XO, Kitty Season 3: Release Date Locked, Trailer Signals a Season of Growth, Goodbyes, and Consequences

The wait is nearly over for fans of Netflix’s charming spin-off from the To All the Boys I’ve Loved Before universe. XO, Kitty Season 3 has an official release date set for March 2026, with production wrapped in Seoul back in July 2025. As senior year beckons at the Korean Independent School of Seoul (KISS), the newly dropped official trailer makes one thing crystal clear: this isn’t just another round of fluffy teen romance. It’s about growing up, learning to let go, and confronting the real fallout from the impulsive choices Kitty Song Covey made in her chaotic junior year.

Anna Cathcart returns as the ever-optimistic Kitty, whose journey from wide-eyed newcomer to seasoned (yet still messy) senior has been the heart of the series. Season 2 ended on a whirlwind: Kitty’s exploration of her queer identity led to a kiss with Yuri (Gia Kim), straining friendships and contributing to Yuri’s breakup with Juliana (Regan Aliyah). Meanwhile, Kitty’s near-confession to Min Ho (Sang Heon Lee) turned into an invitation to join his family’s summer tour, leaving their slow-burn dynamic tantalizingly unresolved. The trailer picks up from there, bridging a transformative summer before plunging back into the halls of KISS—halls that now feel heavier with the weight of consequences.

This season marks a tonal shift toward maturity. Showrunner Valentina Garza has steered the story into deeper waters, exploring themes of identity, accountability, and transition. Kitty must face the ripple effects of her actions: the fractured friend group after her kiss with Yuri, the emotional baggage from her on-again-off-again with Dae (Minyeong Choi), and the lingering tension with Min Ho. The trailer teases vulnerable moments—like quiet conversations under Seoul’s skyline—highlighting how past choices haunt the present. It’s not all heartbreak; there’s growth, too, as characters grapple with college applications, family expectations, and the bittersweet reality of things ending.

Min Ho’s arc promises particular depth. Sang Heon Lee’s charismatic portrayal of the guarded rich kid has evolved from antagonist to fan-favorite love interest. After Season 2’s heartbreaks, the summer tour with Kitty offers a chance to explore their chemistry outside school pressures. Trailer glimpses suggest intimate, rain-soaked hugs and rooftop confessions, building on their enemies-to-friends-to-maybe-more trajectory. Yet the “heavier” atmosphere implies complications—perhaps Min Ho’s family dynamics or Kitty’s unresolved feelings elsewhere—will test whether they can truly move forward.

Yuri’s return adds layers of complexity. Gia Kim shines as the confident yet vulnerable heiress navigating her own identity and family fallout. The trailer hints at confrontations where Yuri forces Kitty to acknowledge avoided truths, potentially reigniting sparks or closing chapters for good. This subplot underscores the season’s focus on letting go: of crushes, friendships strained by secrets, and the naive belief that love fixes everything.

The ensemble remains a strength. Anthony Keyvan’s loyal Q, Peter Thurnwald’s Alex, and others provide comic relief and support amid the drama. New faces—Sule Thelwell as Marius, Soy Kim as Yisoo, and Christine Hwang as Gigi—inject fresh energy, promising new rivalries, alliances, and romantic subplots. Filmed authentically in Seoul, the show continues blending K-drama flair with American rom-com heart, now tempered by real-world teen struggles like self-acceptance and impending adulthood.

Creator Jenny Han’s influence ensures emotional authenticity. From Kitty’s initial quest to connect with her late mother’s past, the series has grown into a nuanced portrait of a young woman learning that love—romantic, platonic, or self—often requires painful honesty and release. The trailer’s montage of laughter turning to tears, hugs amid arguments, and characters staring at uncertain futures captures this perfectly.

With strong global viewership pushing renewals (Season 2 topped charts in dozens of countries), XO, Kitty has earned its place as a modern coming-of-age gem. March 2026 can’t come soon enough for fans ready to watch Kitty face the music of her choices. This season isn’t about fairy-tale endings; it’s about the messy, meaningful process of becoming who you’re meant to be—one heartbreak, forgiveness, and brave step at a time.

As the trailer fades on a group shot against the Seoul skyline, one message lingers: growing up means letting go, but it also opens doors to what’s next.
