Woollim Entertainment, DRIPPIN's agency, unveiled its fourth track prequel "Nostalgia" on its debut album "Boyager" at midnight on Oct. 23 on its official SNS channel.

In the video clip released, DRIPPIN drew attention by appearing in a black suit through a long line of curtains. The sensuous and dreamy visual beauty added to the members' manly eyes acting with a strong aura drew enthusiastic responses from fans waiting for their debut.

"Nostalgia" is an active and energetic song that reinterprets the words "A yearning for the past" and "Nostalgia" from the perspective of "DRIPPIN," showing the willingness to return to the memory rather than simply missing the happy moment.
