On March 6, Kep1er’s agencies WAKEONE and KLAP Entertainment released an official statement announcing that Youngeun will be leaving the group. Following her departure, Kep1er will continue their activities as a six-member group.

Back in July 2025, the agencies announced that Youngeun was experiencing health issues and was advised by medical professionals to take sufficient time to rest and recover. She has been on hiatus since then.
