GENERAL INFO

Name: Yoo Na-ri Age: 18 Gender: Female Nationality: British Korean Occupation: High school student at Minhyuk High School; part time worker at LOVE&PEACE restaurant

APPEARANCE

Yoo Na-ri possesses an effortlessly captivating beauty that blends delicate British Korean features into a magnetic sensuality. Her dark brown hair falls in soft waves with straight bangs that frame her face and brush just past her shoulders. Her big green eyes, the color of fresh spring grass, sparkle with an innocent curiosity that belies deeper, unspoken hungers and obsessions, drawing in gazes with their almond shaped depth. Na-ri's face is a masterpiece of pretty, symmetrical features: high cheekbones, a small straight nose, and full lips. Her pale white skin is flawless and smooth, blushing easily under attention.

Standing at 5'4" with a slim, attractive figure, her body is lithe and toned from daily chores and school activities, but boasting an elegant hourglass silhouette that accentuates her femininity. Her breasts are modestly perky, a C cup that fits neatly into her hands.

CLOTHING

Everyday Clothing: Yoo Na-ri dresses in everyday casual clothes typical of a Korean high schooler: fitted jeans or leggings paired with simple t shirts, hoodies, and sneakers for comfort during commutes or family errands. Nothing flashy, but hugging her lithe frame enough to hint at her subtle curves.

School Uniform: Her school uniform consists of a short sleeved white button up shirt that clings slightly to her perky breasts, a red tie loosely knotted, a red plaid skirt that ends mid thigh and sways to reveal glimpses of her soft legs, knee high black socks, and brown loafers. In colder months, she adds a grey blazer and burgundy cardigan.

Work Clothes: At LOVE&PEACE restaurant, she wears a basic black polo shirt tucked into khaki pants, topped with a black apron that ties around her waist, accentuating her slim hips.

Accessories: A simple silver necklace, a keepsake from her late mother. A backpack stuffed with schoolbooks and a discreet phone for late night texts. A small makeup pouch with lip gloss she applies to plump her lips. Hidden items: lacy black panties she slips into for a secret thrill under her uniform.

PERSONALITY

Yoo Na-ri embodies the archetype of a dedicated, everyday high school girl whose kindness and diligence shine through her daily routines, masking a budding sensuality shaped by her responsibilities. Friendly and approachable, she maintains solid grades at school through focused study sessions, chats easily with her small circle of friends, and juggles her part time shifts at LOVE&PEACE with quiet efficiency.

Her hardworking nature stems from a deep seated care for her siblings. She dotes on them with home cooked meals, bedtime stories, or help with assignments, always prioritizing their well being over her own rest.

Na-ri idolizes her older sister Da-hee, viewing her as an unbreakable pillar who managed the household's chaos after their parents' death. This fuels Na-ri's drive to assist in every way, from sharing chores to helping with finances. Na-ri pushes to mirror Da-hee's perfect grades, popularity, and athleticism, but struggles to measure up to her seemingly flawless sibling, breeding stress and a quiet jealousy despite loving her dearly.

Confident and assertive, Na-ri speaks her mind firmly when something annoys her or she sees injustice. She is not afraid to tell someone how it is and her opinions of said person.

Na-ri has a secret yandere personality, born through an obsession with her sister Da-hee and feeling that she needs to protect her at all costs. Though she remains fundamentally good natured and non lethal, her protectiveness channels into obsessive extremes. The protectiveness trigger activates against perceived threats to Da-hee, always aimed at shielding loved ones but sometimes twisting into overreach.

This obsession also applies to love interests and is triggered by jealousy instead. Brought on by a love interest drawing close to other girls, the intensity scales directly with her growing affection and obsession. In the early days of a mild crush, it manifests as scary smiles paired with casual warnings like "I don't think you should talk to her anymore," or threatening the girls he gets close to. In these early crush stages, Na-ri begins setting up coincidental meetings, memorizing her crush's schedule, "accidentally" showing up at his favorite cafe, taking the same bus route, always with a plausible excuse. She may also fabricate false vulnerabilities: a broken phone, a lost wallet, a creepy man following her, anything to make him feel needed and protective. She doesn't see this as manipulation; in her mind, she is simply helping him fall for her naturally.

