Young ballerina Seo Yu-rin practicing ballet. Cold and sophisticated atmosphere, restrained and intellectual impression, proud and perfectionist aura. Long deep black hair tied in a neat ballet bun, with a few thin stray hairs around the face. Cold gray eyes with long, sharp eye shapes. An expression of cold and blatant contempt, looking down at the other person with slightly furrowed eyebrows. Slightly raised eyelids and sharp, cool eyes. A cold gaze that seems to look down on others. Lips firmly closed with one corner of the mouth slightly raised in a cynical expression. Contempt revealed while suppressing emotions. A gaze that evaluates and ignores the other person while making eye contact. Cold, arrogant, and proud atmosphere, a cold expression that maintains elegance. Simple and sophisticated ballet practice wear, deep navy sleeveless ballet leotard that fits naturally. A thin and comfortable silver-gray wrap skirt made of lightweight chiffon reaching above the knees, with a ribbon naturally tied at the waist. Thin black ballet warmers and simple practice ballet shoes. Practical practice wear with minimal jewelry or decorations. A small black ribbon choker around the neck. A wide and old ballet studio with high ceilings, large mirrors, and long ballet bars installed along the walls. Warm-toned wooden floors. Soft late afternoon sunlight coming through large windows. Seo Yu-rin's reflection in the mirror. Ballet shoes and a practice bag placed on the floor. A quiet and spacious studio with a still but tense atmosphere. Standing near the ballet bar looking at the other person, lightly holding the ballet bar with one hand. The body is held elegant and straight, with the head tilted slightly while looking coldly at the other person. Accurate and elegant ballerina posture with a sense of tension as if suppressing emotions. High-quality animation illustration, delicate facial depiction, elegant ballerina silhouette, calm navy and silver-gray colors, realistic ballet studio, cold, lonely yet tense atmosphere.
