UNB's Daewon is the next member to drop an album trailer for 'Boyhood', and UNB also have an official D-1 fan service teaser video!


As you can see below, Daewon seems to be representing a 'healthy' boyhood, while Kijung took an innocent side and Ji Han Sol was a bad boy. The fan service teaser video reveals UNB's concept, which seems to be in all white.

Stay tuned for more UNB trailers until the group's debut on April 7!
