Kim Chaewon (LE SSERAFIM Leader): Profile, Biography, Career and Facts

Kim Chaewon is a South Korean singer best known as the leader of LE SSERAFIM, the five-member girl group under Source Music, a HYBE label. To newer K-pop fans, she’s instantly recognizable for her sharp bob-era visuals, steady vocals and confident stage presence. Long-time fans, though, know her career started years before LE SSERAFIM.

Before becoming the leader fans know today, Chaewon competed on Produce 48 and debuted as a member of IZ*ONE. That experience gave her something pretty valuable before starting again with a new group: years of performing, recording and promoting at a professional level.

Here’s a closer look at Kim Chaewon’s profile, biography, career, LE SSERAFIM role and major achievements.

Born on August 1, 2000, in Seoul, Chaewon grew up in South Korea and attended Hanlim Multi Art School, one of Seoul’s well-known arts-focused schools.

Her career officially began in 2018, but her path wasn’t an instant one-group debut. She first had to prove herself through one of K-pop’s most competitive survival programs.

Biography: Early Life and Education

Chaewon developed an interest in performing while she was still young and eventually pursued formal training with Woollim Entertainment.

Rather than becoming publicly known through a traditional trainee reveal, she entered the spotlight through Mnet’s Produce 48 in 2018. The program brought together Korean trainees and Japanese idols competing for places in a temporary girl group.

She represented Woollim Entertainment and steadily built support throughout the competition. Chaewon eventually placed 10th in the final episode with 238,192 votes, earning one of the 12 positions in IZ*ONE.

That result changed the direction of her career almost immediately.

Career: From IZ*ONE to a New Beginning

IZONE officially debuted on October 29, 2018, with the mini album COLORIZ and its title track “La Vie en Rose.”

During her time with IZ*ONE, Chaewon gained extensive experience performing in South Korea and Japan. Her clear vocal tone and increasingly confident stage presence made her particularly noticeable as the group’s career progressed.

She also began getting involved creatively. During the IZONE era, Chaewon received music credits including participation in the composition of “WithOne” and lyrics for “Slow Journey.”

IZ*ONE completed its planned activities in 2021. For Chaewon, though, that wasn’t the end of her idol career. It became the beginning of a major reinvention.

In March 2022, Source Music confirmed plans for a new girl group featuring former IZ*ONE members Kim Chaewon and Sakura. Soon after, the name LE SSERAFIM was officially revealed.

And this time, Chaewon would return as a leader.

Debut With LE SSERAFIM

LE SSERAFIM officially debuted on May 2, 2022, with their first mini album FEARLESS and the title track of the same name. Source Music currently lists the group as consisting of Sakura, Kim Chaewon, Huh Yunjin, Kazuha and Hong Eunchae.

The group name itself is an anagram of “I’M FEARLESS,” matching LE SSERAFIM’s recurring themes of confidence, ambition and moving forward without being controlled by outside expectations.

For Chaewon, the debut felt noticeably different from her previous image. Her styling became bolder, her performance approach sharper and her presence more commanding. It wasn’t simply another debut—it showed a more mature version of an idol fans had already watched for years.

Since FEARLESS, LE SSERAFIM’s discography has expanded through projects including ANTIFRAGILE, UNFORGIVEN, EASY, CRAZY and HOT, along with later releases.

Awards and Nominations

Most of Chaewon’s major awards are shared with LE SSERAFIM rather than presented to her individually.

The group picked up significant recognition almost immediately. At the 2022 Melon Music Awards, LE SSERAFIM won both the Hot Trend Award and Best Performance – Female.

International recognition followed as the group expanded beyond Korea. One of their biggest milestones came at the 2024 MTV Video Music Awards, where LE SSERAFIM won PUSH Performance of the Year for “EASY.”

They also performed “CRAZY” and “1-800-hot-n-fun” during the 2024 VMAs, another sign of how far the group’s global reach had grown.

Kim Chaewon’s Role in LE SSERAFIM

Chaewon serves as LE SSERAFIM’s leader, but her contribution isn’t limited to introducing the members or speaking during interviews.

She acts as one of the group’s vocal anchors while also handling demanding choreography and maintaining strong live-stage presence. Because she had already experienced several years of idol promotions before LE SSERAFIM debuted, she entered the group with practical experience that naturally fits a leadership position.

What makes her interesting to watch is that she doesn’t perform like she’s trying to dominate every second. Instead, she can switch between controlled vocals, playful expressions and much sharper performance energy depending on the song.

That versatility has become a big part of her identity.

Final Words

Kim Chaewon’s career has already gone through two very different chapters. She first became known through Produce 48 and IZ*ONE, then successfully started again as the leader of LE SSERAFIM.

That second chapter arguably shows her growth most clearly. The quiet, polished trainee viewers met in 2018 has developed into a confident performer capable of leading one of K-pop’s internationally active girl groups.

For FEARNOT, Chaewon is more than simply “the leader.” She’s a vocalist, performer and experienced idol whose career keeps evolving without losing the qualities that made fans notice her in the first place.

And considering how much she has changed since Produce 48, watching what she does next is part of the fun.
