“Became Calm” is a b-side track from MAMAMOO’s most recent mini album, “Yellow Flower.” The song was co-composed by Hwasa herself, and she also penned its lyrics. The music video was directed by Park Woo Sang, who is also the track’s co-composer. [

As she described how the video came to be, Hwasa explained that it had started off as a pet project, and that they originally intended to only make a video for the first half of the song. The project ended up growing bigger than they thought, resulting in the released video.
