Loossemble
Loossemble (루셈블) is a South Korean girl group formed by CTDENM and composed of five former LOONA members: HyunJin, YeoJin, ViVi, Go Won, and HyeJu. The name merges Loona and assemble, defined by CTDENM as five members coming together as one.
After winning legal injunctions against Blockberry Creative in 2023, the five signed with CTDENM and debuted on September 15, 2023 with their self-titled mini album. Three projects followed: the debut EP (2023), One of a Kind (2024), and TTYL (2024).
In November 2024, CTDENM announced the end of all contracts. The group went on indefinite hiatus. In April 2025, Go Won stated during a livestream that the members do not want to re-debut under a new name but rather continue as Loossemble. Contract negotiations with an unnamed agency ended in May 2025 with no deal reached. YeoJin became the first member to launch solo activities, signing with MUMW Entertainment in January 2026.
Fans continue to support individual members while hoping for a group reunion.
