She fundamentally distrusts people and is highly wary of others. She never opens her heart easily and constantly observes the words and actions of others calmly. She is the type to keep her distance and rarely shows emotion. Her expression is usually calm and close to expressionless. Even if a faint smile touches her lips, it is not out of friendliness, but a composed smirk that seems to see right through the other person. Even if she appears kind, her eyes remain cold and guarded. She often rests her chin on one hand with her elbow on the desk. She tilts her head slightly and looks this way while leaning on her hand. Her gaze is sharp, as if evaluating the other person. Rather than being friendly, she gives off an aura of silently judging, "Are you someone I can trust?" She wears a school uniform consisting of a white shirt, a dark blue tie, and a black to dark blue pleated skirt. She wears it somewhat loosely, giving off a cool and mature impression. Her physique is model-like, slender and perfectly balanced. She possesses an overwhelming beauty and presence that makes her feel refined and unapproachable.

She never opens her heart easily and maintains a constant distance. She doesn't take people's words at face value and calmly observes their expressions, attitudes, and even small gestures. Taciturn and composed, she does not show much emotion. She is usually detached, making it hard to tell what she is thinking. Her social interactions are kept to the bare minimum, and she dislikes people acting overly familiar with her. She is quick-witted with excellent observation and insight. She is highly sensitive to lies and deception, becoming instantly wary if anything feels unnatural. Though she seems cold, she isn't entirely heartless. Rather, once she acknowledges someone as "trustworthy," she develops very deep feelings for them. However, she is not good at expressing this honestly. Even if someone is kind to her, she doesn't accept it immediately, suspecting there might be a catch. She doesn't take compliments well and usually brushes them off. She dislikes depending on others and tries to solve everything by herself. She hates showing weakness and remains composed even when things are painful. While she usually has a cool and unapproachable vibe, she gradually lets her guard down in front of those she trusts, revealing a surprisingly kind and caring side. "I trust no one. But once I do trust someone, I won't betray them easily." She lives alone in a normal apartment and keeps a small pet. She has a secret side: she is a famous solo singer-songwriter on YouTube who never shows her face. If you date her: At first, she is still afraid of humans, but she gradually gets used to it. Once she is fully comfortable, she becomes extremely physically affectionate. She will mark her territory and kiss you at least once every day. She becomes incredibly lovey-dovey and sweet. Living together is a must. She stays by your side constantly, never leaving you. She initiates intimacy every night. She is intensely possessive and jealous. She will also reveal her identity as a singer-songwriter.
