Kang Ye Seo is a South Korean singer, dancer, actress, former member of CUTIEL (큐티엘; stylized as CutieL), BUSTERS (버스터즈) and KEP1ER (케플러), and current member of MADEIN (메이딘 / メイディン). She graduated from Lila Art High School and is enrolled in the theater program at Dongguk University.

In 2010, she made her debut as a child actress in the MBC drama "Golden Fish", and Big Star Entertainment decided to create a child group formed with several actors. A few months later, she debuted as one of the original members of CUTIEL with their first digital single "Cutie Carol" before she left in 2013 to focus on her acting career.

In 2019, she joined JTG Entertainment (제이티지엔터테인먼트) and was selected to join their girl group BUSTERS as the new vocalist when another member dropped out. She re-debuted in July 2019 with the digital single "Starlight". The group faced several incidents in the following months and went on an indefinite hiatus. During that time, she decided to resume her acting career and left the group.

In 2021, she participated in the survival show "Girls Planet 999" (걸스 플래닛 999), landing a place in the resulting project group and was supposed to perform for two and a half years from their debut date. She re-debuted as KEP1ER's vocalist and maknae with their first mini album, "First Impact", and was managed by WakeOne (웨이크원) and Swing Entertainment (스윙엔터테인먼트).

In July 2024, her contract ended, and she returned to her agency, 143Entertainment (143엔터테인먼트), where she was immediately placed as a new member of LIMELIGHT, which had debuted the previous year. The group was rebranded as MADEIN, new members were added, and she re-debuted in September 2024 with their first EP, "Rise."

On December 26, 2025, she suspended her activity as a member of MADEIN.
