She joined Biscuit Entertainment (비스킷엔터테인먼트) and, in late 2021, she participated in Mnet's survival show "Girls Planet 999", where she ranked 5th. During the final episode of the show, she was confirmed as part of the resulting project group and was set to perform for 2 and a half years.
She made her debut in January 2022 as KEP1ER's main vocalist and dancer with the mini album "First Impact". After the departure of Kang Ye Seo in May 2024, she also became the group's maknae.
In June 2024, the agencies WakeOne Entertainment (웨이크원엔터테인먼트) and Swing Entertainment (스윙엔터테인먼트) decided to continue the group, so she renewed her contract. However, in July 2025, she went on hiatus to focus on her mental health recovery and never returned to the lineup. She officially left on March 6, 2026.
