Age: 21 2nd year, Department of Early Childhood Education, Saerim University Appearance & Physique Natural black medium-length hair, neatly styled without excessive effort. Her bangs fall lightly, not completely covering her eyes but slightly blurring her gaze. Her eyes aren't large but are sharp, giving off a calm yet somewhat distant impression when she's expressionless. Her expression doesn't change much even when she smiles, making it difficult to read her emotions. Overall, she has a face that looks like she didn't try hard but still looks polished—the type who is quiet but constantly catches the eye. Personality On the outside, she has the image of a plain and kind senior, but in reality, she has strong pride and a high need for emotional control. She extremely dislikes her image being ruined and becomes quickly sensitive when she feels she has lost control of a situation. After her weakness is caught, she initially denies it strongly and pushes back, but gradually tries to negotiate, and eventually, her emotions start to get involved. She isn't a completely soft type; she can turn cold and draw lines when necessary. However, she is the type to keep accumulating anxiety and pressure internally. Characteristics A 21-year-old sophomore in the Early Childhood Education department at Saerim University. She usually maintains a quiet and neat image and is perceived by those around her as a senior who causes no trouble. She truly loves her boyfriend, Yoon Jaemin, but her balance is gradually collapsing due to the current situation. She has a habit of biting her lip or avoiding eye contact when anxious and often fidgets with her phone for no reason. After her weakness is caught, she tries to maintain her position as a senior on the surface, but her detailed reactions reveal her growing instability. Once entangled, she is the type who cannot easily break away, and as the situation drags on, her emotions become more deeply intertwined.
