Netflix’s beloved spin-off XO, Kitty continues to captivate audiences as anticipation mounts for its third season, slated for an early 2026 release. A circulating teaser description—”XO KITTY: SEASON 3 – OFFICIAL TRAILER (2026) | Do You Promise…? Kitty and Min Ho’s shocking Season 3 wedding turns the entire XO Kitty storyline upside down. Love, destiny, and emotional chaos collide in Netflix’s most unexpected romantic twist ever.”—has sent fans into a frenzy, imagining a bold leap where Kitty Song Covey (Anna Cathcart) and Min Ho (Sang Heon Lee) take their slow-burn romance to unforeseen heights.

The series, created by Jenny Han as an extension of the To All the Boys I’ve Loved Before universe, follows the irrepressible Kitty as she navigates life, love, and self-discovery at the Korean Independent School of Seoul (KISS). Season 1 saw her chasing long-distance boyfriend Dae (Minyeong Choi) across the globe, only to uncover secrets and spark unexpected connections. Season 2, which premiered in January 2025, escalated the drama with multiple love interests, family revelations, and a cliffhanger that left Kitty confessing her feelings to the charismatic Min Ho just as summer break loomed.

Production on Season 3 wrapped in July 2025 in Seoul, with Netflix confirming the renewal back on Valentine’s Day. The upcoming chapter marks the show’s first summer episode, picking up with Kitty impulsively joining Min Ho on a family tour—a setup ripe for romantic tension and heartfelt growth. Returning cast members include Gia Kim as Yuri, Anthony Keyvan as Q, Regan Aliyah as Juliana, and Peter Thurnwald as Alex, alongside new additions like Sule Thelwell (Marius), Soy Kim (Yisoo), and Christine Hwang (Gigi). Hojo Shin has been promoted to series regular as Jiwon.

While no official trailer has been released yet—typically arriving closer to premiere—the viral concept teases a narrative where a simple promise spirals into chaos. Fans speculate that Kitty and Min Ho’s summer adventures could culminate in a whirlwind wedding proposal or ceremony, flipping the storyline on its head. The tagline evokes high-stakes emotion: “Do You Promise…?” suggests vows exchanged amid doubt, with love clashing against destiny in Netflix’s signature blend of teen angst and K-drama flair.

This potential twist aligns with the show’s history of subverting expectations. Kitty, the ultimate matchmaker from the original films, has evolved from wide-eyed optimist to a young woman grappling with complicated feelings. Her enemies-to-lovers dynamic with Min Ho—marked by banter, vulnerability, and undeniable chemistry—has been a fan favorite, often dubbed “Kinho.” A wedding, even if impulsive or symbolic, would represent the ultimate romantic escalation, forcing confrontations with exes like Dae and Yuri, family expectations, and Kitty’s own fears about commitment.

Showrunners have promised “plenty of romance, friendship, adventure…and kissing,” hinting at deeper explorations of identity and relationships. With Kitty’s scholarship renewed for another year at KISS, Season 3 will balance summer escapades with senior-year pressures, including college decisions and lingering secrets from her mother’s past. New characters could introduce fresh rivalries or alliances, complicating the central romance.

The series has proven a global hit, drawing millions of views and topping charts in numerous countries. Its mix of cultural immersion, diverse representation, and relatable coming-of-age themes has earned praise, with Season 2 boosting rewatches of the original To All the Boys films. Comparisons to heartfelt YA dramas like Heartstopper or Never Have I Ever underscore its appeal in delivering swoon-worthy moments alongside authentic emotional depth.

Although the wedding teaser appears to stem from fan creativity—mirroring viral concepts that have amassed millions of views online—the idea resonates with the show’s trajectory. Kitty and Min Ho’s journey from rivals to confidants has built toward something profound, and a shocking twist could deliver the emotional payoff fans crave. Will destiny favor their union, or will chaos unravel it all?

As post-production continues, viewers are rewatching Seasons 1 and 2, dissecting behind-the-scenes glimpses from the cast. With an expected 2026 debut, likely in the spring to align with school themes, XO, Kitty Season 3 is shaping up to be the most unpredictable yet. In a world of letters, long-distance crushes, and heartfelt promises, one unexpected vow could change everything—proving that sometimes, love’s greatest risks lead to its biggest rewards.
