To All the Boys I've Loved Before

Shy high school junior Lara Jean Covey writes letters to boys she has strong feelings for before locking them away in her closet. One of the letters regards her childhood friend Josh Sanderson, who dated Lara Jean's older sister Margot until she broke up with him before leaving for college. Lara Jean finds her feelings for Josh resurfacing, but chooses not to pursue him, opting to instead write a postscript to Josh's letter before putting it back in her closet. One night, Lara Jean falls asleep on the couch while hanging out with her little sister, Kitty, who sneaks into her room and finds her collection of letters. The following Monday at school, Lara Jean is confronted by a former middle school crush, Peter Kavinsky. He explains that he received her letter, causing her to faint. After waking up, she sees Josh approaching with his letter, and in a moment of panic, Lara Jean kisses Peter to throw Josh off before running away. Lara Jean encounters Lucas, another of the letter recipients, who she learns is gay. She begins to realize that all the letters have been mailed. Lara Jean later leaves her house to avoid both Josh and Peter, but Peter follows her to a diner. She explains her situation and tells him that their kiss was to dissuade Josh. Peter proposes that he and Lara Jean fake a relationship in order to make his ex-girlfriend Gen jealous, as well as convince Josh that Lara Jean no longer has feelings for him. She agrees after they negotiate the dos and don'ts, and as the next few months go by, the whole school, along with their respective friends and families, believe they are dating. As Peter and Lara Jean spend more time together, they find themselves conflicted by their developing attraction to each other. Gen expresses her jealousy to Peter, who hesitates to end the relationship with Lara Jean. On the school ski trip, Peter admits his feelings for Lara Jean, and the two end up kissing while alone in a hot tub. At the end of the trip, Gen tells Lara Jean that Peter spent the night in her room after the kiss, then taunts Lara Jean with her favorite scrunchie, which she took from Peter. Furious, Lara Jean breaks up with Peter and storms home, where she finds Margot has returned from college. Peter arrives, attempting to explain that nothing happened between him and Gen, but Josh arrives as well to confront Peter. Margot overhears everything, and is upset when she learns of Lara Jean's former feelings for Josh. Things are worsened when, after Lara Jean asks Peter and Josh to leave, she sees that a provocative video of her and Peter in the hot tub has been posted on Instagram. Lara Jean reconciles with Margot, who comforts her. Kitty reveals she was the one who sent the letters. An enraged Lara Jean is calmed down by Margot, who reasons that Lara Jean may have wanted to send the letters but was too afraid to. The sisters forgive each other before getting Instagram to take down the video. After Christmas break, Lara Jean discovers that her schoolmates have discovered the video, and theorizes that Gen posted it. When she confronts her, Gen admits she tried to sabotage their relationship as she felt betrayed that Lara Jean kissed Peter during a spin the bottle game four years ago. After talking with her dad and her best friend Chris, Lara Jean reevaluates her relationships and reconciles her friendship with Josh. When she hesitates to tell Peter about her real feelings, Kitty shows her notes that he wrote during their 'relationship'. Lara Jean goes to see him, and he tells her that he is in love with her. They kiss before walking off together. In a mid-credits scene, John Ambrose McClaren, one of the five recipients of Lara Jean's letters, arrives at her door with flowers in hand.
