XO, Kitty Season 3 Release Date: When Will Kitty Return to KISS?

While Netflix has officially confirmed the show’s renewal, an exact release date for XO, Kitty Season 3 remains unannounced. However, based on the production timeline and industry patterns, a highly educated prediction can be made.

Predicted Release Window: Early 2026

Industry analysts and fan communities are currently predicting that XO, Kitty Season 3 will premiere on Netflix in early 2026, with some speculation pointing specifically toward a March 2026 debut.

This timeline is supported by several key factors:

• Renewal Date: The official renewal was announced in February 2025.
• Production Status: Crucially, it has been confirmed that filming for Season 3 has already wrapped in Seoul. This means the show is now moving into the post-production phase, which includes editing, sound mixing, and scoring.
• Historical Gap: The gap between the first two seasons was approximately a year and a half. Given the reported start of Season 3 filming in April 2025 and the recent wrap, a release in the first quarter of 2026 allows a realistic 9–12 months for the extensive post-production required for a high-quality international series.

Fans should keep a close eye on Netflix's official Tudum site and social media channels for a firm date, which is most likely to be announced in late 2025 or early 2026. The fact that the production phase is complete is the strongest indicator that the wait will not extend past the first half of the new year.

The Returning and New Faces: Full Confirmed Cast for Season 3

The ensemble cast is a major draw for XO, Kitty, blending Korean and Western actors to create a dynamic and diverse high school setting. Season 3 is set to bring back all the core characters whose storylines were left hanging, while also introducing three brand-new students who will undoubtedly shake up the status quo at KISS.

Confirmed Returning Main Cast

The following actors are confirmed to reprise their roles, continuing the complex relationships and friendships that define the show:

• Anna Cathcart as Kitty Song-Covey
• Sang Heon Lee as Min Ho Moon
• Choi Min-yeong as Dae Heon Kim (Dae)
• Gia Kim as Yuri Han
• Anthony Keyvan as Quentin (Q)
• Jocelyn Shelfo as Madison Miller (Madison)
• Regan Aliyah as Juliana (Juliana)

The return of Sang Heon Lee (Min Ho) and Choi Min-yeong (Dae) is particularly significant, as the core love triangle involving Kitty is the driving force of the series. The dynamic between Kitty, Min Ho, and Dae is expected to reach a new level of intensity in the upcoming season.

New Cast Members Joining KISS

To further complicate Kitty’s life and expand the world of the Korean Independent School of Seoul, Netflix has confirmed the addition of three new cast members for Season 3:

• Sule Thelwell will play the role of Marius.
• Soy Kim will join the cast as Yisoo.
• Christine Hwang has been cast as Gigi.

These new entities—Marius, Yisoo, and Gigi—are expected to introduce fresh subplots, new romantic rivals, or perhaps new friends to Q and Kitty, further enriching the topical authority of the series by exploring new corners of the KISS academy and the wider Seoul setting. The writers have a clear intention to keep the narrative fresh and unpredictable.

Plot Predictions and Shocking Cliffhangers for Kitty’s Next Chapter

Season 2 ended with multiple storylines unresolved, leaving fans with a dramatic cliffhanger that is ripe for exploration in Season 3. The new season will focus heavily on the fallout from these major decisions and the continuing theme of self-discovery for Kitty Song-Covey.

The Minho-Dae-Kitty Love Triangle Resolution

The central conflict remains Kitty’s complicated love life. The finale left the door open for a rekindled romance with Dae, but also a burgeoning, undeniable chemistry with Min Ho. Showrunner Jessica O’Toole has hinted that the series will continue to explore Kitty's feelings for both boys, and the introduction of new characters (Marius, Yisoo, Gigi) could further complicate the situation, potentially leading to a "love dodecahedron" rather than a simple triangle.

Kitty’s Journey of Self-Discovery and Identity

A major theme in the series is Kitty’s exploration of her own identity, including her bisexuality and her connection to her late mother’s past in Seoul. Season 3 is predicted to delve deeper into these personal issues, potentially introducing a new female love interest to challenge her feelings for Dae and Min Ho. Her struggle to balance her long-distance relationship with her American boyfriend and her real-life feelings at KISS will be a key emotional anchor.

The Future of KISS and the Han Family

The drama at the Korean Independent School of Seoul is far from over. Yuri Han's (Gia Kim) family drama and her relationship with Juliana (Regan Aliyah) will likely continue to be a significant subplot. The new students, Marius, Yisoo, and Gigi, may be connected to the school's administration or other key figures, bringing new academic and social challenges to Kitty and her friends Q, Dae, and Min Ho. The series has always been about more than just romance; it's about friendship, cultural adaptation, and academic pressure in a high-stakes environment.

With filming wrapped and a predicted early 2026 release, the anticipation for XO, Kitty Season 3 is building rapidly. The combination of a confirmed returning core cast, exciting new additions, and multiple unresolved cliffhangers ensures that the next installment will be a must-watch event on Netflix, continuing Kitty Song-Covey’s unforgettable adventure in South Korea.
