fromis_9's Lee Chaeyoung Stuns Lee Mujin Service With Four Flawless Live Covers

fromis_9's Lee Chaeyoung brought the kind of live vocal performance to Lee Mujin Service that turns casual viewers into dedicated fans. In Episode 225 of the long-running KBS Kpop YouTube series, the 25-year-old idol moved through four songs with the confidence and control that only comes from genuinely loving what you are performing — and having the skill to back it up.

Lee Mujin Service, which airs on the KBS Kpop YouTube channel, has built its reputation on one thing above everything else: no studio tricks, no pre-recorded backing vocals, no safety net. The show strips performance down to its fundamentals — a stage, a microphone, and a musician who either delivers or doesn't. The guests who appear on the show know exactly what they're signing up for, and Lee Chaeyoung's willingness to take on four songs in a single session signals a level of confidence in her live abilities that the performance fully justified.

The Setlist and What It Reveals

Lee Chaeyoung opened with "Vitamin ME" before moving into the covers that would define the episode. Her rendition of Baek Yerin's "Bye Bye My Blue" showed her ability to inhabit the emotional architecture of someone else's song without losing herself in it — she brought the warmth and vulnerability the original demands while adding her own phrasing and emphasis.

The most technically demanding moment came with Taeyeon's "U R." The SM Entertainment idol is one of K-pop's most respected vocalists, and choosing to cover her work on a live-only platform is exactly the kind of choice that reveals where an artist truly stands. Lee Chaeyoung navigated the song with clarity and range, treating it as a conversation with the source material rather than a straightforward imitation.

The session closed with Choi Seong-won's "제주도의 푸른 밤 (The Blue Night of Jeju Island)" — a classic Korean pop song whose quiet emotional resonance requires a performer to trust the space in a song rather than filling it with excess. The choice to end there felt deliberate, almost like a statement about restraint and range existing within the same performance.

Lee Chaeyoung's Place Within fromis_9

fromis_9 is a nine-member girl group known for their consistent energy and warm relationship with their fanbase. The group has maintained a high level of activity through 2026, including a performance at K-PULSE Hanoi in Vietnam in June — an event that brought them in front of an international crowd at one of the year's significant K-culture export events. Lee Chaeyoung has also been active in brand partnerships, appearing in campaigns for Longchamp's 2026 Summer collection alongside fellow member Baek Jiheon at a Seoul event earlier this year.

Within the group, her solo appearance on Lee Mujin Service is a meaningful showcase moment. The show's format demands individual accountability in a way that group stages don't, and it's the kind of appearance that can shift how both industry insiders and fans perceive a member. For Lee Chaeyoung, Episode 225 becomes part of her own story as an artist, separate from the fromis_9 catalog but clearly shaped by it.

Her July brand ranking figures reflect this growing individual profile. In the July 2026 female idol individual brand rankings, she placed among the top tier — a metric that tracks public recognition, media coverage, and fan engagement across platforms. The Leemujin Service appearance is likely to add to that visibility as clips from the episode circulate on fan social media.

Why Leemujin Service Still Matters

In a music landscape where vocal performances are increasingly engineered and refined before reaching audiences, Lee Mujin Service occupies a specific and important space. Host Lee Mujin, himself a highly respected singer-songwriter, approaches each episode with the seriousness of a fellow musician evaluating peers rather than a MC managing a variety segment. His reactions carry weight because his opinion is earned.

The show's YouTube presence on the KBS Kpop channel has made it globally accessible, and the format travels remarkably well across language barriers — live music in a stripped-down setting communicates something that doesn't require translation. Episodes regularly attract international viewers who come for the specific artists and stay for the format.

For K-pop idols, it represents both a risk and an opportunity. The risk is self-evident — there is nowhere to hide on a platform built on transparency. The opportunity is equally clear — a strong Leemujin Service appearance creates a reference point that fans and industry observers return to when describing what an artist is actually capable of live. Lee Chaeyoung's Episode 225 is now that reference point for her.

Whether she returns to the show in the future or takes the energy of that performance back into fromis_9's group activities, the episode marks a moment in her 2026 that is worth noting. Four songs, live, with full commitment — and she delivered all of them.
