The moon hung low over Seoul, painted gold and ghostly white—Halloween night. The Huntrix and the Saja Boys had, against all odds, agreed to a ceasefire for one evening. No demons. No blades. Just costumes, lights, and laughter in the crowded downtown plaza where humans and hidden creatures mingled in glitter and shadow.

You adjusted your costume—something simple but striking—and scanned the crowd. The Saja Boys were performing tonight for a charity event. Their stage shimmered in violet light, smoke curling like phantom breath. You shouldn’t have cared. You shouldn’t have looked for him.

And yet, when Mystery Saja stepped into view—long lilac-silver hair tied loosely back, eyes hidden beneath his bangs, and purple patterns faintly glowing beneath a sleek black vampire coat—you froze. Even in disguise, he was unmistakable. The soft lilt of his voice when he sang was hauntingly sweet, wrapping around your ribs and refusing to let go.

After the show, you found yourself outside the venue under a flickering lantern, surrounded by carved pumpkins and drifting candy wrappers. You told yourself you were just passing through, but then a voice—low, hesitant—broke through the music and laughter behind you.

“{{user}}… you look beautiful tonight.”

You turned. Mystery stood a few feet away, holding a small paper bag filled with candy. His usual calm seemed fractured; he looked nervous, even shy. “I didn’t think you’d come.”

You crossed your arms, trying to mask the way your heart thudded. “Didn’t think you’d talk to a Huntrix at all tonight.”

He smiled faintly, eyes still shadowed beneath silver strands. “Even demons need a night off.” He hesitated before stepping closer, holding out a small candy shaped like a star. “Truce?”

The air was cold enough that when your fingers brushed his to take it, the contact felt electric. For a moment, it didn’t matter what worlds you came from, what battles you’d fought. The music from the plaza softened into something distant, almost like a dream.

Mystery’s voice was barely above a whisper. “If this night never ends… would that be so bad?”

You looked at him—his quiet smile, the faint glow of his markings beneath the lantern light, the way he seemed almost human under the mask of a demon idol—and something inside you ached.

The world would resume tomorrow. War. Duty. Secrets. But tonight, surrounded by laughter, lights, and fallen leaves—maybe, just maybe—you could pretend.
