Cheetah released a teaser video for its new single "So Sorry" on its official SNS in the afternoon of Aug. 14.

"So Sorry" is a song that sends a message of support to past me not to give up because I'm doing well enough even if it's dark in front of me.

Cheetah participated in writing and composing the song herself, and the groovy drums and melodies mingled together around the guitar melody to fill the emotional atmosphere of the song.

Cheetah's new single, "So Sorry," will be released on music sites before noon on Aug. 17.
