How EXO Kai Turned a YouTube Variety Show Into a 103-Million-View Gen-Z Phenomenon

Some entertainers spend years searching for a second identity. EXO's Kai found his on a college campus. Since taking over as the new host of Changing Majors (전과자) in September 2025, the idol has turned a quirky YouTube concept — visiting university departments and experiencing their courses firsthand — into one of Korean streaming's most-watched variety properties. By the time the show's sixth season wrapped, it had accumulated 103.52 million cumulative views, a number that places it comfortably among the most successful idol-hosted web series in recent Korean entertainment history.

Season 8 premiered on March 26, 2026 — and it arrived with a revelation. After nearly 16 years of performing under the name "Kai," the EXO member disclosed on camera that he had only learned the true meaning behind his stage name by watching television. The admission drew an immediate surge of reactions from fans and media alike, but it also points to something larger: how K-pop's most established stars are finding unexpected depth, and unexpected connection, through the slow, sprawling format of long-form YouTube variety content.

A Show Built on Curiosity — and the Right Person to Host It

Changing Majors launched in 2022 under BTOB's Lee Chang-sub, whose five-season run established the show's core appeal: a celebrity who knows nothing about academic departments spending time actually learning them, with campus students as scene partners rather than props. The show released episodes every Thursday at 6 PM KST on ootb Studio's YouTube channel, a Kakao Entertainment subsidiary, and the format proved quietly durable. Lee Chang-sub left after Season 5 due to throat health concerns, and the production team faced a real question: who could sustain the chemistry?

EXO's Kai was announced as his successor on February 17, 2025. The logic of the casting was not immediately obvious. Kai's public persona is built on precision — he is widely considered one of the most technically skilled dancers in the Korean idol industry, known for controlled, exacting performances that leave little room for spontaneity. Variety television tends to reward something quite different. But Season 6's premiere at KAIST answered the skepticism quickly. Kai walked onto campus, noticed several facilities that shared his name, and announced: "I feel a connection with this school because of our similar names." Then he proceeded to find every possible location with "Kai" in the signage. The moment became a meme within days.

What Season 6 ultimately revealed was that Kai's precision extends to reading situations. His wit is dry, fast, and calibrated — not the broad performance of a traditional variety personality, but something more aligned with the understated humor that Gen-Z audiences identify with. When a Chemistry Department class left him visibly struggling, he turned to the camera and deadpanned: "I'm a hacker now, soon to be a doctor." The moment did not require a laugh track. It did not need one.

The 103 Million View Question: Why This Format Works Right Now

The numbers deserve scrutiny. 103.52 million cumulative views for a single season of a YouTube variety show — one with no broadcast network, no prime time slot, no talent competition hook — is not what conventional wisdom about idol content predicts. K-pop audiences are known for organized streaming campaigns and fandom-driven metrics that can distort picture. But the specific character of Changing Majors' viewership is harder to game: the show's campus settings attract university students and young adults who may not be core EXO fans, and its educational angle draws genuine curiosity engagement rather than pure loyalty streaming.

The production team cited real-world impact as evidence of the show's reach. After an early episode covered the dining hall situation at Yeonsung University, the university reportedly expanded its cafeteria menu from 2 available dishes to 40. That is the kind of downstream consequence that does not emerge from fan replay metrics — it emerges from actual viewers watching with actual attention. By May 2025, ENA began airing reruns, and by January 2026, the spin-off Jeongwating — a group dating format built around university students — had launched as a standalone series. Changing Majors had become a franchise.

What the show tapped into is a specific Gen-Z appetite: content that does not perform aspiration but reflects genuine engagement with unfamiliar environments. The variety landscape of the previous decade was built on idols navigating extreme physical challenges or manufactured social awkwardness. Changing Majors offers something quieter. It lets a famous person be genuinely uncertain, genuinely curious, and genuinely learning — in front of students who are the same age as the fans watching at home. The parasocial intimacy of that structure is not incidental. It is the product.

Season 8 and the Stage Name Reveal: What It Actually Means

The disclosure that generated the most immediate attention heading into Season 8 is easy to reduce to a headline: Kai found out what his own name means after 16 years. But the context of how that happened — watching television, not receiving a direct explanation from his company or his managers — is the part worth sitting with. Stage names in the K-pop industry are not always assigned with ceremony. They are often given early in a trainee's development, sometimes before the person carrying them is old enough to think critically about what they signify, and the mythology around them tends to build organically rather than through official disclosure.

For Kai to learn the meaning on-camera, in front of a university audience, rather than in some formal industry context, is characteristic of exactly what makes the show work. The campus environment lowers the guard. It creates situations that cannot be fully controlled. And it tends to produce the kind of genuine surprise — or genuine revelation — that polished promotional content carefully avoids. Season 8's premiere also revisited a rivalry dynamic: Suho, who served as a substitute host during a scheduling gap, returns to complete against Kai at Inha University of Technology's Business Secretary Department. The competition element adds structural tension to an episode that already had a ready emotional hook.

What this moment demonstrates is that Kai, now in his early thirties with a decade and a half of idol career behind him, is not using Changing Majors to introduce himself to a new audience. He is using it to reveal a different dimension of a self that his existing audience has been watching for years. The distance between who he appears to be in a choreographed performance and who he appears to be debating a student about chickens and eggs is the show's actual product. At 103 million views and counting, the audience has clearly found that distance interesting.

K-Pop's YouTube Turn: Changing Majors as a Blueprint

The success of Changing Majors under Kai sits within a broader shift in how K-pop interacts with long-form content. YouTube now drives discovery more consistently than Korean broadcast television for global K-pop audiences, and the industry has spent the last several years developing formats that can hold viewer attention across multiple episodes without the production infrastructure of a traditional network show. Changing Majors — produced by a Kakao subsidiary, distributed through YouTube, and picked up for cable reruns only after its digital success was established — represents one version of what that shift looks like in practice.

What distinguishes it from the wave of idol-fronted web series that have not achieved comparable traction is the structural patience of the format. A 30-minute show releasing weekly, building relationships with campus environments over an entire season, accumulates the kind of contextual depth that shorter content cannot replicate. By Season 8, Kai is not a guest on a university campus. He is a returning figure with an established dynamic — and the audience, now more than 100 million views into the relationship, has developed an investment that extends beyond any single episode. That depth of engagement, cultivated over time through consistent presence rather than spectacular event, may be the most replicable thing about the show's success story.
