The first episode of the new Wanna One reality show aired on March 30. The boys flew over to Jeju Island for the show, and sunbae idol YoonA made a special appearance with a video message.
YoonA informed that Wanna One has "homework" they need to complete on the island and that was for them to make a CF for 'Innisfree'; the 'Green Tea Seed Serum' to be exact. Following the message, the producers provided the boys with props for filming.
Watch Wanna One turn into CF directors on the first episode of 'Wanna One Go in Jeju'.
