Netflix’s XO, Kitty has always been full of surprises, but nothing could have prepared fans for the jaw-dropping twist rumored to be coming in Season 3. Just as Kitty and Minho’s undeniable chemistry was starting to blossom, shocking speculation suggests their romance might be forbidden—because they could be secretly related!

Could this be the most unexpected plot twist in the To All the Boys universe? And if it’s true, what does it mean for Kitty’s love life moving forward? Here’s everything we know about the XO, Kitty Season 3 bombshell that has fans spiraling!

Kitty & Minho’s Growing Chemistry – But at What Cost?

Season 2 of XO, Kitty left fans on the edge of their seats as the romance between Kitty Song Covey (played by Anna Cathcart) and Minho (Sang Heon Lee) seemed to finally gain momentum. After years of playful banter and undeniable tension, it felt like the perfect setup for a fan-favorite slow-burn romance in Season 3.

But just when things were getting good, a forbidden love twist might throw everything into chaos. According to rumors circulating online, new revelations in Season 3 could suggest that Kitty and Minho are actually long-lost cousins—a shocking secret that could derail their budding romance before it even begins!

How Could This Be Possible? A Deep Dive into the Theory

While it sounds crazy at first, there are a few compelling clues that make this theory hard to ignore:

1. Kitty’s Korean Roots & Unanswered Family Questions

Throughout the series, Kitty has been on a journey to learn more about her late mother’s past in Korea. She’s discovered family secrets before—so what if there’s one more shocking revelation waiting to be uncovered?

Some fan theories suggest that Kitty’s biological family in Korea might be larger than she ever imagined. What if her mother had long-lost relatives she never knew about… and one of them happens to be Minho’s family?

2. Minho’s Mysterious Family Background

Unlike other characters, we’ve learned very little about Minho’s family history. He’s wealthy, charming, and has an air of mystery about him. Could his parents be hiding a connection to Kitty’s Korean lineage?

If Minho’s mother or father turns out to be a distant relative of Kitty’s mother, that could explain why this bombshell is only now coming to light in Season 3.

3. The Show Loves Unexpected Twists

If there’s one thing XO, Kitty does well, it’s throwing unexpected curveballs at fans. From love triangles to shocking betrayals, the series thrives on jaw-dropping moments. A long-lost family revelation would be exactly the kind of high-stakes drama the show loves to introduce.

If Kitty & Minho Are Related, What Happens Next?

If this theory turns out to be true, it could change everything. Here’s what it might mean for XO, Kitty moving forward:

1. A Heartbreaking End to Their Romance

If Kitty and Minho find out they’re family, their romantic storyline would have to come to an abrupt (and devastating) halt. After all, XO, Kitty may love drama, but it’s not that kind of show! Fans hoping for a Kitty-Minho love story would be crushed.

2. A Shift in Kitty’s Love Interests

With Minho out of the picture romantically, Kitty might have to redirect her feelings elsewhere. Could this mean a rekindling of her relationship with Dae? Or perhaps a completely new love interest will be introduced in Season 3?

3. Minho’s Emotional Fallout

Minho has always played the role of the confident, flirtatious heartthrob, but this revelation could shake him to his core. How will he handle the news? Will he push Kitty away entirely, or will they remain close as family despite the awkward truth?

What Do the Cast & Creators Say?

While Netflix has remained tight-lipped about Season 3 details, some cryptic hints from the XO, Kitty cast have fueled speculation.

Sang Heon Lee (Minho) teased in a recent interview that Season 3 would be “unexpected” and “deeply emotional.” Could this be a hint at the shocking family twist?
Anna Cathcart (Kitty) also mentioned that her character will “face some really tough moments next season”—which could point to a devastating revelation about her love life.
Series creator Jenny Han has always loved shocking her fans with major twists. If this cousin bombshell is real, it would fit right in with her storytelling style.

Is This Just a Wild Theory—or Could It Actually Be True?

At this point, nothing is confirmed, but the theory is gaining traction fast. Some fans believe it’s simply a case of overanalyzing small clues, while others are convinced that Netflix has been planting the seeds for this revelation all along.

No matter what happens, one thing is certain: XO, Kitty Season 3 is shaping up to be the most dramatic yet. Whether or not the cousin theory turns out to be true, fans are in for major surprises, shocking heartbreaks, and possibly a brand-new love story for Kitty.
