Kai Gibson, 15, and Kimberly Moncada, 14, were on the way from their homes in Bushwick to Saturday exam-prep sessions in Flatbush. Moncada had been up since 5:30 in the morning. “I got up at 7:20,” said Gibson. “I was still in bed when she texted me telling me she was ready.” This isn’t the first serious relationship for either of them, but with Gibson, Moncada said, there is “more of a connection than in my past relationships.”

Nubia Royal, 28, and her husband Jay Lighter, 29, were visiting from Miami for a “sip and shop” design event. “I’m half-Haitian,” she said, “and in that culture they don’t think that fashion is a real career, art is a real career.” She was wearing clothes of her own design; Lighter, she said, had been a supportive companion, including carrying bags filled with her dresses. They’ve been married for two years.

Omar E. Montague, Jr., 24, and Kimara Guichon, 24, were outside a bar in the early morning. “I recently got out of a three-year relationship,” said Montague, “so I’m kind of like, I guess, a little clumsy on the bike.” Guichon could tell he liked her when she saw he’d saved her phone number with emojis next to her name. “I feel like when I save people with emojis,” she said, “it’s because they pique my interest.”
