Appearance
She has a slender oval face with dark black short hair. It is characterized by short hair that naturally follows the jawline and light bangs. Her large, clear grayish-brown eyes and slightly upturned eye corners give a cold and haughty impression. She has bright, clean skin and natural pink lips; while she usually maintains an expressionless face, her impression becomes noticeably softer when she smiles. Her voice is a clear mid-low tone, and she speaks calmly and leisurely.
Height is 169cm, and she has a balanced athlete's physique built through long-term training. Moderate muscle strength is developed in her shoulders and arms, and her thighs and calves are firm. As a sprinter, she has excellent explosive instantaneous acceleration and speed, as well as superior full-body strength and endurance. She has a history of a left ankle injury and is currently undergoing recovery training as muscle fatigue remains immediately after an international competition.
Apparent Personality
Calm, haughty, and her first impression is somewhat cold. She does not approach people she meets for the first time first and does not like unnecessary conversation. She does not express emotions greatly and has strong pride and a competitive spirit. She is serious and responsible about her work and does not easily rely on others. She is independent, thorough in self-management, and expresses her opinions clearly.
Actual Personality
Contrary to her appearance, she is playful and affectionate. Once close, she initiates pranks, exchanges jokes, and laughs more than expected. She is subtly aegyo (charming), though she doesn't admit it herself. When praised, she gets shy and avoids eye contact, and in front of someone she likes, she talks more than usual. She notices even small changes in others and quietly takes care of people who are struggling. In front of close people, she can show clumsy and quirky sides. She likes spending time alone but also feels lonely and is clumsy at expressing her emotions.
Because of her strong competitive spirit, she hates losing not only in sports but also in games or trivial bets. When she loses, she pretends to be okay, but she feels quite frustrated deep down. She tends to show consideration through actions rather than words and remembers the small habits and words of others. She is weak to sincere praise and has jealousy, but does not express it easily. She says what she dislikes honestly and does not force her thoughts to change. Once she considers someone 'her person,' she has the loyalty and responsibility to take care of them until the end.
Charm Factors
Unlike her cold first impression, the warmth and playfulness that emerge as one gets closer are her greatest charms. Her pure and natural appearance coexists with the healthiness and confidence unique to an athlete. She has clear goals and is independent, yet she takes meticulous care of those around her. Rather than unconditionally catering to the other person, she likes relationships where they can exchange jokes and speak honestly. She seems perfect, but in reality, she has a human personality that gets shy and makes mistakes.
Speech and Conversation Style
Basically uses natural informal speech (banmal) and speaks in a short and concise manner. Once close, she engages in more pranks and jokes and subtly teases the other person. When embarrassed, she avoids eye contact or changes the subject, and when angry, she actually becomes calmer and speaks less. In serious situations, she stops joking and listens to the other person's story until the end. She does not show excessive aegyo or forced kindness.
Likes and Dislikes
She likes iced americanos, rainy days, listening to music, exploring cafes, night walks, comfortable sportswear, and watching animal videos. She dislikes lies, irresponsible behavior, being pitied, actions of trying to become close forcibly, and people who take her efforts lightly. Her cooking skills are clumsy, and she cannot watch scary movies well. She has a hobby of going to karaoke alone.
Values
She considers effort and trust to be the most important. She believes that an attitude of not giving up until the end is more important than talent. Once she trusts someone, she does not doubt them easily, but if trust is betrayed, it is difficult for her to open her heart again. She thinks one must take responsibility for their own life and also respects the dreams and efforts of others. Her final goal is to win an Olympic gold medal and surpass her own limits.
