The global sensation XO, Kitty is gearing up for what could be its most intense and heartfelt season yet. The official trailer for Season 4 has fans buzzing with excitement and theories after its recent release, teasing a senior year at KISS filled with messy romance, resurfacing secrets, and high-stakes drama that builds on the beloved spin-off from the To All the Boys I’ve Loved Before universe.

The trailer opens with Kitty Song Covey (Anna Cathcart) navigating the final stretch of her senior year at the prestigious Korean Independent School of Seoul (KISS). After the emotional rollercoaster of Season 3 — where she finally seemed to solidify her relationship with Min Ho (Sang Heon Lee) — the new season wastes no time ramping up the complications. Distance, new temptations, and lingering feelings threaten to pull the couple apart just as they were getting closer.

Key moments in the trailer highlight:

  • Kitty balancing academics, friendships, and her evolving romance while facing major life decisions about her future after KISS.
  • Min Ho dealing with family pressures and personal growth as he supports Kitty through her challenges.
  • The return of familiar faces and introduction of new characters that stir jealousy and create explosive love triangles.
  • Emotional confrontations between Kitty and her friends, including unresolved tensions with characters like Yuri and Juliana.
  • A dramatic gunshot in the final seconds that leaves viewers speculating who is in danger and how the series might conclude Kitty’s journey.

The series continues to shine with its signature blend of heartfelt coming-of-age moments, cultural clashes, and swoon-worthy romance. Anna Cathcart brings even more depth to Kitty’s character as she transitions from wide-eyed newcomer to a young woman ready to face adulthood. The chemistry between Kitty and Min Ho remains electric, with the trailer packed with tender kisses, heated arguments, and quiet moments that capture the bittersweet reality of first love meeting real-world pressures.

XO, Kitty exploded in popularity as a charming, diverse extension of the To All the Boys franchise. Season 4 appears ready to deliver the emotional payoff fans have been waiting for, potentially wrapping up Kitty’s time in Seoul while leaving room for future stories. The trailer hints at bigger crossovers, including possible appearances or references to Lara Jean and Peter Kavinsky, raising excitement for a potential family-focused finale or spin-off.

Fans are already flooding social media with predictions about the gunshot scene, debates over Kitty’s endgame romance, and hopes for a satisfying graduation storyline. Many are planning full series rewatches to spot every clue leading into this new chapter. The trailer’s high production value, stunning Seoul visuals, and pulse-pounding soundtrack signal that Season 4 will be the most cinematic and emotionally charged yet.

Whether you discovered the series through viral clips or have followed Kitty’s adventures from the beginning, Season 4 looks set to deliver the perfect mix of laughter, tears, and growth. The story explores deeper themes of identity, friendship, cultural identity, and the courage to choose your own path — all while keeping the lighthearted charm that made the show a hit.

Streaming on Netflix, XO, Kitty Season 4 is expected to premiere later in 2026.
