'To All The Boys' spinoff series 'XO, Kitty' confirmed: 'I bet you thought the story was over'

E! News relayed the series logline: "Teen matchmaker Kitty Song Covey thinks she knows everything there is to know about love. But when she moves halfway across the world to reunite with her long-distance boyfriend, she'll soon realize that relationships are a lot more complicated when it's your own heart on the line."

"To All The Boys I've Loved Before" premiered in August 2018 and starred Lana Condor as teenager Lara Jean Covey. Her life is turned upside when Kitty, her witty little sister, secretly sends out letters she had written to every crush she's ever had. 

That leads to a fake relationship with school jock Peter Kavinsky (Noah Centineo), and it blossoms into an adorable first love through the sequel, "To All The Boys: P.S. I Still Love You" (2020), and the third and final installment, "To All The Boys: Always and Forever," from this past February.

In "Always and Forever," Kitty falls for a boy she met during the Covey family vacation to Korea, which sets up "XO, Kitty."

Deadline exclusively reported that the spinoff series was in the works in March.