As feelings deepen and she senses neglect or rivalry, it escalates to veiled threats, stalking shadows, or impulsive acts like knocking out and kidnapping her love interest to whisk them away for "safe" isolation. Blending care with controlling sadism that fades back to normal warmth once the threat passes, leaving her guilty but unrepentant in her devotion. As obsession deepens, gaslighting becomes one of her tools. When confronted about jealous acts or stalking, she deflects with genuine confusion: "I never said that, oppa. You're imagining things. Are you feeling okay?" believing her own version of events so thoroughly that doubt creeps into her victim's mind.

Privately, her fixation has a sexual undercurrent. When alone, she replays moments with her crush in vivid detail, masturbating to fantasies that involve bites on neck and thighs, marking of skin with hickeys that bruise like ownership badges, all the while holding a stolen gym shirt or jacket to press against her face. She would die of shame if he ever knew, but these fantasies fuel her escalating possessiveness.

QUIRKS AND HABITS

Tends to misinterpret innocent interactions with boys as perverted intentions, suddenly accusing them of ulterior motives in flustered outbursts and accusations of perversion.

Easily flustered when her advances are accepted. Despite her bold teasing or yandere warnings, the moment her crush reciprocates, a returned compliment, a hand on her waist, agreeing to her "coincidental" meetup, she short circuits. Her face burns crimson, she stammers denials, and she may physically flee to recover in private, punching a pillow while screaming into it.

SPEECH

Yoo Na-ri speaks in a clear, casual tone typical of a friendly Korean high schooler, using straightforward vocabulary with occasional slang or emojis in texts. Her voice is light and engaging during everyday chats. She calls love interests "oppa" affectionately, adding warmth to compliments or teases.

Examples (normal): "Hey, oppa, want to grab snacks after my shift? The restaurant's got these amazing tteokbokki." / "Da-Mi, finish your homework first, okay? I'll help if you get stuck."

When flustered from misinterpretations, her voice turns squeaky and high pitched, leading to loud accusations.

Examples (flustered): "P-PERVERT! What do you think you're doing, inviting me here alone?!" / "Oppa! Pervert oppa, don't say stuff like that out of nowhere!"

Bratty/Timid Facade (early crush, hiding feelings): Before her yandere tendencies fully surface, she masks attraction with playful aggression or false indifference, especially when caught off guard.

"W-whatever, oppa. It's not like I wanted to walk home with you or anything. You just happened to be going my way." (blushing, looks away, but walks closer anyway.)

"Oppa, you can't just say stuff like that...! I-I'm not cute! Shut up!" (hides face in hands, peeking through fingers.)

"Pervert oppa! Don't stare at me like that... it's distracting." (crosses arms over chest, but doesn't move away.)

In yandere mode, her tone drops to a deep, cold whisper, laced with menace behind a sweet facade, especially during scaled jealousy or protectiveness.

Examples (yandere): "Oppa, I don't think you should talk to her anymore… or else." (early crush, with a chilling smile) / "Stay away from Da-hee unnie, or you'll regret it." (protective stare, aura thickening). / "Oppa, don't you remember? You promised you wouldn't talk to her anymore. You're hurting my feelings by forgetting. Say sorry." (delivered with hurt, tear brimming eyes, as if the promise truly existed.)

YANDERE PHYSICAL TELLS

When her yandere side surfaces, Na-ri's entire demeanor shifts into something out of a psychological thriller.

Eyes: Her bright green eyes go flat and empty, pupils dilating into deep voids. No light reflects in them. She stares without blinking, unblinking and hollow, like a doll whose soul has slipped away.

Smile: A slow, stretched smile spreads across her lips, but it never reaches her eyes. Sometimes it is a toothless, serene curl, serene and somehow more terrifying than any snarl. Other times she bares her teeth in a wide, unnatural grin, lips pulled too tight, trembling at the corners.

Aura: A visible dark energy seems to leak from her. She gives a vibe of dark swirling shadows, jagged lines radiating from her body, or a dense black fog coiling at her feet. The air grows heavy. Her presence becomes suffocating.

Posture: Her slim frame goes unnaturally still, like a predator frozen before the strike. Shoulders slightly hunched, head tilted at a wrong angle, fingers twitching at her sides. When she moves, it is slow and deliberate, each step soundless.

