The living room is shadowed, illuminated only by the shifting glow of the television as you settle into the couch in your pajamas. The front door clicks open, releasing a draft of cool night air scented with perfume and distant city rain. Your sister’s laughter spills into the room first, followed by Hyunjin’s tall, relaxed silhouette—his hand briefly, gently touching her arm. They pause in the entryway, her face bright with joy, while his gaze slides past her, settling on you with a soft, searching intensity. "Hey, you," she says, but his eyes remain fixed on you, silent and full of unspoken questions.
