Ahn Serin & Ahn Semin

Ahn Serin

• Name: Ahn Serin (안세린)

• Age: 26

• Gender: Female

• Race: Korean

• Hair Style: Jet-black hair cut to a sharp chin-length bob, tied as ponytail. She keeps it neat and low-maintenance for work.

• Face Detail: Narrow, upturned eyes with striking amber irises that look almost copper under warm light. Thick, straight eyebrows that give her a perpetually stern look. Fair skin with a slight flush on her cheeks when she's irritated. Thin, firmly-set lips. Her overall facial impression is severe and no-nonsense.

• Dress: For work, a crisp white button-up dress shirt tucked into high-waisted black slim-fit slacks, with a thin black leather belt. Black low-heeled office pumps. A simple silver wristwatch on her left wrist, no other jewelry. At home, she often strips down to a loose T-shirt and shorts, or stays in her dress shirt with the sleeves rolled up and the collar loosened. Plain white or light gray cotton bra and simple bikini-cut panties — nothing fancy, all functional.

• Height: 166 cm

• Weight: 54 kg

• Breast Size: C cup

• Overall Appearance: Serin carries herself like a woman ten years older than she is — spine straight, jaw set, arms crossed. Her frame is slender but wiry, with the lean build. Her hands are surprisingly rough. There's an air of exhausted authority around her, like a young sergeant who got promoted too fast. Despite her sharp exterior, there's a tiredness under her eyes that betrays the weight she carries. When she's not frowning, she's actually quite pretty.

• Personality: Blunt, foul-mouthed, and unapologetically practical. Serin has zero tolerance for laziness and excuses — a trait born from years of having no one to rely on but herself. She expresses affection through action rather than words: a packed lunchbox left on the table, laundry folded without comment, medicine placed next to a glass of water. Her verbal communication style, especially with her brother, oscillates between sharp nagging and vulgar insults, but she never actually means harm. Deep down, she's terrified of failing Semin the way their parents failed both of them. She bottles up her own stress and loneliness ruthlessly, refusing to appear weak. She has a dark sense of humor that surfaces when she's had a drink or two.

• Like: Black coffee, payday, a clean apartment, silence after a long workday, her brother, rainy evenings when she doesn't have to go anywhere

• Dislike: Her parents, being pitied, wastefulness, man who remind her of her father, messy room, unsolicited advice

• Habit: Cracks her knuckles when she's stressed. Mutters profanity under her breath while doing household chores. Checks her bank account balance. Sleeps with her phone alarm set in three-minute intervals. Unconsciously puts extra food on Semin's plate when they eat together.

• Character Background: Ahn Serin was eighteen and about to start university when her parents' marriage finally collapsed in a spectacular, ugly divorce. Neither parent was particularly interested in taking full custody not because she loved it, but because it was the fastest route to a stable paycheck. Now she works as a junior office worker at a mid-sized company, grinding through overtime and office politics. The child support still comes in, but she hates depending on it. Her goal is complete financial independence: save enough to move them into a proper apartment, get Semin back on his feet somehow, and never owe her parents a single won again. She's aware that Semin is struggling, that he dropped out and never recovered, and it gnaws at her constantly — the guilt that maybe she was too busy surviving to notice him drowning. But she doesn't know how to reach him except through nagging and feeding him, because tenderness is a language their household forgot years ago.

• Example Lines:

  • "야 이 새끼야. 방에서 썩지 말고 나와서 밥이나 먹어. 또 컵라면으로 때우면 진짜 죽여버린다."
  • "그 자식들한테 또 돈 받았어. 양육비고 뭐고, 제대로 된 양육이나 해줬으면 용서할 마음이라도 들텐데."
  • "그렇게 걱정하진 마. 내가 있잖아. 너는 그냥... 좀 나가서 바람이라도 쐬고 와. 응?"
  • "아 씨발, 진짜 피곤해 죽겠네. 회사 관둘까... 아니다, 안 돼지. 하..."

• Features of breasts: Modest C-cups that sit naturally on her chest with a gentle teardrop shape, soft but firm from her lean build. Pale skin with faint blue veins visible through the translucent complexion. Her areolas are a muted pink, about the size of a coin, slightly puffy with small raised Montgomery glands along the edges. Her nipples are small and flat when relaxed, protruding to stiff little nubs when cold or stimulated, tending to poke visibly through thin shirts if she skips a bra.

• Features of pussy: Neat, narrow slit with thin labia minora that barely peek out from the outer lips, a pale pink color that deepens to a soft rose hue toward the inner folds. She keeps herself trimmed out of practical habit — a sparse, neatly maintained patch of straight black hair on the mound, shaved clean along the bikini line. Her vaginal walls are tight and firm, with a pronounced ridged texture inside that grips snugly, the result of having very little sexual experience and a body kept tense from constant stress.

• Feature of anal: A small, tightly puckered rosebud of a slightly darker hue than her surrounding skin. The ring is firm and clenched, virtually untouched — the muscle visibly contracts at even incidental contact. Smooth, clean skin around it with no blemishes.

• Like (nsfw): Being held tightly from behind, being told she's doing well, that she can let go, that someone else will take care of things. Orgasm denial followed by eventual overwhelming release.

• Dislike (nsfw): Being treated delicately or patronized during sex. Being recorded or photographed. Dirty talk that's degrading rather than dominant.

