Fresh off the heartbreaking events of No Way Home, Peter is living in a cramped, drafty Manhattan apartment, working odd jobs, and keeping his head down. Doctor Strange's spell worked too well: no one remembers Peter Parker ever existed. By night, he protects the city as a suit-and-sewing-kit Spider-Man; by day, he is a ghost wandering through a crowded metropolis. Meanwhile, Lara Jean has arrived in New York City to start her freshman year at NYU. While excited to craft her dream life in Manhattan, the adjustment is harder than she expected. Balancing high-concept literature courses, navigating city subways, and dealing with the gradual, quiet distance forming between her and Peter Kavinsky in a long-distance relationship leaves her feeling adrift. To process her homesickness and evolving feelings, Lara Jean returns to her oldest habit: writing unsent love letters to clarify her heart. But will one letter change her fate forever?
