In a delightful cross-group interaction that has sent the K-pop fandom into a frenzy, BTS leader RM recently shared his own unique rendition of LE SSERAFIM’s latest dance challenge.
On April 27, 2026, RM uploaded a lighthearted video to his personal social media account, participating in the trending challenge for LE SSERAFIM’s new title track, “CELEBRATION.”
Known for his intellectual persona and deep artistic reflections, RM surprised fans by leaning into a purely comedic and “playful” vibe.
The video features the superstar wearing a plush hat inspired by the Pokémon Psyduck, a choice that perfectly encapsulated the whimsical energy of the post.
The highlight of the video was RM’s creative use of everyday props to enhance the choreography. Instead of a traditional dance cover, he incorporated an iced coffee cup and a serving tray into his movements, treating them as part of a rhythmic routine.
This “everyday life” approach to the challenge resonated deeply with fans, who appreciated seeing a more relaxed and humorous side of the global icon.
The interaction didn’t stop with RM; fellow BTS member j-hope was quick to join the fun, leaving a laughing emoji in the comments.
This brief but public display of their “strong bond” and support for their junior labelmates has been hailed as a highlight of the current promotional season.
The Success of LE SSERAFIM’s “PUREFLOW” Era
The track at the center of the challenge, “CELEBRATION,” is the lead single from LE SSERAFIM’s second full-length album, “PUREFLOW,” which was released on April 24, 2026.
The album has already proven to be a massive success, with its “viral” choreography sparking participation from numerous artists across the industry.
RM’s endorsement is particularly significant, as it brings the song to the attention of the massive global ARMY fanbase.
The synergy between HYBE labels remains a powerful force in the industry, with senior artists frequently using their platforms to support new releases.
LE SSERAFIM has been praised for the “PUREFLOW” era’s sonic evolution, which blends their signature high-energy dance style with a more refined, melodic sound.
The “CELEBRATION” challenge, in particular, was designed to be inclusive and fun, encouraging fans and fellow idols alike to put their own spin on the moves.
By opting for a Psyduck-themed, coffee-fueled performance, RM perfectly captured the spirit of the campaign- making music a shared source of joy rather than just a performance.
The video quickly garnered millions of likes and shares, with “RM_Psyduck” trending shortly after the upload.
A Legacy of Humility and Support
RM’s decision to participate in the challenge with such a “humorous twist” underscores his reputation as a humble and supportive leader.
Despite his status as one of the most successful musicians in the world, he continues to engage with the K-pop community in ways that are accessible and genuine.
His participation serves as a “bridge” between the different generations of artists under the HYBE umbrella, fostering a sense of unity and shared success.
Industry observers have noted that these types of organic interactions are often more effective for promotion than traditional advertising, as they feel like a “gift” to the fans.
As LE SSERAFIM continues their promotions for “PUREFLOW,” the momentum from RM’s video is likely to carry the song even further up the charts.
The group is currently preparing for their own world tour, and the visibility provided by senior icons like RM provides an invaluable boost.
For fans, the message is clear: even in a high-pressure industry, there is always room for a bit of playfulness and a Psyduck hat.
As noted by the staff at allkpop, the video was a welcome moment of levity:
“RM appears wearing a hat inspired by Psyduck… adding to the lighthearted vibe.”
Through this small gesture, RM once again proved that the best way to celebrate music is to simply have fun with it.
