Beyond Music to a “Universe”: The Lasting Legacy of BTS’s ‘The Most Beautiful Moment in Life’

A blood-stained boy, sunlight filtering through a window, and the sound of birds create a jarring contrast. Tears streaming down his face, he washes his blood-stained hands as if trying to erase a terrifying memory. For him, youth wasn’t about beauty, but “anxiety.” He desperately searches for his “hyung.” As his savior and six other boys gather, the story begins. The “most brilliant time,” a youth “too beautiful to be scary,” was incredibly unstable. These broken youths cling to one another—a bond of solidarity, constantly trying to save each other even if salvation seems impossible. ‘The Most Beautiful Moment in Life on Stage: Prologue’ marks the starting point of the BTS narrative.

In K-pop history, a “universe” is more than just a concept. It’s a platform that keeps fandoms engaged, an “independent IP (Intellectual Property)” that extends an artist’s longevity, and a “sustainable asset” coveted by the global entertainment industry. At the heart of this massive shift was the “BTS Universe,” or “BU.”

BTS’s 2015 ‘The Most Beautiful Moment in Life’ (HYYH) served as a textbook for K-pop universes and the blueprint for HYBE’s story IP strategy. The ‘BTS Universe (BU)’ established the standard for “transmedia storytelling” by blending the artists’ musical messages with a “virtual narrative” and expanding them into other IPs like webtoons and novels. This journey has now expanded through their 5th studio album ‘ARIRANG,’ building a new story for the ‘BTS 2.0’ era.

In their early ‘School Trilogy,’ BTS were typical teenage boys resisting social oppression. However, starting in 2015, they began a new story. The music video for ‘I Need U,’ the title track of ‘The Most Beautiful Moment in Life pt.1,’ marked the beginning of their “character reboot.”

“Burning flowers, wet sneakers, train station platforms, and repeating cycles of falling and death.”

The music video left K-pop fans at the time with a strange sensation. The explanations were cryptic, and the story was fragmented. Scenes seemed to connect only to break apart, and the characters’ emotions were never clearly defined. Fans began “decoding” the music video, co-creating the story together.

The music video features seven virtual characters based on the members’ real names. Through them, the anxiety, pain, and solidarity hidden behind the “universal theme” of youth were dramatically unfolded.

The “time loop” setting centered around Kim Seokjin (Jin) was the key device that birthed a “participatory interpretation culture” among fans. Fandoms, who previously passively accepted the universes set by K-pop agencies, became “co-narrative creators” through the BU. As a result, fans began to “live” within the artist’s universe. They stopped being mere consumers of music and started acting as IP creators themselves.

The ‘HYYH’ narrative was later published as the Naver webtoon ‘The Most Beautiful Moment in Life Pt.0’ and the novel ‘The Most Beautiful Moment in Life: The Note’ in 2019. Detailed stories and characters featuring the members deepened the fandom’s immersion. The strength of this solid “original text” gave the fandom a powerful self-sufficiency, allowing them to consume and reproduce the narrative even during the artists’ hiatuses.

Ten years later, the BTS universe expanded from the acceptance of wounds in ‘LOVE YOURSELF’ to the exploration of the human inner self in ‘MAP OF THE SOUL.’ The 2026 narrative finally moves beyond individual youth to a layer of collective memory: the 5th studio album ‘ARIRANG,’ released last March.

The “shaking youth” who started as “dirt spoon idols” have grown into a completely different self over a decade. Now at the center of the global music market, the group has evolved into a new dimension that combines ethnic identity with global universality.

The core drive of the album comes from a historical true story: in 1896, Korean youths recorded ‘Arirang’ for the first time at Howard University in Washington D.C., USA.

Seven young men—including Ahn Jeong-sik, Lee Hee-cheol, and Son Young-deok—who fled to the U.S. to escape Japanese surveillance, left their voices on wax cylinders in a strange foreign land. This event, later known as “The Howard Seven,” fatefully overlaps with the seven members of BTS across 130 years.

HYBE presented this historical research through a one-minute animated teaser. By depicting the youths of 1896 gathered around a phonograph transitioning into BTS at their 2013 debut, they symbolized the “cultural resilience” of Koreans. The survival narrative of the past diaspora and the present “Korean” BTS, who have become global pop stars, overlap in a single scene.

The “survival memories” of those who had to live as outsiders resonate with the history of BTS, who were born in Korea and pulled “K-pop”—once a peripheral content—into the center of the world. The ‘Arirang narrative’ is both a search for BTS’s roots and an expansion of their universe. In the album, BTS refer to themselves as “Aliens,” redefining the experience of being othered by Western standards as something special.

While ‘HYYH’ dealt with the anxiety and loss of individual youth, ‘ARIRANG’ expands those emotions to the level of collective memory and diaspora. The BTS universe evolves beyond a youth narrative into a modern myth dealing with migration, survival, otherness, and recovery.

Immediately after its release, the ‘ARIRANG’ album swept the #1 spot on Apple Music charts in 115 countries. The title track ‘Swim (SWIM)’ reached #1 on the Billboard Hot 100.

Prior to the album’s release, BTS launched a universal campaign asking, “What is your love song?” leading fans into the universe in a familiar way.

In reality, the traditional K-pop consumption cycle lacked sustainability. An industry insider noted, “Consumption usually explodes during a comeback, but there’s a tendency for shallow fanbases to drift away during hiatuses. To increase fan loyalty and dwell time, there is a growing need for IP diversification.”

A universe expanded into a story IP, like that of BTS, increases the time fans spend engaged. Fandoms who laugh and cry with the artist’s universe maintain high loyalty, staying for the story rather than just a few hit songs.

K-pop is no longer just a music industry. It is seeking expansion by approaching a “narrative industry” that moves around characters and universes, similar to Marvel, Star Wars, or Harry Potter.

An industry official stated, “Once a solid universe is created, content expansion into webtoons, animation, and games becomes infinite. This leads to the consumption of individual merchandise through each piece of content, creating a virtuous cycle for the IP.”
