Lara Jean and Peter have just taken their romance from pretend to officially real when another recipient of one of her love letters enters the picture.
Senior year of high school takes center stage as Lara Jean returns from a family trip to Korea and considers her college plans — with and without Peter.
Hopeless romantic Stensland thinks he's found true love with an older woman, Morgan, only to learn that she's married and that their fling is merely an instrument of revenge against her neglectful husband, Grady. Initially out for blood, Grady finds himself strangely sympathetic to Stensland's plight and decides to get revenge on his wife instead.
