The senior year at the Korean Independent School of Seoul (K.I.S.S.) has officially come to a close with the release of XO, Kitty Season 3. As Katherine "Kitty" Song Covey navigates her final semester in South Korea, the stakes have never been higher—not just for her academic future, but for the complex web of relationships she has woven since she first stepped off the plane in Seoul. This season represents a significant maturation for the franchise, moving past the initial "fish out of water" tropes and into the bittersweet reality of adulthood, early decision letters, and the realization that love isn't always a neatly organized spreadsheet.

The Senior Year Journey and the Summer of Min Ho

Season 3 picks up with a departure from the typical school setting, initially focusing on the aftermath of the Season 2 cliffhanger. Kitty’s decision to join Min Ho on his family’s high-profile summer tour set a specific tone for the year. It allowed for a deeper exploration of Min Ho’s world—one dominated by paparazzi, celebrity expectations, and the shadow of his K-pop star brother, Joon Ho. This prologue served a dual purpose: it solidified the chemistry between Kitty and Min Ho while highlighting the vast cultural and lifestyle gaps between a girl from Portland and a global socialite.

Returning to K.I.S.S. for the fall, Kitty is no longer the girl chasing a boy; she is a girl chasing a legacy. Armed with her "Senior Sunset List," she attempts to balance her desire for meaningful memories with the looming pressure of college applications. The list includes everything from celebrating Chuseok with her Korean relatives to visiting Lotte World, but the most daunting item remains defining her relationship with Min Ho. This central conflict drives the narrative forward, questioning whether their connection can survive outside the vacuum of their shared adventures.

The Return of Lara Jean: A Full Circle Moment

Perhaps the most talked-about moment of Season 3 is the return of Lana Condor as Lara Jean Song Covey. Her cameo is handled with surgical precision, occurring at a moment of peak emotional crisis for Kitty. When Kitty finds herself overwhelmed by the complexities of her feelings for Min Ho and the fear of making the wrong choice for her future, Lara Jean arrives in Seoul to provide more than just sisterly comfort.

Lara Jean’s presence bridges the gap between the original To All the Boys trilogy and this spin-off. Her advice to Kitty—reminding her that the path to self-discovery is rarely linear—reflects her own growth since her days at Adler High. This interaction is crucial because it validates Kitty’s struggle; even the girl who seemingly has the "perfect" romance knows that following one's heart is a terrifying, messy endeavor. Lara Jean’s return isn't just fan service; it’s a passing of the torch that encourages Kitty to embrace the unexpected rather than trying to plan every second of her life.

Deep Dive into the Ending: Train Stations and Business Class

The finale of Season 3, Episode 308, delivers the kind of high-octane romantic drama that has become the hallmark of the series. The setting is Kitty’s 18th surprise birthday party—a celebration that quickly turns into a crossroads for every major character.

Min Ho, despite his earlier reservations and a brief breakup centered on trust issues, goes above and beyond to honor Kitty’s late mother, incorporating her favorite flowers and themed gifts into the celebration. However, the real climax happens not at the party, but at Seoul Station. In a mirror of the Season 1 finale’s airport chase, Min Ho rushes to catch Kitty before she departs for the winter break.

Their confrontation at the station is raw and honest. Min Ho confesses his love, acknowledging that while he doesn't want to stand in the way of her future at NYU, he cannot imagine his own life without her in it. The passionate kiss they share amidst the bustle of the station signifies a shift in Kitty’s philosophy. She finally stops trying to "plan" their relationship and decides to let things happen naturally. The final shot of the season—Kitty and Min Ho sitting together in business class on a flight to Portland—suggests that while their academic paths may diverge, their emotional lives are now irrevocably linked. Min Ho meeting Kitty’s father, Dan Covey, marks a massive step in their relationship, bringing the story back to the family roots in Oregon.

The Supporting Cast: Heartbreak and New Beginnings

While Kitty’s romance takes center stage, the supporting characters at K.I.S.S. face their own seismic shifts. The evolution of Q and Jin’s relationship provides a grounded look at the challenges of maintaining trust in a high-pressure environment. The introduction of Marius as a potential disruptor for Q initially felt like a standard love triangle, but the resolution—with Q realizing his deep-seated commitment to Jin—offers a refreshing take on loyalty. Jin’s willingness to forgive, albeit with a playful warning that Q will be "groveling forever," provides one of the season's lighter, more heartwarming conclusions.

