Narrated by this season's nation's producer representative Lee Seung Gi, the teaser begins with, "Nation's producer-nims, here are the faces you voted for." Mnet then surprises fans of the past 'Produce' series by bringing together IOI and Wanna One in one place, for one very nostalgic, sentimental, a slow-mo pan of the past winners and the groups they formed. 

The nation's effort to create the top Korean-Japanese girl group in Mnet's upcoming 'Produce 48' begins on June 15 at 11 PM KST! Will you be tuning in?
