The fourth episode of XO, Kitty season 3 turns a routine school excursion into a compact emotional arc. What starts as a plan to visit a furniture museum quickly shifts when Kitty and her classmates persuade Professor Lee to take them to Lotte World in Seoul instead. The decision hinges on an old photograph Yuri shows Kitty — a snapshot of their mothers and the principal enjoying a French Revolution–themed ride — which Kitty uses to convince the class that the theme park holds historical and sentimental value. The result is a single-day microcosm of the season’s larger tensions: grades, future plans and teenage relationships.
The episode is notable for being filmed on location at the real Lotte World, an amusement complex that opened in 1989. The setting does more than provide a backdrop; it amplifies the story beats. Renting school uniforms, riding a massive roller coaster, navigating VIP queues and dealing with paparazzi all become devices to test the characters. In this episode, Kitty’s senior sunset anxieties, Min-ho’s career choices and Eunice’s public image converge in ways that are playful on the surface and consequential underneath.
From furniture museum to amusement park: how the switch reshapes the plot
The pivot from a calm educational outing to a theme park invasion is driven by Kitty’s imagination and the class’s collective push. Professor Lee initially prefers a visit to a furniture museum, but Kitty leverages the photo and a persuasive argument about educational value to flip the plan. The episode uses this turn to highlight Kitty’s initiative and to revisit Professor Lee’s past, showing how a simple photograph can open emotional doors. While the group scavenges for fun, the narrative also places midterm results front and center: Kitty’s fear about her grades is the engine of her unrest, and the park becomes the stage where she must decide whether her future will be ruled by tests or by friendships and lived moments.
Character flashpoints at Lotte World
Inside the park, multiple storylines play out in compressed form. Kitty and Min-ho share private moments — from a photo booth to a horror room — while Min-ho faces a looming career decision after a message about recording with Eunice. Their conversation teases the possibility of life plans that diverge: Min-ho’s potential move to NYU versus staying in Seoul. Eunice’s celebrity status creates immediate disruption when paparazzi capture her discomfort after a ride, securing the group VIP access but also public scrutiny. Meanwhile, secondary arcs — like Marius and Q’s reconciliation and Yuri’s money worries — receive short, meaningful beats that reflect the episode’s theme of transition.
Small moments that reveal big choices
Several compact scenes do the heavy lifting emotionally. Kitty refusing to check her exam score, then ultimately seeing that she passed, is framed as a victory over self-imposed pressure: the midterms no longer define her. Jiwon and Alex’s decision to rent school uniforms nods to real-life park customs and highlights the show’s attention to cultural detail. Eunice’s sudden pregnancy revelation at the episode’s close — and a private embrace with Min-ho seen from Kitty’s dorm window — raises stakes for future episodes, touching on trust, timing and the ripple effects of fame.
What the show left out — and why it matters
Although the episode showcases several attractions, it deliberately omits much of what the real Lotte World offers: the ice rink, parades, live shows and a folk history museum go unexplored by the narrative. That choice keeps the focus tight on relationships rather than on tourism. The series does nod to authenticity, though: the park’s size and role as part of the Lotte conglomerate are referenced, and the uniform-rental trend is acknowledged. By trimming the tourist checklist, the writers use the park as a concentrated crucible for character development rather than a travelogue.
Why this episode matters for the season
Episode 4 acts as a pressure cooker, compressing the season’s broader arcs into a single, eventful day. It resets priorities for Kitty, clarifies potential splits in future plans for Min-ho, and amplifies Eunice’s precarious celebrity narrative. The combination of exam anxiety, public exposure and intimate conversations ensures that the choices made on this field trip will echo through the rest of the season. The show balances humor and drama, using senior milestones and a familiar real-world location to explore how a single outing can alter trajectories and relationships.
