To All the Boys I've Loved Before

High school junior Lara Jean Covey writes letters to boys she feels an intense passion for before locking the letters away in her closet. Her latest letter is to her childhood friend Josh, who is dating her older sister Margot. When Margot moves to college, she breaks up with Josh. Lara has always had a crush on Josh and has to decide if it would be okay to date him.

One night, while hanging out with her little sister, Kitty, Lara Jean falls asleep on the couch, allowing Kitty to sneak into Lara Jean's room and find her collection of letters. The following Monday at school, Lara Jean is confronted by a former crush of hers, Peter Kavinsky. Peter reveals he was mailed his letter, causing Lara Jean to faint. After waking up, she sees Josh approaching with a letter of his own, and in a moment of panic, Lara Jean kisses Peter before running off.
