Calling all rom-com and K-drama fans, XO, Kitty is your next heart-fluttering escape. In 2023, Netflix revived To All the Boys I've Loved Before with the hit spinoff show, following the youngest Song Covey sister, Kitty. The series created by book author Jenny Han begins four years after To All the Boys: Always and Forever, following Kitty as she gets the chance to attend the elite Korean Independent School of Seoul, her late mother's alma mater, for her junior year.
The first two seasons of the romance series follow Kitty through her first two semesters at KISS, where she comes to new realizations about her matchmaking skills, her sexuality, and her deceased mother's side of the family. Following season 2's love triangle-filled chapter of Kitty's coming-of-age journey, the show was renewed for a third season, which completed filming in July 2025.
For the series filmed primarily in Seoul, Han has tapped a cast of up-and-coming actors from American television, Korean dramas, and even international theatre. Read on to meet (and follow) the cast of XO, Kitty, including the new stars who will appear in season 3.
Anna Cathcart as Kitty Song Covey
Kitty is 16-years-old when we catch up with her in the spinoff, and living in Portland with her dad and stepmom. She's been virtual pals with Dae since they met at age 12, and the pair are now in a committed long-distance relationship. All of that changes when Kitty is admitted to KISS, where she learns more about both her deceased mother and her adoring boyfriend. Though she and Dae ultimately weren't meant to be, Kitty's still hopeful about finding her happily-ever-after.
Anna Cathcart, 22, has played Kitty since the first To All the Boys film was released in 2018. The 19-year-old actress has also starred in the PBS Kids series Odd Squad, and the Disney films Descendants 2 and 3, as well as appearing in a short role on the ABC series Once Upon a Time.

Minyeong Choi as Dae Heon Kim
At the start of XO, Kitty, Dae and Kitty have been long-distance dating since they met at Namsan Tower four years ago.

Choi Minyeong, 22, got his start as a child actor in stage musicals and several beloved K-dramas, including W: Two Worlds Apart, Strong Woman Do Bong-soon, Chicago Typewriter, Mr. Sunshine, and Itaewon Class, and Twenty-Five Twenty-One.

Sang Heon Lee as Min Ho
Wealthy and privileged Min-ho seems cold and bratty on the surface, but he's fiercely loyal to his friends and family, including his longtime friend Dae. He doesn't have the best reaction when Kitty shows up and changes the dynamics of his friend group.
