With XO, Kitty Season 3 still fresh on Netflix (premiered April 2, 2026), anticipation for a potential Season 4 is already gaining momentum. The charming To All the Boys I’ve Loved Before spinoff delivered strong viewership in its opening week, hitting #1 on the Global English TV list with 55.9 million hours viewed. Fans are eager for the next installment to take Kitty Song Covey (Anna Cathcart) beyond senior-year romance and into more profound self-discovery—specifically, a deeper exploration of her late mother Eve Song’s past, family secrets, and Korean heritage that have quietly shaped Kitty’s journey since Season 1.

Kitty’s Ongoing Connection to Her Mother’s Legacy

From the very beginning, Kitty’s decision to attend the Korean Independent School of Seoul (KISS) was driven by her desire to understand her Korean-American roots through her mother Eve, who studied there years earlier. Across previous seasons, Kitty uncovered family rifts, old letters between Eve and Simon, a near-reconciliation trip that never happened due to Eve’s tragic death (a slip and head injury when Kitty was young), and connections to Principal Lim (Eve’s former roommate and best friend).

Season 3 advanced Kitty’s emotional growth during her senior year, including reconciling with Min Ho (Sang Heon Lee) and heading to Portland for winter break with him meeting her family. Yet the show has left room for more layers: unresolved family history on her mother’s side, the cultural identity struggles of being biracial, and how Eve’s unfulfilled plans echo in Kitty’s own big decisions about college (NYU early decision), romance, and where she belongs.

Fans hope Season 4 dives even deeper—perhaps through flashbacks, more interactions with Korean relatives, or Kitty discovering additional artifacts, letters, or stories from Eve’s time at KISS and her life in the U.S. This could tie into Kitty’s “whole new chapter,” forcing her to confront how her mother’s past influences her future choices amid post-high-school transitions.

Release Date Rumors and Renewal Outlook

Netflix has not officially renewed XO, Kitty for Season 4 as of mid-April 2026, but the pattern and Season 3’s solid performance point toward a likely greenlight. Previous gaps show Season 2 arrived in January 2025 and Season 3 roughly 15 months later in April 2026. If renewed soon (potentially by May, following Netflix’s typical timeline for strong performers), filming could begin in late 2026, with a Season 4 release targeted for early-to-mid 2027—possibly spring or summer.

Some reports suggest early development discussions are underway, with the story potentially expanding beyond KISS as characters face graduation, college, and real-world challenges. Showrunner Valentina Garza has teased that Season 3 closes one chapter while opening another, with “many more relationship milestones” ahead for Kitty and Min Ho. Anna Cathcart has called the couple potential “end game” in interviews, while expressing excitement about exploring Min Ho in Portland and Kitty’s family dynamics on the iconic Covey couch.

Whether Season 4 serves as a final wrap-up for senior year or launches the group into early adulthood, the flexibility of this original series (not bound by a fixed book timeline) allows creators to lean into meaningful arcs like Kitty’s heritage exploration.

What a Deeper Mother’s Past Arc Could Look Like

Viewers speculate Season 4 could open after the Portland trip, with Kitty returning to Seoul for her final semester only to encounter new revelations. Possibilities include:

Kitty visiting more extended family or uncovering additional letters/diaries that reveal Eve’s dreams, regrets, or unshared stories from her KISS days.
Tying Eve’s history more explicitly to Kitty’s identity crisis—balancing her American life, potential NYU move, and Korean connections.
Emotional moments where Kitty shares discoveries with Min Ho or the friend group, strengthening bonds while highlighting themes of loss, reconciliation, and cultural belonging.

This focus would enrich Kitty’s coming-of-age story, building on her biracial experience and matchmaking optimism. It also aligns with the show’s strengths: heartfelt cultural representation, diverse friendships, and lighthearted yet meaningful drama.

The core cast is expected to return, including Sang Heon Lee as Min Ho, Choi Min-yeong as Dae, Gia Kim as Yuri, Anthony Keyvan as Q, and Regan Aliyah as Juliana. Cameos from the To All the Boys universe (Lana Condor as Lara Jean or John Corbett as Kitty’s dad) could add warmth during family scenes. New characters might appear to introduce fresh conflicts, but the heart remains the ensemble navigating change together.

Why Fans Are Rooting for This Direction

XO, Kitty stands out for blending rom-com fun with authentic explorations of identity, first love, queer representation, and cross-cultural experiences. Kitty’s journey—from wide-eyed newcomer chasing her mother’s footsteps to a young woman embracing uncertainty—resonates because it feels genuine. A deeper dive into Eve’s past would give emotional weight to Kitty’s decisions about the future: long-distance with Min Ho, college paths, and what “home” truly means.

As discussions heat up on fan pages, Reddit, and social media, the consensus is clear: Season 4 has strong potential to deliver a satisfying, heartfelt conclusion or open exciting new doors. Netflix’s track record with successful teen originals, combined with Season 3’s momentum, makes renewal feel probable.

In the meantime, rewatching the series offers plenty of “XO” moments and clues about Eve’s life. Here’s hoping the next chapter brings Kitty closer to understanding her mother while stepping confidently into her own story—full of kisses, chaos, growth, and discovery.
