Cinematic 30-second live-action Korean high school comedy-action clip, 16:9, warm sunlit classroom, shallow depth of field, realistic photography look, subtle slow-motion on impacts. Characters: - A young female teacher in a dark green traditional hanbok with gold embroidery and a burgundy skirt, hair tied back, round black sunglasses, cool and unbothered expression. - A delinquent male student with bleached blonde hair, black school blazer, loosened navy tie, sleeping at his desk. - Classmates in grey school uniforms, one holding a phone and reacting in shock. Shot sequence: 1. Wide shot from behind the students: the hanbok teacher at the chalkboard drawing a chalk diagram of a stick figure jumping from a platform, and another stick figure pushing a log. Sunlight streaming through large windows. 2. Teacher turns, looks over her sunglasses and says "누가 수업시간에 자니?" (Who's sleeping in my class?) 3. She flicks a piece of chalk. Slow-motion shot of the chalk spinning through the air across the room. 4. Extreme close-up: the chalk hits the sleeping blonde student right between the eyes, then shatters into white dust on the desk. Classmates gasp. 5. The student jumps up angrily and charges at her. Teacher and student clash in a mid-shot in front of the chalkboard, her forearm blocking his punch, cracks spreading across the board behind them. 6. Student, now bruised and embarrassed, says "미안하게 됐네." (My bad.) 7. Final shot: close-up of the teacher's calm face with sunglasses, a huge crumbled hole in the classroom wall smoking behind her, dust floating, students stunned in the background. Style: Korean webtoon-meets-live-action comedy, warm natural light, crisp cinematic color grading, dynamic camera, bold white subtitles at the bottom in Korean, English and Japanese. Audio: school-bell ambience, chalk tapping, punchy impact sound effects, short comedic music sting.
