XO, Kitty Season 4 Explained: Why Fans Think Kitty Is Heading Back to Seoul for Graduation

LOS ANGELES — Just two weeks after the April 2nd premiere of XO, Kitty Season 3, the fandom is already deep into what comes next.

Kitty Song Covey and Min Ho essentially broke the internet by ditching Seoul for Portland in the finale, leaving every “KISS” scholarship student in the dust.

While Netflix is keeping its cards close to its chest regarding an official Season 4 renewal, the digital streets are talking. Stan Twitter has pivoted from shipping wars to full-blown detective work, trying to figure out how a rich kid from Seoul survives the rainy suburbs of Oregon.

The impact of this latest cliffhanger is massive for the To All the Boys universe. For the first time, we aren’t just looking at the drama in South Korea; we are watching a global collision of two very different worlds.

If the show returns, it won’t just be about romance. It will be about the ultimate culture shock for the guy who once thought a private jet was a standard mode of transportation. This moves the needle for the series, shifting it from a “study abroad” fantasy to a grounded “fish out of water” comedy.

Is Min Ho actually built for life in Portland, or is this romantic gesture a ticking time bomb?

It is a fair question to ask.

Moving across the world for a girl you just made things official with is a bold move, even for a guy with a bottomless bank account. But looking at the narrative breadcrumbs dropped throughout the eight-episode binge, the fans might have already cracked the code for Season 4.

Theory 1: The Oregon Culture Shock Arc

The most obvious theory involves Min Ho’s total lack of survival skills in a non-luxury environment.

Fans on Reddit are convinced that Season 4 will spend significant time showing Min Ho trying to adjust to Kitty’s world. We are talking about a guy who defines himself by high-society Seoul standards. Portland is the city of flannel, rain, and public transit.

The Richie-Rich Reality Check

Insiders have noted that the show thrives on contrast, and placing Min Ho in a Portland coffee shop is the ultimate “PR move” for his character development.

The theory suggests he will struggle with the simple stuff—like doing laundry or sharing a bathroom—which will test his and Kitty’s new relationship to the breaking point. It is a classic rom-com trope, but given Sang Heon Lee’s comedic timing, it is absolute gold.

Theory 2: The “Final Semester” Return to Seoul

Wait, did everyone forget Kitty hasn’t actually graduated? As per the official timeline, Kitty still has her final semester at the Korean Independent School of Seoul (KISS) to finish.

This has led to a widely accepted theory that the Portland trip is just a summer fling before reality hits.

One Last Semester at KISS

The theory suggests that the first half of Season 4 will see the couple returning to Seoul for their senior graduation.

This would allow the show to bring back fan-favorites like Q and Yuri for a proper send-off. It makes sense.

You can’t have a show called XO, Kitty that ends before the graduation caps are thrown. Plus, Kitty still has those deep ties to her mother’s past at KISS that feel like they need one final chapter.

Theory 3: The NYU Graduation Goal

According to clues dropped in Season 3, Kitty is eyeing a future in New York for college. These lines up perfectly with the rest of the Covey sisters’ trajectory. The “Big Apple” theory suggests that Season 4 will conclude with Kitty and Min Ho deciding on their college futures together.

Showrunner Valentina Garza mentioned that the team is taking a “wait and see” approach, but the narrative points toward a New York reunion.

With Lana Condor officially back in the mix as Lara Jean, the possibility of the Song Covey sisters all being in the same city for the first time since the original trilogy is a “chart-topper” idea for the finale.

As of now, we are all just waiting for that official “Green Light” from Netflix headquarters. But if these theories are any indication, Kitty’s story is far from over. Whether she is in Oregon, Seoul, or New York, the chaos is guaranteed to follow.
