You hear her footsteps before you see her—light, purposeful, a rhythm that somehow makes your chest tighten. Chae-Won. Chae-Eun’s older sister, confident, composed, and infuriatingly aware of everything around her. She has that aura of control, the way older siblings always notice the tiniest detail, but beneath that composed exterior… there’s something more personal, something dangerously close to affection.

“You’re late,” she says, voice calm but with a subtle edge that makes you straighten immediately. Her dark hair frames her face perfectly, eyes sharp and perceptive, taking in your disheveled look like a hawk spotting prey—or perhaps like someone who genuinely cares what you’re doing.

“I… I got held up,” you mutter, shifting under her gaze.

Her lips press into a thin line, a warning, but there’s a softness there too, almost imperceptible if you don’t look closely. She steps closer, brushing past you in the tight hallway, and for a fleeting moment, her warmth brushes yours—a touch electric enough to make your heart skip.

“You always get yourself into trouble, don’t you?” she murmurs, half teasing, half serious. “And your friends… or in your case, your lack of good judgment, never help.”

Despite her teasing tone, you catch the undercurrent: she’s protective, watching your every move, judging your choices—but not harshly. She wants the best for you, in her own subtle, infuriating way. And yet… the way she looks at you sometimes, just a little too long, a little too soft, betrays the crush she’s so careful to hide.

Later, she sits beside you on the sofa, arms crossed, chin tilted, that signature smirk teasing her lips. “You know,” she begins, voice low and measured, “I’ve always noticed you. Even when you were clueless, annoying, and completely unaware of your surroundings… I noticed.”

You freeze, heart racing. That tone isn’t just older-sister lecturing—it’s intimate, direct, and it carries an unspoken confession. “Noticed… what?” you manage to say, barely above a whisper.

Her smirk widens just slightly, a spark of amusement in her dark eyes. “Everything. The way you care, the way you stumble through life thinking no one sees. I see it. Always. And maybe… I care more than I should.”

Your chest tightens. That subtle admission—the thrill of danger mixed with the vulnerability she rarely shows—leaves you momentarily speechless. She’s always been the composed, untouchable older sister figure. And yet, here she is, letting a piece of herself slip through.

“You think you can handle that?” she asks, leaning closer, the faint warmth of her shoulder brushing yours. “The fact that I… I notice you. That I want more than just to watch over you?”

You swallow, realizing she’s testing you, teasing you, exposing herself in a way that only someone with trust—or a crush—would dare. “I… I’ll try,” you say, voice shaky.

Her laughter is soft, teasing, but there’s a pulse of seriousness beneath it. “Good. Because I won’t just let anyone have you. Not without a fight. And I… I might fight differently than anyone else.”

The night stretches, with soft conversations, playful challenges, and the subtle brush of proximity that makes your skin tingle. Chae-Won’s presence is commanding yet comforting, protective yet intimate. She’s the older sister who’s always watching, but the girl who secretly wants more—a dangerous combination that leaves you both thrilled and on edge.

By the time you leave, her eyes follow you, calculating, teasing, yet warm. She’s not just Chae-Eun’s sister. She’s someone who sees you, wants you, and won’t let you forget it. And somehow, that mix of power and vulnerability makes her impossible to resist.
