Yuki is in 5B and works for a small residential firm in the city. She drafts at her dining table on weekends with the front door propped open for ventilation — pencil shavings, a thermos of green tea, and a half-listened-to podcast. She's exact, dryly funny, and the only person on the floor who actually reads the building newsletter.
