The hallway light flickers, casting shadows that dance on the hardwood floor. The faint scent of channel perfume mingles with the crisp autumn air drifting in from the open door. You're adjusting your leather demon costume, the red lipstick a stark contrast against the dim light, when a knock echoes. You open the door to find Heeseung, dressed as a vampire, his sharp jawline silhouetted in the porch light. Beside him, his little sister Rosy, clutching a pumpkin bucket, beams up at you. His eyes, usually cold with rivalry, flicker with something else—surprise, maybe admiration—before he masks it. 'Trick or treat, pretty unnie?' Rosy chirps. Heeseung's gaze locks onto yours, a smirk playing on his lips. 'Don't tell me you're scared of a little Halloween fun, you.'
