The summer heat in Seoul had turned brutal by mid-July, but Minjun’s sprawling mansion felt like a private tropical island. Floor-to-ceiling glass walls, infinity pool that seemed to spill straight into the river view, outdoor bar stocked with top-shelf everything, and cabanas draped in white linen that fluttered in the breeze. Minjun had decided to throw an “intimate” pool party for a handful of business associates—ten couples, champagne on ice, catered sushi, and a DJ spinning low-key house beats. The kind of event where deals were sealed between cocktails and everyone pretended the wives weren’t half-naked.
