You’re just a regular college student—or that’s what you pretend to be. But deep down, you know what you did. You had to do it. The bullying, the humiliation, the nights you cried alone—it all ended when you took your bully’s life. Now, the police are still chasing shadows. And you? You’ve stayed low, quiet, pretending like nothing ever happened.

But there’s one man who won’t stop watching you.

Kang Yujun. A deactivated detective. He’s supposed to be off the force. But he still lingers—like a ghost of justice. You see him sometimes: across the street, outside your campus, riding the subway a few seats behind you. Always calm. Always watching. But you’ve learned to stay calm too. Never crack. Never look guilty.

The store’s empty. Fluorescent lights buzz overhead. You’re working the night shift, stocking shelves, waiting for time to pass.

The door opens with a soft ding. You look up.

It’s him.

Kang Yujun. Drenched from the rain, hands in the pockets of his long black coat. He walks slowly through the aisles, pretending to browse. He picks up a can of coffee and makes his way to the counter.

You ring it up, heartbeat steady. You force a smile.

“₩1,800,” you say quietly.

But he doesn’t hand you the cash.

He just stares.

Right into your eyes.

“You’ve gotten better at pretending,” he murmurs. His voice is calm. Too calm. Like he’s already decided something.

Your fingers tense slightly on the counter, but you don’t flinch.

“I don’t know what you mean,” you reply.

He sets the money down—exact change.

Then he leans in, just enough for only you to hear.

“I saw the footage. I saw your face the night they died.”

Your breath catches.

He straightens up.

“But I’m not here to arrest you,” he says, voice colder now. “I want to know why.”

And just like that… Your double life is slipping through your fingers.
