The Mystery Guest Clue
During a September Weverse live stream, LE SSERAFIM members dropped a tantalizing hint: “There’s going to be a special guest for Tokyo Dome. Oh, that’s right, there’s something we’re working hard on.” The vague statement left fans buzzing with speculation—until the j-hope collaboration teaser dropped.
The timing couldn’t be more perfect. The “SPAGHETTI” single featuring j-hope releases October 24, just three weeks before the Tokyo Dome encore concerts. For context, Tokyo Dome represents one of Asia’s most prestigious venues, seating 55,000 fans. Landing a BTS member as your special guest at such a milestone? That’s K-pop royalty confirming your arrival.
Why Fans Are Convinced It’s J-Hope
The Collaboration Connection: J-hope appears in LE SSERAFIM’s “The Kick” teaser video, showcasing dynamic choreography under strobe lights before both artists perform “Eat it up” together. This marks his first collaboration with a K-pop girl group—a historic moment that deserves a live debut.
Previous Musical Partnership: This isn’t their first rodeo. LE SSERAFIM member Huh Yunjin featured on “I Don’t Know” from j-hope’s “Hope on the Street Vol. 1” album earlier in 2025, establishing creative chemistry between the artists.
Songwriter Credit: J-hope is credited as a songwriter on “SPAGHETTI,” suggesting deep involvement beyond a casual feature. Artists typically promote songs they’ve genuinely invested in, making a Tokyo Dome performance logical.
HYBE Family Support: Both acts fall under HYBE Labels, Korea’s entertainment powerhouse behind BTS, LE SSERAFIM, NewJeans, and more. Senior artists supporting junior groups through surprise appearances is HYBE tradition.
Fan Reactions Explode Online
Social media erupted with speculation. “COULD IT BE J-HOPE??” became the rallying cry across X (formerly Twitter), with fans oscillating between cautious optimism and unbridled excitement.
One fan tweeted: “DON’T GET MY HOPES UP I CAN’T TAKE THIS 😭😭😭” capturing the collective anxiety of thousands hoping for confirmation. Another declared: “I WOULD GENUINELY DIE” at the prospect of witnessing this collaboration live.
The desperation is palpable. International fans are already regretting not securing Tokyo Dome tickets, while lucky attendees are manifesting a j-hope appearance with every fiber of their being. For more K-pop concert experiences and guides, check out our live performance coverage.
LE SSERAFIM’s Milestone Moment
The “EASY CRAZY HOT” world tour concluded after 27 performances across 18 cities supporting their three-part mini-album project: EASY (2024), CRAZY (2024), and HOT (2025). The tour launched at Incheon’s Inspire Arena in April and showcased the quintet’s explosive growth.
These Tokyo Dome encore concerts represent career-defining milestones. The venue has hosted K-pop legends like BTS, BLACKPINK, and TWICE—LE SSERAFIM joining those ranks confirms their elite status. Adding j-hope would transform these shows from victory laps into historic events.
The group’s recent achievements include their “HOT” EP debuting at No. 9 on the Billboard 200, proving their international appeal extends beyond Asia. Explore their complete discography journey on our LE SSERAFIM profile page.
What This Means for Both Fandoms
ARMY (BTS fans) and FEARNOT (LE SSERAFIM fans) rarely unite with such singular focus. This collaboration bridges both communities, creating anticipation rarely seen outside comeback seasons. If j-hope appears at Tokyo Dome, expect viral fancams, trending hashtags worldwide, and memories that define 2025’s K-pop landscape.
The strategic brilliance is undeniable. Release the collaboration three weeks before the concerts, build hype through mystery, then deliver the payoff with a surprise performance. It’s K-pop marketing at its finest.
