Kim Sejeong’s 2026 fan concert ‘열 번째 편지 (Tenth Letter)’ is finally coming to life in Seoul, and fans are already tracking every hint they can get. On January 10, short rehearsal clips and links shared via X (Twitter) and YouTube began circulating in fan communities, giving a brief but powerful glimpse of the show that will open her global fan-con tour.
These rehearsal posts, highlighted on Korean community site TheQoo, arrived just as excitement was peaking for the Seoul dates, which mark the start of Kim Sejeong’s officially announced 2026 global fan concert tour ‘열 번째 편지 / Tenth Letter’.
Kim Sejeong rehearsal clips spark fan reactions
According to fan-community posts on January 10, users shared:
- Short video clips from the rehearsal
- Direct links to X (Twitter) posts
- YouTube Shorts links capturing moments from the practice stage
Verified: Fan posts on TheQoo compiled X and YouTube links showing Kim Sejeong rehearsing for the 2026 KIM SEJEONG FAN CONCERT ‘열 번째 편지’ in Seoul, posted on January 10.
While the clips themselves are short and informal, they function much like an organic teaser before a major K-POP event. In the current industry landscape, rehearsal snippets often act as a soft preview of:
- Stage atmosphere and live-band or track-based setup
- Possible arrangement style or performance mood
- The artist’s condition and presence right before showtime
Based on currently available information, no detailed setlist, outfit concept, or stage effects have been officially revealed through these rehearsal leaks. It appears that only partial angles and brief moments were captured, which is typical when fans share content taken from outside or around official practice spaces.
‘열 번째 편지’ in Seoul: start of a global fan-con tour
What makes these rehearsal clips more meaningful is the timing. The Seoul fan concert is not just a one-off show; it is the starting point of Kim Sejeong’s global fan-con tour that had already been announced through official channels.
In general within the K-POP industry, when:
- A tour is framed around a symbolic title like “Tenth Letter”,
- The artist is marking a major milestone such as a debut anniversary,
the opening city—here, Seoul—usually sets the emotional and production tone for the rest of the tour. Fans often pay close attention to:
- How the first city’s staging might be adapted or scaled for overseas stops
- Whether fan events, talk segments, or VCRs follow a consistent structure
- How the narrative of the concert (here, the “letter” concept) is expressed on stage
So far, only the broad tour framework is publicly known: Seoul as the kick-off and multiple cities to follow as part of the 2026 ‘Tenth Letter’ fan-con series. Specifics like additional countries, venue capacities, and detailed time slots for later stops are typically released city by city via local promoters and official platforms.
TheQoo threads capture real-time fan excitement
On TheQoo, a popular Korean online community, the rehearsal-related post for “2026 KIM SEJEONG FAN CONCERT <열 번째 편지> TO SEOUL REHEARSAL” gathered attention as users clicked through the embedded X and YouTube links. The thread itself mainly serves as a curation hub:
- One place where fans can quickly find scattered SNS links
- A space for short comments and reactions

Verified: TheQoo’s Kim Sejeong category featured a post titled “2026 KIM SEJEONG FAN CONCERT <열 번째 편지> TO SEOUL REHEARSAL”, including X and YouTube Shorts links and timestamped January 10.
As is common in K-POP fandom culture, these community threads function almost like real-time news tickers, updating faster than formal media:
- Fans spot new posts on X or YouTube

- Other users react, analyze, and speculate about performance details
However, based on what is currently visible, there are no official spoilers about the full concert structure in these posts—only glimpses that suggest active on-site preparation.
Industry context: rehearsal leaks as organic promotion
From a K-POP journalist’s perspective, what is happening around Kim Sejeong’s ‘열 번째 편지’ rehearsals fits a broader industry pattern:
- Rehearsal or sound-check content often circulates first on fan-run SNS accounts.
- Communities like TheQoo, DC Inside, or global platforms like Reddit and Twitter/X amplify those links.
- Without revealing full songs or choreography, these clips still build anticipation and search traffic ahead of opening night.
For an artist like Kim Sejeong, who has built a career across both dramas and music, a fan concert tour branded around a “letter” concept naturally invites expectations of:
- Storytelling segments or ment portions reflecting on her years with fans
- A setlist that typically spans drama OSTs, solo releases, and fan favorites
That said, none of these elements have been confirmed for the Seoul show through the rehearsal leaks themselves. They remain educated guesses based on standard K-POP fan-con structures.
