To All the Boys I’ve Loved Before follows sixteen-year-old Lara Jean Song who keeps love letters in a hatbox given to her by her mother. These are not letters received from others, but ones she wrote herself, one for each boy she ever loved. Normally, these letters are her private outlet for expressing feelings she’d never voice in real life. However, her life spirals when these letters are unexpectedly mailed out, turning her once imaginary love life into chaos.
