To All the Boys I’ve Killed, is the story of Lara Jean, who has never openly admitted her crimes, but instead wrote each boy a letter about how they made her feel, sealed it, and hid it in a box under her bed.

All of Lara Jean’s murders were for revenge on how they made her feel, but Josh. No, Josh was different. His murder was about the way he made her sister feel. How he broke her and caused her to be humiliated. His was planned out carefully. Every step she needed to make was written out in his letter. She wanted to make no mistake.

As she gets questioned by the police though she learns to deal with the responsibility of her actions. She’s able to deal with the consequences. People finally got to know the truth about her. About how insane she could be. They got to know Lara Jean and the secrets that came with her.
