On November 12, a source from DIA’s agency MBK Entertainment told Newsen, “DIA is planning a comeback next year in January and preparing for it.” Newsen reports that it’s planned that Jung Chaeyeon will be promoting with the group for the comeback.
DIA most recently made a comeback in June with their sixth mini album “Flower 4 Seasons” as a five-member unit without members Jung Chaeyeon and Somyi.

They’re still at it! Chaeyeon will be participating in these promotions. No news on Somyi if she’s participating or MBK officially announcing she left.
