The program "Queendom 2" is a comeback battle between 6 trending girlgroup acts, in order to "determine the real number one" when all 6 of them release their singles at the same time. The program will last for 10 weeks, from March 31, 2022, to June 2, 2022. The program features 1 opening performance, 3 preliminary contests and 1 live comeback stage from each act. The Comeback Singles, which are newly produced songs, of the 6 acts will be released on May 27, 2022, at 12:00 (KST). The digital points accumulated for the Comeback Singles and live votes for the comeback stages on the final episode, together with the accumulated points from the 4 preliminary performances, are the keys to determine the final winner. The winning act will have a comeback show only for them, showing the new song and their other hit songs, arranged however they want it. The comeback show will be broadcasted on Mnet. This season is hosted by Taeyeon herself.
