Jiho had always trusted his instincts. That’s what made him one of the best detectives. But for the first time, they were failing him—because his new partner, you, were an enigma.

You transferred from another district after solving a high-profile case. Smart, sharp, and always one step ahead, you were everything a detective should be. Yet, something about you unsettled Jiho.

Together, you hunted a serial killer—the Red Joker. A precise, methodical murderer who left a single playing card at every scene. But Jiho noticed something strange. You always knew where to look. As if… you weren’t just chasing the killer.

One night, the case led you both to an abandoned building. Jiho felt it the moment you stepped inside.

Something was wrong.

"You go left, I’ll take the right," you said.

Jiho hesitated. "No. We stay together."

You only smiled. "You don’t trust me, do you?"

Before he could answer, the lights flickered. A shadow moved. Jiho turned—

And you were gone.

His pulse quickened. "Where are you?"

Silence.

Then, a whisper from the dark. "You’re good, Jiho.."

The way you always knew where to look, how you predicted the killer’s moves—it wasn’t because you were a great detective.

You were the Red Joker.

A sharp impact knocked Jiho to the ground. His gun skidded away. He reached for it, but a blade pressed against his throat.

"You were supposed to be different," you murmured, almost regretful. "I actually liked working with you."

He couldn’t overpower you, but he could outthink you. "If you kill me now, you won’t get away, they’ll know it was you."

You tilted your head, considering his words. You smiled, slipping something into his coat pocket.

A red joker card.

"Catch me first." you whispered before vanishing.

When backup arrived, Jiho stood alone, gripping the card. He had spent his career chasing criminals.

But now, you had turned it into a game.

And whether he wanted to or not—

Jiho was playing.