Conversely, the storyline involving Jiwon and Alex Finnerty took a sharp turn into adult territory. The revelation of Jiwon’s pregnancy and the secret romance between the two faculty members (Alex and Jiwon) was the season's biggest shocker. This arc explored themes of responsibility and family legacy, particularly through Alex’s burgeoning relationship with his biological father, Professor Lee. Professor Lee’s promise to be the father he never had the chance to be for Alex, and a grandfather to the new baby, adds a layer of emotional depth to the series that balances out the teen romance. It also forces a career sacrifice, as Alex agrees to leave the university to protect Jiwon’s position, highlighting the theme of choice that permeates the entire season.

Dae and Eunice: Finding Peace Amidst Fame

Dae, Kitty’s original reason for coming to Seoul, finds himself in a significantly different place by the end of Season 3. His relationship with Eunice, which began as a tentative connection in Season 2, faces the intense pressure of Eunice’s sudden superstardom. The revelation that the pair lost their virginity to each other in Paris during the summer adds a layer of intimacy to their bond that explains Eunice’s erratic behavior early in the season. Her pregnancy scare and subsequent decision to step back from the limelight to reclaim her private life show a maturity that was previously unseen in her character. By attending Kitty’s birthday as a couple, Dae and Eunice represent a stable, quiet love that stands in contrast to the high-drama antics of the other pairings.

Production Shift: The Valentina Garza Era

From a technical and narrative standpoint, Season 3 benefited from the steady hand of showrunner Valentina Garza. Having written for previous seasons, Garza maintained the show's core DNA while injecting a more brisk, episodic pace that suited the "final year" theme. The visual storytelling remained vibrant, utilizing Seoul’s iconic landmarks like Namsan Tower and the Han River to enhance the romantic atmosphere. The soundtrack also deserves mention, blending Western pop with K-pop hits to reflect Kitty’s dual identity.

The decision to make Season 3 the final year at K.I.S.S. was a bold move that paid off. By setting a definitive end date for their time in Korea, the writers forced the characters to make difficult decisions. The looming deadline of college applications acted as a ticking clock, preventing the plot from stagnation. This season felt less like a continuation and more like a culmination of Kitty's adolescent journey.

What’s Next: Is Season 4 on the Horizon?

As of April 2026, Netflix has not officially confirmed a fourth season, but the ending of Season 3 leaves the door wide open. With Kitty accepted to NYU and Min Ho offered a prestigious job managing the girl group SOS 911, the potential for a "New York Chapter" is immense. Moving the setting to Manhattan would allow the show to explore the Song-Covey sisters' lives in a new light, possibly integrating Lara Jean and Margot more frequently.

However, the title XO, Kitty and its central premise were heavily tied to her experiences in Korea. If the show returns, it will likely have to find a way to keep the "K" in K.I.S.S. relevant, perhaps through Min Ho’s career or exchange programs. Regardless of whether we see these characters again, Season 3 provided a satisfying and emotionally resonant conclusion to Kitty’s time in Seoul. She arrived as a girl looking for her mother’s past and left as a young woman ready to build her own future.

Final Thoughts on Season 3

XO, Kitty Season 3 succeeded because it wasn't afraid to let its characters grow up. It tackled complex issues like unplanned pregnancy, the burden of celebrity, and the painful reality of long-distance relationships with a level of nuance that elevated the show above its teen-drama roots. The return of Lara Jean served as the perfect anchor, reminding audiences why they fell in love with this universe in the first place, while the evolution of the Kitty-Min Ho relationship proved that sometimes the best matches are the ones you never saw coming.

For fans who have followed Kitty Song Covey since her days of stealing letters in Portland, this season is a beautiful, bittersweet farewell to her high school years. Whether she’s in a dorm room in Seoul or a classroom in New York, Kitty remains the ultimate matchmaker—only this time, she finally found the most important match of all: herself.
