DK is the next member to hint at Seventeen's new Project Chapter 1, 'Alone', with a trailer of his own.
The trailer series first began with Vernon, then went on to Mingyu, Junghan, and now DK, with additional Seventeen members also making appearances toward the end of each trailer to suggest possibly pairing the members in groups of two. In DK's trailer, Seungkwan appears at the end.
'Prime Number' is also an ongoing motif in Seventeen's teaser series so far, as fans have to enter the prime number seen in each member's trailers on the group's official website in order to be able to access their teaser images.
What are you making of Seventeen's teaser trailers so far? Stay tuned for more, leading up to their full comeback!
