Many active performers attend music shows to promote their releases. But in 2021, we were surprised to see eight K-pop acts and groups return to these stages to promote their songs. For at least two years, all acts mentioned here did not attend a music show, though some may have continued to release music. Due to COVID-19, no live audiences were present for the stages.
Let’s take a look at their stages!
Highlight – Not The End

Highlight marked a return in spring with a flowery showcase of their first stage for Not The End on M Countdown, their first in three years and seven months. On the same broadcast, they also performed Sorry, an album cut from their third mini album, The Blowing.
