In the KPop industry the meaning of the word “comeback” is slightly different from the way it’s used in the West. It can, but does not exclusively refer to an artist who has been on a long hiatus returning to the music scene. Most of the time it means a KPop group or solo artist, who previously released singles, is back again with a new album/single and promoting them by 1st performing the song on a music TV Show (=doing a “comeback stage”).
