Aswin Sekhar lived in a narrow apartment above a bookshop that smelled of dust and lemon oil. He learned small, perfect rituals early: waking to the light through the blinds at 6:07, brewing exactly one cup of black tea, and sorting the day’s errands into three neat columns on a torn postcard. Routine made the world predictable, which was what he wanted after his father left and the city taught him how little sense people made.
