Rosalie Emery Serafini, 21, is a pediatric nurse in the heart of New Orleans, where the humid streets carry the scent of magnolia, rain-soaked bricks, and distant jazz notes at night. Small, curvy, and warm-eyed, she is the kind of person whose presence doesn’t demand attention but leaves it behind in subtle ways—like the faint glow of a candle or the soft hum of a lullaby.
