The Identity Of The Girl In BTS’s New Video That ARMYs Name “The Coolest Girl Ever“

BTS have released countless music videos and various types of content throughout their career, from group projects to individual solo works. However, the number of times they have collaborated with female artists or female public figures remains relatively limited. Some of the few actresses who have appeared include Shin Se-kyung, Han So-hee, and IU. In addition, there have been special appearances such as members of ITZY during their trainee days, and more recently, legendary supermodel Soo Joo Park.

Every time BTS collaborate with these notable female figures, fans never hide their excitement and always show enthusiastic support. However, when it comes to the title of “the coolest girl ever” αѕѕociated with BTS collaborations, ARMY had never truly given it to anyone—until the appearance of the female figure in their latest short documentary, who instantly captured the fandom’s heart!

Specifically, BTS and BigHit Music have launched a YouTube Shorts series titled “KEEP SWIMMING with BTS,” aimed at conveying the value of perseverance. This project is a campaign built on the message “keep moving forward” from “SWIM,” the title track of their fifth studio album “ARIRANG.” In an era where groundbreaking achievements are often prioritized, this campaign instead reflects on the weight of effort and the “steady rhythm of everyday life” behind results, rather than focusing solely on the results themselves.

The videos revisit moments when individuals “keep swimming” in their own journeys, delivering the message that simply not stopping is already a meaningful form of progress. Using the life stories of masters representing different fields to express the song’s message is a fresh and distinctive approach. In its first two episodes, the series featured renowned figures in their respective industries: director Park Chan-wook—the visionary who brought кσяєαn cinema to the global stage—and designer Nora Noh, the first fashion designer of кσяєα.

Meanwhile, in the latest episode released on April 10, the main character is υиєχρє¢тє∂ly a young woman with a beautiful appearance yet an incredibly strong presence. From the very first moments, she appears with a snowboard, performing sкιℓℓful runs in a halfpipe, instantly captivating viewers. Shortly after, her identity is revealed: Choi Ga On—a snowboarder who has won the World Cup halfpipe event four times.

Notably, this past February, she achieved a remarkable feat by defeating her own idol, Chloe Kim—a two-time Olympic champion—to win the gold medal at the Milano Cortina 2026 Winter Olympics. This victory was not only a personal milestone but also a historic achievement, as she became the first South кσяєαn female athlete to win a medal in snow sports.

What makes Ga On’s story even more extraordinary is that this achievement came shortly after her recovery from a serious injury—a knee injury that had prevented her from competing for several years. In the documentary, she candidly shared her difficult journey back to Olympic preparation: “Both of my knees hurt so badly that I couldn’t move at all. But I started by trying to move my toes, thinking ‘Please… just once… please move…’”

Moreover, when asked what keeps her going, Ga On revealed a level of maturity far beyond her 17 years: “Lately, I’ve been thinking since I’m a senior in high school. No one lives without hardships. So I tell myself ‘This is soмєтнing everyone goes through’. Because I love snowboarding so much, even when I’m injured or going through tough times. As long as I can ride again, I can get through it.”

She also demonstrated admirable determination by stating: “I’m aiming for the Olympics in four years and for now, my goal is simple—to stay healthy and make it to the next Olympics.”

At this point, it becomes clear why ARMY have been showering this young female figure with overwhelming praise. Beyond her beauty and talent, fans are deeply impressed by Ga On’s resilience, optimism, and maturity at such a young age. She truly embo∂ιєs the title of “the coolest girl ever”—a genuinely admirable fιgнтer.

On social media, videos of the snowboarder are being widely shared, accompanied by countless glowing compliments:
