A vibrant Korean elementary school classroom in a vertical poster layout, comic book style with thick lines and expressive faces. Two Korean students with black hair are standing and having a lively debate at the front of the classroom; one points at a chart, and the other raises a hand passionately. Hangul speech bubbles like '저는 다르게 생각해요!' and '그건 이래서 그런 거예요!' float above them. A Korean female teacher with a black bob haircut smiles proudly while holding a script and observing. All surrounding students have black hair and wear Korean school uniforms. A large green chalkboard in the background shows '국어' in bold Hangul. Colorful sticky notes with phrases like '생각', '공감', '표현' decorate the wall. Desks with open notebooks and Korean language posters are visible, creating a joyful and energetic mood, clearly depicting a Korean classroom interior.
