It was released on November 29, 2018, by RBW as the lead single from the group's eighth extended play (EP), Blue;s. A "comforting" breakup song, "Wind Flower" was produced by Kim Do-hoon and Park Woo-sang and written by them and Mamamoo member Moonbyul.

The Japanese version of the song was released on February 6, 2019, as their second Japanese single.

Background and release
In 2018, Mamamoo embarked on their Four Seasons, Four Colors series of albums, releasing the commencement single "Paint Me" in January, their sixth EP Yellow Flower in March, and their seventh EP Red Moon in July. On November 7, the group was announced to be coming back with their eighth EP, Blue;s, and a new song. A music video teaser for the single was released on November 22. "Wind Flower" was released digitally alongside its parent EP on November 29, 2018.

The Japanese version of "Wind Flower" was released alongside the B-side "Sleep Talk" as Mamamoo's second Japanese-language single on February 6, 2019. It was later included on the group's debut Japanese album 4colors, which was released in August 2019. A remix of the original Korean version, subtitled the "Dramatic Version", was released on September 15, 2021, as the 17th track on Mamamoo's first compilation album, I Say Mamamoo: The Best.

Composition
Musically, "Wind Flower" is a K-pop and R&B breakup song. The original song runs for three minutes and 56 seconds, while the Japanese version lasts an additional second. Both versions are composed in the key of C major and at a tempo of 114 BPM. The Korea Herald remarked that with "Wind Flower", "Mamamoo gives the exhausted theme of romance gone wrong a groovy makeover" yet still "anything but a cliche." The publication also stated that the song, and the rest of the EP, "bring R&B to the mainstream K-pop scene" and that the genre has "found its best advocate in the K-pop scene." "Wind Flower" has also been called a song that "captures the sentimental sensibility" of the group and displays the "lonely and faint feelings which a person has after separation from a lover."

The Japanese b-side "Sleep Talk" has been described as an "impressive song... that will make [one] feel excited again", as opposed to the typical "J-pop-oriented catchy songs and heart-pounding ballads".
