In the third season of the charming teen rom-com XO, Kitty, our titular protagonist, worries about the future. In the newly released season on Netflix, Kitty Song-Covey (Anna Cathcart) has returned for her senior year at the Korean Independent School of Seoul (a.k.a. KISS) and started a serious relationship with her crush, Min-ho (Sang Heon Lee). But, with the end of high school looming and a question mark about what might come next, Kitty begins to feel anxious about what the future might hold. Will she stay in Korea, return to the U.S., or chart a course somewhere else?
By the season’s end, Kitty seems poised to return to the U.S. after she finishes her senior year, having been accepted early admission to New York University. However, nothing is ever predictable in the romance series, spun off from the beloved To All the Boys I’ve Loved Before movies. Especially because, unlike To All the Boys, XO, Kitty doesn’t have books that it's based on. With lots up in the air, below we're breaking down everything we know about XO, Kitty season 4.

Has 'XO, Kitty' been renewed for season 4?
XO, Kitty has performed consistently well on Netflix. Its first season, released in 2023, snagged over 14 million views in its first week, finishing only behind the Bridgerton series Queen Charlotte in the rankings. According to the Netflix Engagement Report for the first half of 2025, when XO, Kitty season 2 premiered, the series racked up more than 35 million views, making it the 18th most-watched series on the streamer in that period. If viewership for the third season stays high, then there is no reason why Netflix shouldn’t renew the original series for a fourth season. Season 3 showrunner Valentina Garza told Deadline about the possibility: “I know that all of our fans would love to see that. We’re just gonna have to wait and see what happens. We’re very excited to continue to see our characters learn and grow.”

Either way, look for streaming numbers, especially in that first week and month after release, to determine if XO, Kitty will continue.
It's possible there could be a quick turnaround between seasons 3 and 4.
When will 'XO, Kitty' season 4 come out?
Should XO, Kitty be renewed, a new season is likely in early 2027. While there was a two-year gap between seasons 1 and 2, which was most likely a result of the Writers Guild of America strike, there was only about a year between seasons 2 and 3. Season 2 was released on Netflix in January 2025, and season 3 came out in April 2026. If Netflix follows that same production and release pattern, we should be hanging with Kitty and friends again around springtime next year.
Season 3 sees relationship changes for many couples, including Juliana (Regan Aliyah) and Praveena (Sasha Bhasin).
What would 'XO, Kitty' season 4 be about?
XO, Kitty season 3 unfolds as if there could be a fourth. While the season’s conclusion—which sees Min-ho accompanying Kitty home to Portland following their reconciliation—could act as a satisfying series conclusion, there is definitely more story to tell. What will Kitty’s dad (John Corbett) think of Min-ho? Will Kitty manage to lock in for the final semester of her high school career and graduate? Will she really plan to go to NYU and leave Seoul behind? Either way, will she and Min-ho stay together?
That's ample material to explore. As for Kitty herself, Cathcart weighed in on what she thinks fans can expect from the Kitty-Min-ho ship going forward. While speaking with Refinery29, she admitted that she thinks they're "endgame."
The star said, "I definitely think if you ask them on that airplane, they would both say they are endgame...In that moment, they feel closer than ever and more excited than ever about the future; so much of the theme of season 3 is embracing the unknown and not knowing what’s gonna happen next and finding the joy in that versus the fear in that. And I think that really applies to their relationship as well."
Her co-star, Lee, also told the outlet that "there will be an ending" to the couple's saga, though he remained tight-lipped about what might be next. "You get to see that they started this relationship, but sometimes all good things come to an end. And even if it’s something bad, there will be an ending," he said. "But also, I feel that the audience should realize it’s okay; this is how life works. But there’s always a better thing to look forward to as well. It’s not the end of the world."

Kitty and Min-ho are hardly the only characters with more to explore in season 4; there is also the vibrant ensemble cast to consider. Yuri (Gia Kim) and Juliana (Regan Aliyah) ended season 3 by tentatively turning back towards one another following Juliana’s breakup with Praveena (Sasha Bhasin). Where will Dae (Minyeong Choi) go to college now that his dream of going to Seoul National University is dead? And will Q (Anthony Keyvan) and Jin (Joshua Lee) survive graduation as a couple? How will Alex (Peter Thurnwald) and Jiwon (Hojo Shin) navigate their relationship once their baby is born?
A fourth season could also include a proper update on To All the Boys characters Lara Jean (Lana Condor) and Peter’s (Noah Centineo) relationship. While both Peter and Lara Jean have appeared on XO, Kitty, we have yet to see them both together on the show. A fourth season of XO, Kitty could be the perfect time to depict an engagement or even a wedding between the two fan-favorite characters. "Kitty and Lara Jean’s arcs are really interconnected,” Garza told Deadline. “They’re both able to give to each other and learn and grow through each other. Kitty gives Lara Jean the courage to take that step to turn in her book to her publisher. So it’s a very mutual relationship.”
Season 4 will also be an important one in terms of XO, Kitty’s long-term future. Will Netflix decide to wrap up the show at the end of Kitty’s high school experience, or will the story continue into her college years and beyond? Traditionally, high school-set shows don’t tend to make the transition to a post-graduation life so smoothly, but if anyone can do it, it’s Kitty Song-Covey.
Lana Condor reprised her role as Lara Jean from the To All the Boys... movies in season 3, and could return again in season 4.
Who in the 'XO, Kitty' cast will be back for season 4?
Other than the departure of Yunjim Kim, who plays Yuri’s mom, most of the main cast of XO, Kitty has stayed gloriously the same, with a few additions. No season of XO, Kitty would be complete without the main cast members Cathcart, Sang, Kim, Choi, and Keyvan, so we can certainly expect to roam the halls of KISS with them yet again.
