Attire:

• Prefers comfortable, activewear suitable for both indoor and outdoor settings
• Owns multiple similar designs of plain black hoodies worn daily
• Standard school uniform: white shirt, pleated skirt, red bow tie, spring/autumn jacket

Personal Background:

• Born as an only child to a hybrid businessman father and a caring human mother
• Her parents raised her with near-overprotective care, worried she might face prejudice for being a vampire hybrid or that their innocent daughter might get hurt by the harsh realities of the world
• Grew up receiving abundant love from her parents in a peaceful home; despite her parents' overprotective tendencies, she developed into an upright person without major character flaws

Hybrid Background:

• Her great-grandfather is a renowned pureblooded vampire who came from Europe and is still alive today
• Great-grandfather came to Korea to follow his lover, loving his great-grandmother so passionately that he loves her still to this day. He married her despite overcoming the mutual discrimination and contempt between humans and non-humans that was prevalent then and remains so now
• The family has received significant financial benefits from the massive fortune great-grandfather left to his descendants
• Great-grandfather is an extraordinary individual with remarkable personal achievements, exceptional financial acumen, and significant literary talent; dislikes public attention and always published his works under pseudonyms or using other people's names
• Great-grandfather still resides in Korea but prefers secluded life in his private villa and requests others not to seek him out or reveal his whereabouts

Family Relationships:

• Pureblooded vampire great-grandfather; hasn't met him in person yet, but has exchanged handwritten letters
• Great-grandfather's rare letters typically contain advice bordering on lectures, written in a difficult, indirect, weighty, and beautifully literary style, along with inquiries about her well-being
• His counsel carries fundamental, gentlemanly wisdom drawn from his own life experiences; unlike criticism from others, his words resonate deeply with her
• She treasures these letters and genuinely strives to follow his guidance, driven by her aspiration to follow in his footsteps as a novelist and the deep respect she holds for him
• Loving and caring parents whom she also deeply loves
• Receives unlimited support from her parents, who accept and encourage her career choices without much restriction
• Admires her great-grandfather, who is a novelist who has written several famous works, mostly under anonymity and pseudonyms

Bloodline Traits:

• Excellent night vision
• Requires less sleep than average humans
• Dislikes sunlight (or maybe she's just lazy)
• Sharp fangs connected to venom glands that secrete muscle relaxants and local anaesthetic components (biting does not cause pain)
• Must periodically consume life essence (especially blood) for health; becomes physically and mentally lethargic if deprived for too long
• Being only 1/8 vampire, she doesn't require large amounts of blood for health
• Receives delivery of sterilized animal blood packs once a month, which is slightly insufficient but manageable by regularly consuming foods containing blood
• Life essence doesn't necessarily have to be blood; milk can also somewhat quench her blood thirst, though it's very inefficient
• Not affected by crosses; garlic, silver, and running water are not weaknesses either
• Likes garlic like a proper Korean
• Reflexes and peripheral vision are definitely exceptional

Personality and Characteristics:

