The Covey sisters’ universe is expanding once again. After three seasons of romantic rollercoasters at the elite KISS academy in Seoul, Kitty Song Covey is trading hanboks and high-school hallways for the bustling streets of London in what could be the show’s most transformative chapter yet. Netflix has yet to officially confirm Season 4, but strong fan demand and production rumors point to a 2027 release that relocates the action to a prestigious UK university setting.

Season 3 ended on a hopeful high note: Kitty and Min Ho finally confessed their love at the train station, boarded a flight to Portland together, and seemed ready to face the future as a couple. Kitty’s acceptance into NYU loomed large, promising new adventures beyond Korea. Yet the teaser energy around Season 4 suggests that “happily ever after” is far from guaranteed. Production leaks hint at a title shift toward “XO London,” with Kitty navigating international university life, culture clashes, and complicated new relationships.

One of the biggest draws is the potential return of Lana Condor as big sister Lara Jean Covey. A cameo could bring much-needed sisterly advice as Kitty grapples with her mother’s hidden London history — a secret discovery that reshapes how Kitty views her own identity and family legacy. This emotional layer adds depth to the light-hearted rom-com tone the series is known for.

Min Ho, played by the charismatic Choi Min-young, isn’t fading into the background. Reports suggest he follows Kitty to the UK, sparking hilarious and heart-wrenching culture clashes. Their established chemistry will be tested by distance, new temptations, and the pressures of young adulthood. Enter a charming British rival determined to win Kitty’s heart — setting up what fans are already calling the franchise’s most complicated love square yet.

The move from Seoul to London brings fresh visuals, bigger fashion moments, and evolving friendships. Kitty’s core group faces power shifts as they transition out of high school. Themes of self-discovery, chasing dreams versus chasing ghosts, and building a future on your own terms take center stage. Expect witty banter, emotional confrontations, and the signature heartfelt letters that defined the To All the Boys universe.

Anna Cathcart continues to shine as the bubbly yet resilient Kitty, whose optimism often leads to messy but relatable decisions. The supporting cast, including the fan-favorite ensemble from KISS, may appear in limited capacities or through flashbacks as the story embraces this new international phase. The shift also opens doors for crossover potential with the broader Jenny Han cinematic world.

While Netflix remains silent on official renewal, the momentum is undeniable. Season 3’s strong performance and the open-ended Portland trip provide perfect launching pads for university arcs. If greenlit soon, fans could see Kitty’s London adventures as early as summer 2027. Whether she chooses stability with Min Ho, explores sparks with the new British interest, or focuses entirely on self-growth remains the biggest question hanging over the season.

XO, Kitty has always excelled at blending feel-good romance with genuine coming-of-age struggles. Season 4’s rumored London setting promises to elevate the stakes — literally and figuratively — as Kitty steps into a bigger world. From foggy Thames walks to university parties and family revelations, this chapter could redefine the series while staying true to its warm, letter-writing heart.

For longtime fans who grew up with Lara Jean and fell for Kitty’s adventurous spirit, this potential new season offers both nostalgia and exciting evolution. The Covey family’s story of love, loss, and fearless pursuit of happiness continues — now with a British twist that might just steal Kitty’s heart… or break it all over again. As the teaser vibe suggests, nothing stays simple when XO, Kitty heads to London.
