To all the boys Ive loved before

Lara Jean's love life has been rather uneventful so far. Not that she lacks heart or imagination. On the contrary, she has experienced heartbreak many times and has been hopelessly in love as well. Once, even with her older sister's boyfriend. It's clear that she can't confide in anyone about this. Except for her hatbox. To clarify her feelings, Lara Jean writes a goodbye love letter each time, pouring her heart out, and places it inside. These five letters are a closely guarded secret. Until the day, in a mysterious turn of events, each letter reaches its intended recipient, and Lara Jean's purely imaginary love life spirals completely out of control.
