Loossemble

Loossemble (루셈블) brought five former LOONA members back into one project after the group’s legal break from Blockberry Creative. Formed by CTDENM, the lineup united HyunJin, YeoJin, ViVi, Go Won, and HyeJu around a name that fused Loona and assemble into a clean statement of intent.

That context mattered. Loossemble was never framed as a nostalgic side project. The group debuted on September 15, 2023 with the mini album Loossemble, then followed with One of a Kind and TTYL in 2024, proving there was still audience demand for this branch of the LOONA story as a working act rather than a one-off reunion headline.

The next chapter turned more uncertain. CTDENM announced the end of all five members’ contracts in November 2024, pushing the group into an indefinite hiatus while the members explored new options. Even so, Loossemble still carries weight inside the post-LOONA map because it showed how quickly these artists could rebuild identity, catalog, and fan focus outside the structure they left behind.
