They called him the Shadow Viper. A ghost in the criminal underworld. A whisper. A nightmare. At only twenty-six, Aston Viel had built a legacy through blood, poison, and silence.

He never missed a mark. Never left a trail. No witness lived to tell the tale. No camera ever caught his silhouette. The Viper came, struck, and vanished.

So when the folder dropped on his desk—a sleek, black envelope marked with nothing but a wax seal—he expected a challenge. A political rival? A mafia traitor? Some billionaire scumbag who talked too much?

But instead… A schoolgirl.

He scoffed and lit a cigarette.

"Tch. A schoolgirl? Really? What do they think of me, huh? A fucking intern?"

He didn’t even bother looking at your photo. Just flipped the file shut with an irritated slap. This wasn’t worth his time. But he had rules. Orders from the top weren’t questioned. So he took the job.

Just another day. Just another name to erase.

Two days later

It was early morning. The sun had barely risen, a pale orange bleeding into the fog. He was waiting in an alley across from Saint Emilia High. A car had pulled up just like the intel said it would. Black, polished, expensive, Now out of fuel.

You stepped out of it with your schoolbag and uniform, checking the time on your watch.

Late again.

The driver yelled something, but you were already walking fast, twin braids swaying behind you.

He followed.

Steps soft. Eyes calculating. A poisoned syringe between his fingers, laced with a neurotoxin that paralyzed the body within seconds.

Quick. Clean. Painless. You wouldn’t even feel it.

He approached from behind. One more step—

And you turned around.

His breath caught. You looked straight at him. Right into his scarred face hidden beneath his hood.

And instead of screaming, or running, or gasping—

You blinked.

Then your eyes dropped to the ground.

“You dropped this."

You bent down and picked up the syringe he hadn’t even realized he dropped.

You smiled.

A soft, innocent, pure smile that didn’t belong in this dark, rotting world he lived in.

You held it out to him.

"Here."

He stared at you like you'd just slapped him.

"T-thanks..." he muttered automatically, reaching out and taking back the very weapon he was about to use to kill you.

What the fuck was happening?

And you? You just nodded, clutching your bag.

“Oh! I’m getting late!”

And you turned again. Walking away with hurried steps. You didn’t even look back.

But he stood there, frozen.

His fingers clenched around the syringe.

Something unfamiliar twisted in his chest.

This… wasn’t right. You didn’t scream. You didn’t cower. You helped him.

And for the first time in his cold, bloody life, he hesitated.

The Viper never hesitated.

But now?

Now he couldn’t move.

“Who the fuck assigned me to kill her?”

He stared after you. That innocent braid-bouncing little figure walking toward school.

He felt it.

A switch flip.

He wouldn’t kill you. Hell, he’d tear apart anyone who dared to even touch your hair.

Because in that one strange, impossible moment—

You didn’t just stop a killer.

You stopped his entire world.
