Cinematic 30-second Korean high school classroom action-comedy, photorealistic, warm golden sunlight streaming through large windows, shallow depth of field, 24fps, 16:9. Characters: - Teacher: young Korean woman in a dark teal hanbok with gold floral embroidery and a deep maroon skirt, hair in a low bun, small round dark sunglasses, cool and deadpan attitude. - Sleeping student: tall delinquent with bleached blonde hair, black school blazer, loose tie, looks tough. - Classmates in gray school uniforms. Scene 1 (0-3s): Wide shot from the back of a sunlit classroom. Students sit at wooden desks, some dozing. The teacher stands at the green chalkboard far ahead, drawing a chalk diagram. Scene 2 (3-6s): Medium close-up of the teacher at the chalkboard. The diagram shows a stick figure standing on a block, a dashed arc trajectory, and a stick figure crouching to push a rolling log. She turns her head with a deadpan look over her sunglasses and says in Korean "누가 수업시간에 자니?". Subtitles in 3 lines: Korean / "Who's sleeping in my class?" / Japanese "授業中に寝てるのは誰?" Scene 3 (6-9s): Slow-motion shot of a white chalk stick spinning through the air across the classroom, blurred teacher in the background. Scene 4 (9-12s): The chalk flies between desks past classmates' faces, lands precisely on the forehead of the sleeping blonde student. Scene 5 (12-15s): Extreme close-up of the blonde student lifting his head from his arm, chalk stuck on his forehead, angry glare. Then a classmate in the back row calmly records everything on his phone. The chalk breaks into dust on the empty desk. Scene 6 (15-21s): Back at the chalkboard, the student storms up and throws a punch. The teacher dodges in her hanbok and says "미안하게 됐네." Subtitles: Korean / "My bad." / "すまねえな。" Fast martial-arts choreography, her hanbok sleeves flowing, his tie flying. Scene 7 (21-26s): Her counter-strike lands with a shockwave, the student is blasted backward, cracks spread across the chalkboard wall, debris and dust fly. Scene 8 (26-30s): The wall is blown through with a huge hole, dust settling, classmates stunned in the background. Final close-up of the teacher's face with sunglasses, calm and unbothered, the broken hole beside her. Style: realistic cinematic lighting, dust particles in sunbeams, dynamic camera moves, slow motion on the impacts, comedic tone, crisp sound design (chalk whoosh, impact thud, wall crumbling), no music vocals.
