XO, Kitty isn’t signing off just yet.

The Netflix original series — a spinoff of the popular To All the Boys film franchise — follows Kitty Song-Covey (Anna Cathcart) as she moves to Seoul to attend the Korean Independent School of Seoul (K.I.S.S.) and reunite with her long-distance boyfriend, Dae (Choi Min-young).

Their reunion proves to be more complicated and dramatic than romantic, leading Kitty to find new friends — and romances — while building a life in the South Korean city.

“Immediately when she gets there, within seconds after she sees [Dae], that’s all kind of thrown out the window,” Cathcart revealed to PEOPLE in May 2023. “And she’s thrown upside down into this whole new world that she was not expecting to find in Korea.”

The first season premiered in May 2023, with the second following in January 2025 — but what is in store for season 3?

Here’s everything to know about XO, Kitty season 3, including who is being added to the cast and when fans can expect to start a new year at K.I.S.S.

Yes, XO, Kitty has been renewed for a third season. Netflix made the announcement in a video posted online on Feb. 14.

In the clip, Cathcart accepts a delivery of a bouquet of roses, reading a card that says: “Roses are red, violets are blue, there’s a third season of XO, Kitty in store for you!”

She then reaches into a gift bag, revealing a season 3 script. “It’s official! Season 3 of XO, Kitty is in the works,” she says ecstatically.

Which cast members are returning for XO, Kitty season 3?

The series is also adding three new cast members to the upcoming season: Sule Thelwell, Soy Kim and Christine Hwang.

“Grateful beyond words to join the XO, Kitty family! It’s been nothing short of magical,” Kim wrote on Instagram in July 2025. “The cast and crew are not only wildly talented, but endlessly kind. I feel so lucky to be part of something special. And witty. And charming.”

What happened at the end of XO, Kitty season 2?

Season 2 ended with Kitty scoring a scholarship to K.I.S.S., securing her return to the school for her senior year.

In the finale, Kitty is about to confess her feelings to Min Ho (Sang Heon Lee), before he leaves to spend his summer on tour, with his dad, and older brother, pop star Joon Ho (Peniel Shin). The two say goodbye and embrace, almost sharing a kiss. After Min Ho walks away, Kitty yells out, asking if she can join him on the tour. He smiles and nods for her to come along.

“I know we left fans on a cliffhanger at the end of Season 2 but I can promise season 3 will be worth the wait, including our first summer episode,” season 2 showrunner Jessica O’Toole said at the time of the renewal, per Deadline. “Not to mention plenty of romance, friendship, adventure … and kissing. Lots of kissing.”

According to Deadline, Valentina Garza, who wrote the season 2 finale and was a writer on seasons 2 and 3, took over as showrunner for the upcoming season.
