Seventeen has dropped the final teaser for leader S.Coups.
The group is preparing a mysterious '2017 Seventeen Project' for their comeback, and Chapter 1 revolves around the theme 'Alone'. 'Prime Number' is also an ongoing motif in Seventeen's teaser series 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. S.Coup's number is, fittingly, '17'.
The boys have also dropped a teaser image with the words "I left my heart in San Francisco", a famous song by Tony Bennett. They will be coming back on the 22nd.
