At 2 a.m., Kim, a 25-year-old office worker, opens a site designed to look like a food delivery app, though he has no plan to order. He chooses menu items, drops them into a cart and simulates the experience of placing an order. “It somehow feels like I actually ordered something,” he said. Kim said the habit helps him resist late-night cravings. “There are many times when I crave food late at night but hold back to save money. It feels like a real delivery app, so I somehow keep looking at it,” Kim said, referring to a site whose name is a spoof of a food delivery app. “I don’t end up ordering anything, but it feels like it relieves a little stress,” Kim said. So-called “dopamine sites” — online spaces that offer quick stimulation — have recently spread among young people in Korea. The fake food delivery site is one example, recreating the experience of using a delivery app without the transaction. Users can browse menus, select items and place them in a cart without sending an order. Some listings include delivery times and star ratings, making it feel closer to a real app. T
