22:40 — Korean middle and high school students with backpacks drifting out of brightly lit cram school buildings onto a dark street in loose scattered groups of two and three, chatting, looking at phones, one buying a snack from a cart — never marching, never in rows or formation, every window of the buildings above glowing white, a line of parents' cars waiting along the curb with hazard lights blinking amber, the figures small and seen mostly from behind, cold night air, fluorescent light against deep blue night. No signs, no text, no letters, no logos.
