The last 2 members to file their injuctions, Vivi (24) and Hyunjin won their injuctions against the agency on May 9, 2023. It was announced on June 11, 2023 that the two members signed with CTDENM, a South Korean record label and entertainment agency established by 윤도연, BlockBerry Creative's former planning division director. On June 16, 2023, Go Won, Yeojin and Olivia Hye won their lawsuits to terminate their exclusive contracts with BlockBerry Creative, and was announced to have signed with CTDENM on July 5, 2023. Olivia Hye would also start promoting under her birth name, Hyeju (Hangul: 혜주). The group's name is a portmanteau of "Loona" and "assemble."
