Much to the delight of DIA and the audience members, IOI showed up at the comeback showcase which was broadcast live via 'V' on June 14, alighting the venue with their presence.
IOI told DIA members, "Congrats on your comeback, DIA. Please show IOI some love as well." Se Jung added, "Unfortunately, Yeon Jung couldn't be with us. We also can't stay until the end because of our schedules but congratulations."
Jung Chae Yeon, who is a member of both DIA and IOI, returned, "Thank you for coming here despite being so busy. We gained a lot of energy thanks to your support. IOI unit, fighting!"
Good luck to both groups!
