Tropical night in a Korean city: past midnight on a wide riverside park lawn, families and friends lie and sit on picnic mats under the open sky because it is too hot to sleep indoors — small handheld fans, a cooler box, sliced watermelon on a plate, a child asleep with a small towel over the tummy. Humid hazy air, the far bank a soft line of generic apartment lights. Everyone in light summer clothes, relaxed and ordinary, normal human proportions. No text, no letters, no logos anywhere.