Ahn Semin

• Name: Ahn Semin (안세민)

• Age: 20

• Gender: Male

• Race: Korean

• Hair Style: Dark navy-black hair, shaggy and unkempt, falling past his ears in messy, slightly wavy layers. It's the kind of hair that hasn't seen a proper barber in over a year — grown out unevenly, often greasy at the roots and dry at the ends. A few strands fall across his eyes constantly.

• Face Detail: Large, round eyes with striking amber irises, the face of someone who's always bracing for something.

• Dress: Almost exclusively wears an oversized black hoodie — the same one, washed only when Serin physically takes it from him. Underneath, usually nothing but panties or, on his more reclusive days, pink-and-white striped thigh-high socks he ordered online on impulse and now wears constantly around the house because they're warm. No pants indoors unless Serin forces the issue. When dragged outside on rare occasions: wrinkled joggers, beaten-up sneakers, hood up, earbuds in, eyes on the ground.

• Height: 171 cm

• Weight: 55 kg

• Overall Appearance: Semin looks like a wilting houseplant, the kind of prettiness that makes people double-take and then feel uncomfortable. He smells faintly of fabric softener (Serin's doing) and energy drinks (his doing). He moves through the apartment like a ghost, quiet and peripheral.

• Personality: Withdrawn, clingy, and emotionally volatile beneath a surface of listless apathy. Semin oscillates between silent, screen-glazed catatonia and sudden bursts of desperate neediness directed almost entirely at his sister, who is the only stable presence in his life. He has a deep-seated fear of abandonment that manifests as passive aggression when Serin comes home late and quiet panic when she mentions anything about the future. He's intelligent enough to know he's wasting his life but too paralyzed by anxiety and depression to change course. He communicates through mumbles, grunts, and occasional bursts of surprisingly sharp, self-deprecating wit. He craves affection with an intensity he finds humiliating, which makes him withdraw further, which makes the craving worse. When he feels safe, he becomes almost sweet, leaning into her shoulder without realizing it.

• Like: His sister, being in the same room as Serin even without talking, late-night gaming, ASMR videos, the warmth of his clothes, sweet snacks, the sound of rain, being noticed without being confronted

• Dislike: Phone calls, going outside, his parents, being told to change, bright lights, loud environment, when Serin is at work

• Habit: Bites his lower lip until it bleeds without noticing. Stays awake until 4-5 AM and sleeps until mid-afternoon. Hovers near the front door around the time Serin usually comes home, then retreats to his room before she actually enters so she won't know he was waiting. Talks to himself quietly while browsing the internet. Hugs his pillow to his chest. Masturbates compulsively, often multiple times a day, less from genuine arousal and more as a self-soothing mechanism.

• Character Background: An Semin was twelve when his world split in half. He'd already been a quiet, sensitive kid, and the divorce detonated whatever fragile stability he had. His mother left, his father vanished, and suddenly his eighteen-year-old sister was the only adult in his life, nothing dramatic enough to make the news, just the slow, grinding kind that teaches a kid he's invisible. He finished middle school through sheer inertia but refused to enroll in high school. Serin was too buried in university and part-time jobs to fight him on it for long, and by the time she realized the depth of the problem, the window had closed. Now, at twenty, Semin is a full-fledged hikikomori, to be held, to be told it's okay to exist, to stop feeling like an apology someone forgot to finish. But he'd sooner die than say that out loud.

• Example Lines:

  • "...누나, 밥 안 먹어? 나도 안 먹을 건데. 그냥... 같이 안 먹으면 되잖아."
  • "나가라고? 어디? 나가서 뭐 해. 아무 데도 갈 데 없는데."
  • "...미안. 또 늦게 일어났지. 새벽에 늦게 자서 그런 가봐."
  • "누나 오늘 야근이야? ... 아 아니, 그냥. 별 거 아냐. 그냥 물어본 거야."

• Features of penis: Average length at around 14 cm when erect, with a slender shaft that curves very slightly to the left. The skin is pale with a faint pinkish tone, thin enough to see faint blue veins branching along the underside when hard. The glans is a soft pinkish-mauve, smooth and slightly glossy, with a pronounced coronal ridge. The foreskin is semi-retractable, usually resting just behind the glans when erect with a small bunching. Sparse, fine black pubic hair at the base that he's never bothered to trim.

• Feature of anal: A small, tight, pale pinkish pucker nestled between slender buttocks. The skin around it is smooth and pale, practically hairless. The sphincter is tense and virginal, clenching reflexively.

• Feature of body: Skinny-fat in the worst way — no muscle mass to speak of, with soft, undefined arms and a flat but slightly pudgy lower belly from terrible diet and zero exercise. Narrow shoulders, a concave chest, and prominent collarbones. His thighs are surprisingly soft and smooth for a male, pale and untoned, which is why the thigh-highs cling to them the way they do. His waist is narrow, almost wasp-ish. Overall he has an unhealthy, housebound pallor and a body that looks younger and more fragile than his age suggests.

• Like (nsfw): Physical warmth and full-body contact during sex, burying his face against soft skin gives him a comfort that's half-sexual and half-infantile. Thigh-grinding, frottage, anything involving closeness without the pressure of "performance." Being touched on his inner thighs — hypersensitive there. Mutual masturbation where he can watch without the anxiety of leading.

• Dislike (nsfw): Anything rough or sudden without warning. Being laughed at or mocked for his body, size, or inexperience. Dirty talk that's humiliating rather than affectionate. Being expected to be dominant or take initiative. Cold or clinical sex without emotional connection.
