XO, Kitty Season 4: Release Date, Cast, and Renewal Updates

Netflix has not yet confirmed a fourth season of the romantic comedy drama XO, Kitty, following the release of the series’ third season on April 2, 2026. The show, a spinoff of the To All the Boys I’ve Loved Before film franchise, concluded its most recent installment with the primary characters facing the end of their senior year at the Korean Independent School of Seoul (KISS).

Season 3 consisted of eight episodes, released simultaneously on April 2, 2026. The season focused on Kitty Song Covey, played by Anna Cathcart, as she navigated her final year of high school in Seoul, balancing academic pressures, long-distance relationship challenges, and the discovery of her late mother’s secret life.

Season 3 Conclusion and Narrative Arc

The third season followed a trajectory of interpersonal conflict, including rumors of cheating and loyalty issues among the student group. The narrative culminated in the finale, where Kitty and Min Ho Moon, played by Sang Heon Lee, reconciled after a mid-season breakup. The season ended with Kitty deciding to embrace the unknown of her future, with the final moments showing the couple traveling to visit Kitty’s hometown in Portland.

While the finale provided some resolution for the central couple, it left several plot threads open. Kitty has one semester remaining at KISS, and she has made the decision to eventually follow her sister to New York University (NYU) after that final term.

Renewal Status and Production Outlook

As of April 10, 2026, Netflix has not made an official announcement regarding the renewal of the series for a fourth season. Showrunner Valentina Garza has remained diplomatic regarding the future of the characters, stating in an interview that the production team is currently focusing on the release of the third season.

Historically, Netflix has announced the renewal status for XO, Kitty approximately one month after a season premieres. This timeline suggests that a decision may be reached by early May 2026. Some reports indicate that the third season may not have performed as strongly as the first two seasons in terms of profit, which could impact the decision regarding a renewal.

If the series is renewed, industry estimates suggest a new season could potentially arrive in early 2027, accounting for a production window of six to eight months. This would follow a pattern of gaps between seasons, such as the two-year interval between the first and second seasons.

Potential Cast and Plot Developments

Should a fourth season be greenlit, the core ensemble is expected to return. This includes Anna Cathcart as Kitty, Sang Heon Lee as Min Ho, Choi Min-yeong as Dae Kim, Anthony Keyvan as Q Shabazian, and Gia Kim as Yuri Han. Supporting roles such as Principal Jina Lim and Professor Daniel Lee are also likely to recur.

Potential plot directions for a future season include the transition from high school to college, specifically Kitty’s move to New York City. There is also the possibility of exploring Min Ho’s journey and the dynamics of the couple’s relationship as they move beyond the environment of KISS. Other characters like Dae, Q, and Yuri would likely remain involved to resolve remaining narrative arcs.

Critical Reception

The series has seen varying levels of critical and audience reception. The first two seasons were highly praised by fans of the original film series, with the first season earning an 82% Tomatometer score and the second season earning 83% on Rotten Tomatoes. However, the third season has received a more mixed response from viewers. The series currently holds a 6.6 out of 10 rating on IMDb based on over 20,000 viewer reviews.
