The agency dropped two teaser cuts of Yoo Seung Woo with the words, "Comeback photo 20160927 Yoo Seung Woo X Heize coming soon."

The cuts reveal the singer looking adorable in a snuggly sweater, round glasses, and a shy grin on his face!
I'm going to guess that this will be a sweet autumn duet that you can relax to, but it's still a wee bit early to tell. We'll have to find out when the collab track drops on September 27!
