Lara Jean gets a letter from John Ambrose McLaren, an old classmate who has moved away. He writes that he has only just received a letter that she wrote him last summer (which he was not intended to get at all). He tells her how touched he was by the letter, and she recalls how much she used to like him.

Peter picks Lara Jean up to drive her to school. She discovers that he is texting when she gets in his car and asks him who it is; he tells her that he is writing to Genevieve. Lara Jean tells him about the letter from John, and Peter doesn’t seem jealous, which annoys her. He asks her if John mentioned him in the letter, since they used to be close friends.

This chapter is a letter that Lara Jean writes to John. In the letter, she tells him how she never intended for him to get her love letter and how she used to write private letters for many boys she liked: letters which Kitty then distributed.

Lara Jean reminisces in her letter about a pizza party that they had back in middle school and about how pushy Peter was about eating the last slice of pizza.
