Hello. Next up is another cute Japanese girl group debuting at the Weverse concert. Please pay attention to the new Japanese girl group co-produced by LDH and HYBE. The group name is "MOONCHILD" and debuted on May 3rd. I'm waiting for the impression video of the MV "Don't Blow it!" that you watched.
