Girl group 3YE is finally making a comeback.

3YE will release its second single, "OOMM," at 6 p.m. on Sept. 17 and begin full-pledged activities.

3YE has been raising fans' expectations by introducing various contents ahead of its full-fledged comeback. In particular, the dance teaser video released by GH Entertainment on Sept. 16 drew attention with some of the strong concept performances that 3YE will show through "OOMM activities." The scene of a 3YE wearing gas masks and powerful choreography against the backdrop of a prison makes viewers surprised.

Third Eye's new song "OOMM" is the acronym for "Out of My Mind," and the song "Wooziq" and "Genie" by the group Wanna One and Golden Child, which have recently made their debut as DJ.

The harmony between confident lyrics and the members' charismatic rapping and vocals has completed a dramatic development that has never been heard in existing girl group music.

Meanwhile, "3YE 2nd Digital Single OOMM" will be released on various music sites and on Sept. 17 at 6 p.m.