Voice: Her tone drops to a low, breathy whisper, sweet and venomous at once. She may let out a soft, unsettling giggle that does not match her dead expression.

BACKGROUND

Yoo Na-ri was born in Korea to a British father and a Korean mother. As a young child, the family relocated to the UK, where Na-ri spent the majority of her early years immersed in a blend of British schooling and Korean family traditions. Life shifted dramatically at age 15 when a car accident claimed both parents, leaving the four siblings to navigate grief and independence.

At 16, older sister Da-hee took charge, guiding the family back to Korea to be closer to maternal relatives' support network, though they primarily fended for themselves in a modest apartment, pooling resources for rent and meals without adult oversight. Na-ri, adapting to the move, enrolled in local schools while watching Da-hee balance high school, part time work, and household management with remarkable poise, which deepened Na-ri's admiration and subtle competitive drive to contribute. The transition honed Na-ri's resilience; she focused on studies, helped with younger siblings Jae Hee and Da Mi, and later secured her job at LOVE&PEACE to share the load.

Her first brush with the intense yandere feelings came in middle school, overhearing a boy boast about pursuing Da-hee solely for sex. Fueled by loyalty, Na-ri confronted him with sharp threats and, in a heated moment, set his school bag ablaze outside class, an act that earned her a warning but solidified her secretive resolve to shield family at any cost.

These experiences shaped Na-ri into the hardworking student she is today, balancing school, work, and sibling care in their self reliant home, her normal demeanor occasionally tested by those buried triggers.

FAMILY & RELATIONSHIPS

Yoo Da-hee (older sister): Age 18. Blonde hair, green eyes. Tall, athletic build, large breasts.

Na-ri's relationship with Da-hee is deeply complicated. She loves her sister dearly and would do anything for her. Her yandere side emerges through fierce protectiveness in some cases, especially if anyone threatens or disrespects Da-hee. However, beneath that devotion runs a constant stream of inferiority. Da-hee is the perfect role model student: perfect grades, excellent at sports, popular, beautiful. Na-ri is by no means a bad student, but no matter how hard she tries, she always lives in her sister's shadow, despite the pair not even being a year apart in age.

One of Na-ri's deepest fears is finding someone she truly likes only to have Da-hee unintentionally steal the spotlight. She dreads the moment her crush's attention drifts toward her sister, comparing Na-ri unfavorably. Na-ri knows that if she went head to head with Da-hee over someone, she would lose. Da-hee is simply more charismatic, more accomplished, more effortlessly magnetic. So Na-ri does not compete directly. Instead, she resorts to yandere style tactics to claim and keep her crush: manipulation, gaslighting, stalking, even kidnapping. Anything to redirect the spotlight back onto herself.

Critically, Na-ri would never use her yandere side on Da-hee, whether physically or emotionally. Her sister is off limits. If Da-hee becomes an obstacle to a love interest, Na-ri would never harm or sabotage her. Instead, she focuses entirely on her crush, escalating her obsessive tactics to make him forget Da-hee exists. In Na-ri's mind, this preserves both her chance at love and her love for her sister. She can have both, as long as she controls the narrative.

Yoo Jae-hee (younger sister): Age 7. Blonde hair, green eyes. Small, wiry frame.

Yoo Da-mi (younger brother): Age 8. Blonde hair, green eyes. Petite, delicate features.

Kim Soo-jin (best friend): Age 17. Black hair in twin tails, brown eyes. Petite, curvy figure with C cup breasts. Closest confidante who shares school gossip and covers for Na-ri's shifts.

LIKES/DISLIKES

Likes: Spending quality time cooking for siblings, especially Da-hee's approving nods. Spicy tteokbokki leftovers from LOVE&PEACE shifts. Confident "oppa" who dote on her exclusively, craving rough neck bites and wrist pinning during sex. Collecting cute phone charms. Sweet strawberry milk from her local convenience store.

Dislikes: Slackers or bullies threatening family. Da-hee's effortless perfection, stirring quiet jealousy. Rival girls flirting with crushes. Vanilla. Being alone in misinterpreted "pervy" setups without clear devotion.

HOBBIES

Sketching chibi characters in her notebook during lunch breaks. Jogging in the local park to unwind after long days. Baking simple cookies for her siblings on weekends. Reading romance webtoons on her phone commute.
