Yang Da Il and Wendy reveal still cuts of Wanna One's Park Woo Jin from 'That Summer'

Brand New Music had said, "We are certain that this single will be a successful summer single to continue the legacy from San E and Raina's 'A Midsummer Night's Sweetness'." From the still cuts, it looks like it may be a little less happy than "A Midsummer Night's Sweetness" was.
