Comeback meaning in K-pop
컴백 · say “KUM-bak”
A comeback is any new release and the promotions that come with it, not a return after a long break.
What does Comeback mean?
When a group releases a new album or single, fans call it a comeback even if the last one was a few months ago. The period usually includes a music video, music show stages and fan events.
Agencies announce comebacks with a date and a schedule of teasers. See what is coming next on the comeback calendar.
Example
"When is the next BTS comeback?"
