The cast includes Janel Parish and Lana Condor, who plays Lara Jean Covey, a girl who must deal with the aftermath of her secret when a hatbox of letters written to every boy she's ever loved are mysteriously mailed out.
Han took to Twitter to share her excitement and explain just why making this movie is so groundbreaking.
She also shared an adorable snap of herself with Janel Parrish (who will play Lara's older sister, Margot), Lana Condor (as Lara Jean), and Anna Cathcart (who will star as Lara's youngest sister, Kitty).

And because we are TRULY blessed, Han *also* shared a swoonworthy photo of Peter Kavinsky (played by Noah Centineo) and Lara Jean together.
