Girl group Mamamoo WHEE IN will release its second solo album, "Soar."

WHEE IN will release its second solo album "Soar," including the title track "GOODBYE," at 6 p.m. on various music sites.

The title track, "GOODBYE," is the second time that WHEE IN and Jung Key have collaborated since "I'm on a burden," and captures the feelings of one person who has no choice but to say "Let's end up breaking up" after countless considerations."

The soft piano melody and emotional melody line blend WHEE IN's soft but hard vocals, reminding risers of the parting moment they buried deep in their memories.

In particular, the song, which is played thickly with the delicate yet appealing voice of WHEE IN, is increasingly emotional and at the end of the song, one can feel the explosive high-pitched and sad sensibilities of WHEE IN.

In addition, the music video, which will be released, is a drama "Ties," which focuses on mournful lyrics, and evokes the emotions of those who watch the movie as it features a beautiful but mysterious song by WHEE IN.

In addition, actor Song Chae-Yoon elaborates on the complex emotions that he has come to like his art teacher, giving him a sense of immersion in the story.

The upcoming album, "Soar," an extension of the first digital single "magnolia," is an attractive album that allows one to feel the deep musicality of a WHEE IN, who expresses the petals fluttering in the wind by the time the magnolia is wide and losing again.

Including the title track "GOODBYE," WHEE IN's solo debut track "EASY" and "GOODBYE" which took her first step as a solo artist, were included.

Furthermore, WHEE IN has been receiving positive reviews for recording the artistic quality of the album as well as participating in painting works and dress styling that can be seen in music videos and jacket photos.

As such, WHEE IN plans to show its true value as an emotional vocalist through its emotional new song "GOODBYE," which marks the start of autumn.

Meanwhile, WHEE IN's second solo album "Soar" will be released on various music sites at 6 p.m. on Sept. 4, and will also be available at offline music stores.
