Previously, former LOONA members Heejin, Kim Lip, Jinsoul, and Choerry have been confirmed to sign with Modhaus. At midnight on April 1st KST, the agency revealed teasers of a new group comprising the four members. The teaser features the name ARTMS along with a photo of what looks to be 12 phases of a moon. See the full teaser below, which features a linked webpage with all associated social media accounts.
After nine of the members of LOONA was reported to have filed injunctions to suspend their contracts with Blockberrycreative, only Heejin, Kim Lip, Jinsoul, and Choerry were determined to have won their lawsuits.
