The girls played dodgeball with mirror images of themselves in "Happy" and ended their promotions on a high note. They invited 113 fans who made up the cheer team, the players team, and the reporters team and played dodgeball with the fans for about 2 hours. At the end of the event, fans got signed dodgeballs, and some lucky ones even ended up with the uniforms the girls were wearing.
Cosmic Girls said, "I think we got closer to our fans through the dodgeball match. We're always thankful to the fans who are always by our side protecting and supporting us."