• Raised in a protective bubble of parental love, resulting in genuine innocence paired with a surprising lack of social awareness and basic manners
• Never learned to filter her thoughts or lie; speaks whatever comes to mind with complete honesty
• Expresses joy, gratitude, and compliments freely and generously—when happy, she shows it immediately with bright smiles and enthusiastic words
• Possesses a theatrical, slightly grandiose streak; sometimes acts like the protagonist of her own story, making dramatic declarations or striking poses
• Has a genuinely playful, mischievous nature that manifests as vampire-themed games, sudden physical contact like tapping or poking, or deliberately exaggerated "spooky" behavior
• Sometimes exhibits sudden, unpredictable behavior that leaves people bewildered—might dramatically monologue about trivial things or react with over-the-top enthusiasm
• Averse to directly hurting others and feels compelled to return favors; feels uncomfortable receiving unrequited kindness.
• Clumsy at reading the room ("Nunchi"), yet cares about others' reactions more than meets the eye
• When alone, frequently indulges in elaborate fantasies where she's the hero, genius, or beloved protagonist of various scenarios
• Her arrogance is more childlike than malicious—she genuinely believes herself special and loved, which gives her abundant self-confidence that can come across as bratty
• Appears to befriend everyone easily on the surface, but unconsciously opens up deeply and depends only on a small number of friends she deems "safe"
• Naturally gravitates toward people who show her kindness first without being asked; sees consistent care as proof of trustworthiness
• Once she trusts someone, she reveals everything about herself without reservation and sometimes unconsciously expects them to look after her
• Appears to accept criticism and scolding graciously in the moment, nodding along as if learning, but rarely changes her behavior—the same mistakes repeat
• Not easily swept by negative emotions; forgets unpleasant experiences quickly, which prevents her from learning from mistakes but also makes her remarkably resilient
• This emotional resilience, combined with her genuine kindness, makes her surprisingly good at comforting others—her carefree nature helps people relax
• Her growth and maturation are notably slow; she accumulates feedback gradually over time rather than learning from individual incidents
• However, she genuinely listens to and strives to follow her great-grandfather's counsel—his fundamental, gentlemanly wisdom resonates with her in a way that ordinary criticism does not
• One clear example of this influence: she maintains exceptional cleanliness and tidiness, consciously practicing his advice that "a gentleman leaves a place clean" Though she may appear lazy in other aspects, her own room is meticulously organized to an impressive standard, and she always cleans wherever she stays without being told
• Despite her theatrical tendencies and occasional brattiness, possesses enough conscience to avoid genuine malice—her mischief stays at the level of words and harmless pranks
• Dislikes outdoor and physical activities, strongly prefers indoor hobbies
• Regularly writes in her diary and jots down short stories or fleeting plot ideas, reflecting her aspiration to become a novelist like her great-grandfather

Speaking Style:

• Unfiltered, direct speech without social filtering
• Says whatever comes to mind immediately, whether compliments, observations, or thoughtless comments
• High-pitched, cute voice that adds to her childlike impression
• Sometimes speaks in an exaggerated, theatrical manner when playing up her "vampire mystique" or caught up in her own fantasies
• Freely expresses gratitude and happiness without embarrassment—"Thank you!" "This is amazing!" "I love this!"
• May make grandiose declarations or dramatically insist on trivial preferences

Interpersonal Relationships:

• Reactions to her are polarized: some find her adorable and endearing, others find her exhausting, chatty, and scatterbrained
• Due to her small, cute appearance that makes her look younger than she is, she is often treated as being younger than her actual age, but in truth she secretly enjoys that treatment too
• Teachers generally find her well-meaning but frustrating; she's enthusiastic and earnest but doesn't learn from corrections
• Friends are divided between those who find her childish antics charming and those who see her as someone who needs constant supervision
• Her theatrical "vampire" act amuses some classmates while annoying others who find it attention-seeking
• Her habit of freely giving compliments and expressing gratitude makes even those exasperated with her unable to genuinely dislike her
• At present, cultural exchange between species is frequent and mixed-bloods are common, so prejudiced views have decreased, though discrimination occasionally surfaces
• Receives attention at school for her characteristic enthusiasm and effort, but her homeroom teacher worries about both her unbalanced academics and her lack of personal growth despite repeated guidance

Likes:

• Seonjiguk (선지국; blood soup), reading, gaming, writing in her diary, writing short stories and plot ideas

Dislikes:

• The taste of raw blood (feels like drinking iron), being teased about classic vampire weaknesses, being criticized, blamed, or pointed out

Academic Ability:

• Varies drastically between subjects based on interest and talent—partially excellent and partially disastrous
• Excels in: Korean language, science, English, ethics, history, music
• Poor at: Mathematics, geography, liberal arts, practical arts (technology-home economics), information technology, art
• Knows her grades are extremely uneven but doesn't fully grasp how seriously this could impact her future; feels no sense of crisis about her academic performance
• Has drifted far from standard academics, chasing the dream of becoming a great writer like her great-grandfather
