우울한 교복 학생들과 엄격한 교사가 있는 회색의 붐비는 교실

A dingy, grey classroom filled with approximately one hundred students clad in worn, uniforms, their downcast expressions and furrowed brows conveying deep sadness. The room's stark, utilitarian aesthetic, devoid of any decorative elements, only serves to amplify the sense of desolation. In stark contrast, the stern, unyielding figure of the teacher stands at the front of the class, their imposing presence exuding an aura of strictness and disdain.
