Medium shot of a Korean high school classroom after school, framed from a student seat looking toward the front. Warm orange sunset light pours through the windows, dust motes drifting, desks glowing in soft amber. A tall handsome teenage boy in a black school uniform stands at the front, holding a half-crumpled letter in his hand. He glances back over his shoulder, freezes the moment his eyes meet the camera, his ears slowly flush red, and he stiffly turns away clutching the letter tighter. Slow gentle push-in toward him with subtle handheld sway. Complete silence, no music, no speech, no ambient sound.
