Jung In will comeback with her 4th mini-album on October 17th.

Her title song "Autumn Man" (tentative translation) is written from a girlfriend's point of view, sung to the man who becomes lonely in autumn. This song was arranged by Primary, and will feature a blues rhythm and retro concept. Jung In herself produced this album, and all 5 of the tracks are written by the singer songwriter.

In the teaser released on October 14th, Jung In's 11-year boyfriend Jo Jung Chi starred as the "autumn man." Anchorwoman Lee Keum Hee narrated the teaser video, and parodied a human documentary narration.
