BTS star Jimin finally made his TikTok debut on September 28, 2026 — and the internet was already waiting for him. Before he had posted a single video, more than five million people had followed his personal account. When the first clip finally dropped, a sunset dance performance to "Be Mine" from his second solo album MUSE, it collected over 15 million views within about two days, according to KStarTrend. For one of K-pop's most-followed dancers, it turns out the platform was just the last piece of the puzzle.

Jimin chose performance over introduction. Rather than a casual greeting or a selfie video, his first upload was pure dance: an outdoor clip, filmed against a warm sunset with a coastal backdrop, showing newly revealed choreography for a track that fans had waited years to see performed in full. "Be Mine" was released in 2024, but Jimin had never presented a complete official dance for it until now, reported by allkpop. In one upload, he delivered two long-awaited moments at once: his first personal TikTok post and the first real look at a complete "Be Mine" performance.

The response was instant. The video hit one million likes in roughly two hours, passed ten million views with 4.55 million likes within about 16 hours, and by midnight on September 30 it had grown to more than 15 million views and six million likes. It also reportedly reached number one on TikTok's U.S. trends. Dance covers inspired by his choreography started appearing less than an hour after the upload, and TikTok Korea highlighted the post on its official account.

The Jimin TikTok debut by the numbers

The strangest part of the story is what happened before anything was posted. Jimin's personal account, under the handle @jimin, surfaced around late August 2026. Fans discovered it and started following even though it contained no public videos. By September 14, the empty account had passed five million followers, as fan accounts tracked in real time. The account kept growing after that, reaching about 5.3 million followers without a single upload, then adding more than a million in the day after the first video went live, pushing the total past 6.5 million.

Those figures are remarkable even by K-pop standards. Following an account with zero content is an act of pure anticipation — there was nothing to watch, like, or share. The crowd was essentially pre-assembling for an event nobody had confirmed was coming. That the gamble paid off with a dance performance, rather than a lifestyle update, only reinforced why Jimin's followers were waiting in the first place.

Why the debut hit differently

Jimin's choice of first post was strategic in the way only great performers manage. The #thisisjimin hashtag attached to the video connects back to his earlier dance-focused content, framing the debut as a continuation of what fans already know him for. The outdoor setting mattered too: without a produced stage, the choreography itself stayed the center of attention, giving the performance an intimate feel that a studio version would not have had.

Fan reaction centered on the choreography more than the platform milestone. Comments across TikTok and other social platforms kept returning to the same point: they finally got to see the "Be Mine" dance. "Finally Jimin posted a video" and "We finally get to see the Be Mine choreography" were typical responses, according to allkpop's coverage of the debut. In other words, the Jimin TikTok debut played to the platform's strengths — a loopable performance rather than a talking head — which is exactly the kind of content TikTok's recommendation system rewards.

Jimin is now the fourth member of BTS to establish a personal TikTok presence, following Jung Kook, j-hope, and V, who opened his account in March 2026. The rest of the group continues to maintain its wider social media presence, but the member-by-member migration to personal TikTok accounts signals how central short-form video has become to K-pop's direct connection with fans — even for artists who can summon a stadium-sized audience without trying.

What the numbers can and cannot tell us

A caveat belongs here. View and follower counts are platform-reported, and TikTok's metrics count autoplay replays and curiosity clicks alongside genuine fandom. Some of those millions were surely ARMY members who would follow Jimin anywhere; others were simply riding a trend wave to number one in the U.S. The debut's real signal is not any single tally but the sequence: an empty account drew a crowd, the first post outperformed what most established creators manage in months, and the choreography spawned imitations within the hour.

For readers watching this unfold, the takeaway is less about one star and more about how fandom works now. Discovery happens on fan-run accounts and aggregation posts; the official content arrives last, and when it does, it has to be worth the wait. Jimin bet that dance — his defining skill — was worth it. The view count suggests he was right.
