manga interior, commuter train carriage, late afternoon light through windows casting clean shadow bands, two seated characters not facing each other, tension shown through eye direction and body language, one character’s hand holding a strap with slight squeeze, the other holding a book with a bent corner, minimal crowd silhouettes for rhythm, precise perspective lines of seats and poles, clean negative space around faces, crisp ink lineart, selective hatching for depth under seats, subtle tone gradient outside windows, cinematic framing, panel-ready clarity
