XO Kitty season 3: are Kitty and Min Ho end-game? Anna Cathcart and Sang Heon Lee unpack

Kitty Song‑Covey walks the halls of KISS this season like someone who’s been through the ringer — but she isn’t the wide‑eyed matchmaker we first met. Season 3 of XO, Kitty pivots from teenage crushes toward a quieter, messier coming‑of‑age: decisions about college, family strain, and the awkward, hopeful steps of growing up. If you loved the rom‑com spark of the earlier episodes, you’ll still find it here — but it shares the stage with a more thoughtful Kitty who’s learning to put herself first.

Spoiler alert: This piece discusses major plot points from XO, Kitty Season 3, including Kitty’s relationships and the season finale. Read on if you’ve finished the season or don’t mind spoilers.

Season 3 reframes Kitty: from love‑chasing to self‑discovery

Over three seasons and three To All the Boys films, Kitty’s character was often defined by her romantic flings and her role in other people’s stories. Season 3 changes that dynamic. Rather than centering each episode around a new crush, the series examines what Kitty wants for her life beyond any boyfriend — her ambitions, her friendships, and the choices that will shape her adult future.

Key shifts in the season include:

• Kitty’s academic future moves to the forefront as she contemplates applying to New York University.
• Her relationship with Min Ho deepens and complicates her plans, forcing her to prioritize between love and personal goals.
• Family and community issues — like financial instability and unexpected pregnancies — push Kitty into more responsible, empathetic roles.

Anna Cathcart on growing up with the role

Playing Kitty since her teens has tracked Anna Cathcart’s own maturation. The actress describes how the older cast and the original films offered guidance when she was just figuring out who she wanted to be. That off‑screen mentorship mirrored Kitty’s on‑screen journey: both the actor and the character learned to navigate adolescence while under public scrutiny.

Cathcart has talked about how meeting the original cast helped her feel anchored during uncertain years, and Season 3 lets her show a more nuanced performance — one that balances humor with vulnerability as Kitty grapples with bigger life questions.

How past choices set up this season’s stakes

Kitty’s earlier impulsiveness — from sending love notes to meddling in others’ affairs — fueled her move to Seoul and many of the romantic entanglements that followed. The show honors that history while making room for growth: the exuberant, love‑obsessed teen remains, but she’s now learning to act with intention.

Moments that signal a new Kitty

• Her initial plan to chase Min Ho on tour gives way to a more realistic focus on family and education.
• When a major miscommunication leads to a painful breakup, Kitty responds by reassessing her priorities rather than defining herself solely by heartbreak.
• She becomes a source of comfort for others — particularly a pregnant cousin — showing emotional maturity that didn’t exist in earlier seasons.

Friendships, family, and the weight of real problems

This season expands the canvas beyond teen drama clichés. Instead of leaning into sensationalized plotlines, XO, Kitty centers believable adolescent dilemmas: tuition decisions, family financial collapse, and complicated parental relationships. Those elements make the show’s quieter scenes hit harder because they feel lived‑in and relatable.

Notable developments:

1. Kitty’s sisterly bond with Lara Jean evolves; Lara Jean becomes a sounding board rather than the only problem‑fixer.
2. Kitty helps reunite estranged family members and supports friends through pregnancy scares, highlighting her emotional growth.
3. The cast’s age and the series’ tone stay true to teen experience, avoiding the absurd adult‑level stakes that plague some young‑adult shows.

Balancing whimsy and realism: what keeps the series fresh

The show preserves the rom‑com magic that fans love — the flirty tension, the stylized K‑drama beats, and those cinematic, swoonworthy moments between Kitty and Min Ho. But Season 3 also injects a dose of realism: not everything is a permanent plot line, and sometimes relationships are meaningful precisely because they’re temporary or transitional.

That approach lets the series celebrate romance without making it the sole axis of Kitty’s identity. She can want love and still pursue her own goals; the show treats these desires as compatible rather than mutually exclusive.

Kitty and Min Ho: where the finale leaves them

The season closes on a hopeful, kinetic note. After reconciling, Kitty and Min Ho make an impulsive, romantic sprint through Seoul that ends with them boarding a flight together — not to a permanent finish line, but to a new chapter in Portland. The moment reads like a true teen milestone: exhilarating, uncertain, and full of possibility.

Both actors acknowledge that what we see is a snapshot of young people figuring things out. The chemistry on screen suggests a deep connection, yet the series also reminds viewers that high‑school romances are often formative stages rather than final destinations.

Questions the ending raises

• Will Kitty’s acceptance to NYU change how she and Min Ho relate over time?
• Are Kitty and Min Ho’s plans a pause or a long‑term decision?
• How will Kitty’s evolving role in her family and community influence her next steps?

The season’s emotional throughline: choosing yourself without losing your heart

Ultimately, Season 3 positions Kitty at a crossroads. Her choices aren’t presented as betrayals of romance but as responsible steps toward building a life she owns. The series asks viewers to accept that growth can include both joyful romance and sober adult decisions.

As Kitty learns to live in the present rather than chase outcomes, the show gives her — and the audience — permission to embrace uncertainty. That willingness to let characters evolve naturally is what keeps XO, Kitty grounded and emotionally rewarding, even when the plot turns dramatic.

Season 3’s central takeaways for fans and new viewers

Whether you came for the cute moments with Min Ho or the connection to the wider To All the Boys world, Season 3 broadens the franchise’s emotional range. It keeps the fun beats but rewards viewers with deeper character work, showing how teen life can be both whimsical and serious at once.

• Expect romance and chemistry, but also real consequences and personal growth.
• Look for strong supporting scenes that highlight family dynamics and friendship as catalysts for change.
• If you’re invested in Kitty’s arc, this season delivers a version of her who is learning to choose herself while still cherishing love.

Season 3 of XO, Kitty is currently available to stream on Netflix.
