NU'EST has opened a concept page for their upcoming comeback.
The boys are coming back with their 7th mini-album 'The Table', and they've now dropped a concept page. The page shows a car driving up to a house (restaurant?) marked at 'The Table,' parking, and then there are footsteps as the passenger walks toward 'The Table'.
Check it out here and get ready for their comeback on October 21st.
