Netflix’s XO, Kitty has reached a narrative crossroads with season 3, as Kitty Song Covey embarks on her senior year at KISS. With the series’ central arc approaching its natural conclusion, the burning question for fans is whether a fourth season will materialize to continue Kitty’s journey beyond high school.
The arrival of XO, Kitty season 3 marks a significant milestone for the To All the Boys spin-off. After two seasons navigating the complexities of love and identity at the Korean International School, Kitty Song Covey, portrayed by Anna Cathcart, is now a senior. Her mission? To complete a “Senior Sunset List” that encompasses college decisions, cultural reconnection with her Korean family during Chuseok, and finally defining her relationship with Min Ho Moon, played by Sang Heon Lee.
This senior-year focus inherently raises the stakes for the show’s future. A fourth season could logically explore Kitty’s final semester at KISS or pivot to her college experiences, but the creative team has not yet confirmed any plans. The official synopsis for season 3 hints at unresolved tensions: Kitty’s perfect plan is upended by “surprise revelations,” forcing her to “learn to embrace the unexpected.” This narrative openness leaves the door ajar for continuation, yet also suggests a potential endpoint.
The Renewal Status: Awaiting Netflix’s Verdict
As of now, XO, Kitty has not been officially renewed for a fourth season. However, the show’s renewal pattern provides a clue. Season 2 premiered on January 16, 2025, and Netflix announced the season 3 pickup by Valentine’s Day that same year. If a similar timeline applies, fans could expect a season 4 announcement in the coming months following season 3’s release. The streaming giant has historically been supportive of the franchise, which includes the original To All the Boys film trilogy, but viewership metrics for season 3 will be the ultimate deciding factor.
Expected Cast: The Core Group Likely Returns
While formal casting announcements for season 4 are pending, all signs point to the return of the established ensemble from season 3. Key cast members expected to reprise their roles include:
- Anna Cathcart as Kitty Song Covey
- Minyeong Choi as Dae
- Gia Kim as Yuri
- Sang Heon Lee as Min Ho Moon
- Anthony Keyvan as Q
- Regan Aliyah as Juliana
- Hojo Shin as Jiwon
- Peter Thurnwald as Alex
- Joshua Lee as Jin
- Sasha Bhasin as Praveena
- Michael K. Lee as Professor Lee
- Philippe Lee as Mr. Moon
- Jocelyn Shelfo as Madison
- Han Bi Ryu as Eunice
- Sunny Oh as Mihee
Any potential new additions would likely be announced alongside a renewal, but the core friend group and family members are integral to Kitty’s story and are anticipated to remain central.
Plot Possibilities: College or a Final Semester at KISS?
The show’s structural approach to Kitty’s high school tenure is crucial for predicting season 4. Season 1 covered the first half of her junior year, while season 2 completed the second half. Season 3 jumps to her senior year. A fourth season could either:
- Depict Kitty’s final semester at KISS, resolving her “Senior Sunset List” items and her relationship with Min Ho.
- Transition to Kitty’s college life, potentially introducing new settings, characters, and challenges while maintaining ties to her KISS friends.
The official season 3 synopsis emphasizes Kitty’s desire to “define her relationship with Min Ho. For real this time,” implying that their romance may reach a definitive conclusion—either a lasting commitment or a meaningful breakup—by the season’s end. This relationship arc is a cornerstone of the series, and its resolution would heavily influence whether a season 4 feels narratively necessary.
Fan Theories and the Franchise Context
The XO, Kitty fan community is actively speculating about the show’s fate. Theories range from a college-focused season 4 to a limited series wrap-up. The broader To All the Boys franchise, which concluded with the third film in 2021, provides a template: the original series ended with Lara Jean’s college acceptance, suggesting a similar full-circle moment for Kitty is possible. Fans are particularly invested in Kitty and Min Ho’s relationship, hoping for a satisfying payoff after seasons of will-they-won’t-they tension. Any renewal announcement would need to address these long-running character arcs to maintain audience satisfaction.
Ultimately, the decision rests on Netflix’s strategic priorities and season 3’s performance data. For now, viewers can stream season 3 to see how Kitty’s senior year unfolds and whether her story demands further chapters.
