Rocket Punch will make a comeback with its third single "Boom" on Sept. 6, the girl group's agency Woollim Entertainment on Wednesday.

It will be the girl group's first music release in a year, following its second single "Flash" released in August last year.

The teaser video released Wednesday showed bright pink-colored heart balloons flashing in the background, with the title of the single and its release date announced after.

Three members from the girl group, Yeonhee, Suyun and Juri, recently participated in cable network Mnet's girl group survival program "Queendom Puzzle." Yeonhee landed in sixth place, with 358,059 total points and is set to be a part of the project group EL7Z U+P.

Six-member girl group Rocket Punch debuted in 2019 with its first EP "Pink Punch" and its lead track, "Bim Bam Bum."
