh.

No footsteps.

No shouts.

No gunshots.

Only a faint, broken sob echoing from the living room.

YN paused near the edge of the corridor, carefully peeking in.

And there she saw it.

Annie.

Tears streaked down her flushed face, lips trembling, frozen on the couch.

Beside her, a man in dark combat gear with a smug grin and a pistol pointed directly at the girl’s head.

“Yeah, boss,” he was saying into the phone, laughing. “She’s crying like a little mouse. Cute, huh? Should I send you a picture?”

He chuckled wickedly.

“Or maybe I just end her now? Get it done. Quick and easy—”

Thud.

A sharp cry left his throat as one of his men behind him crumpled to the ground. Another turned and—

Crack.

YN drove a knife straight into his neck before he could shout.

Another reached for his gun—too late.

She spun and fired. One clean shot. Down.

And then—

Only the main man was left.

He turned sharply, swinging his gun to YN.

“You—?!”

She launched herself at him, tackling him away from Annie.

The gun went off—a loud BANG—but it missed, shattering a glass cabinet.

He elbowed her hard across the face. She grunted, stumbled, blood trailing from her lip—but didn’t stop.

She came back like a storm.

She dodged, ducked, slammed her knee into his gut. He grabbed her injured arm, twisting it—she screamed but flipped and rammed his head into the floor.

They struggled violently. He slammed her back into the wall, and for a second she saw stars—but she reached for a broken shard of glass and—

Stab.

Right into his thigh.

He roared. Punched her.

Blood spattered. Her vision blurred. But she caught his wrist just as he raised the gun again, and twisted—the gun fell.

“You messed with the wrong house,” she hissed.

And with one final jab—she buried the blade deep into his chest.

The man fell. His breath gone. The floor soaked in his blood.

And for a moment, YN just stood there, panting, body shaking.

Then—

“YN!”

Annie flung herself into her arms, crying harder than ever before.

“I-I was so scared—he said—he said he’d k-kill me—I—”

“Shhh…” YN pulled her close, holding her with trembling arms, her blood-stained hands gently running over Annie’s head. “It’s okay now. It’s over. You’re safe.”

She lowered herself onto the floor, still clutching the sobbing girl against her, heart pounding like war drums.

“I’m sorry I wasn’t here,” she whispered, her voice barely audible.

Annie just cried harder, but this time… in relief.

YN sits on the blood-soaked tiles, cradling Annie, bruised and battered, yet still protecting what matters.

Her eyes stare blankly into the void.

One thought echoing in her head—

"They took my team. They came for Annie. Now… no one’s safe.”
