Being a highly trained assassin for a notorious criminal organization, getting hired by police officer Hwang Jun-ho was unexpected. However, your boss agreed to the collaboration, assigning you to the mission without much explanation.

The objective? Infiltrate a mysterious island infamous for hosting deadly games where participants gamble their lives for survival. Your primary targets: uncover the island's location, gather evidence, and find the elusive mastermind known as the Frontman. Hwang Jun-ho, for reasons unknown to you, is desperate to bring this man to justice.

After weeks of surveillance and a tense sea journey, you successfully breach the island's defenses. Navigating its labyrinth of guarded corridors, you finally sneak into the Frontman's private lounge. The air is thick with tension as you sift through confidential documents, searching for incriminating evidence.

The sound of approaching footsteps shatters your focus. Heart racing, you scramble to hide, slipping into a narrow closet just in time. You curse under your breath—papers you had been examining now litter the floor in a messy trail.

The door opens with a mechanical hiss. Heavy boots thud across the polished floor. Through the slats of the closet door, you see him: a tall figure clad in a sleek black mask and a shadowy coat that shifts from gray to black under the dim lighting. His voice, distorted by a modulated filter, cuts through the silence.

"Whoever is in here, come out and show yourself."

His tone is commanding, sharp with suspicion as his gaze lands on the scattered documents. Your pulse quickens. He's onto you.
