All-round musician JUNNY has released a teaser image of the new single "nostalgia" with JAYB on its official SNS on the afternoon of December 21st, raising the expectations of music fans.

The teaser image contains the scenery outside the window viewed from the running train. The sunset sky across the bridge and the city that looks like a silhouette contain a deep sensibility that goes well with the single name "nostalgia."

Through this "nostalgia," Junny will make a quick comeback to the music industry a month after the single "HIDE & SICK" was released last month. Juni, who revealed his presence with the double title album Inside the Sovere Mind in June this year, is drawing attention by actively performing music activities until the end of the year.
