Hwaa

"Hwaa" (Korean: 화(火花); lit. "Anger (Spark)"; stylized in all caps) is a song recorded by South Korean girl group (G)I-DLE, released on January 11, 2021, by Cube Entertainment and Republic Records as the lead single of the group's fourth extended play, I Burn. The song is written by member Soyeon and co-produced by Pop Time. The inspiration for the song came to Soyeon when member Shuhua once said 'winter girl' in a conversation. She took the idea and created the concept of a woman trapped in winter. Musically, it is a moombahton, dark pop, dream pop and synth-pop track with oriental instrumentations, and contains double entendres about fire and flowers. The song was the last single released by (G)I-DLE as a sextet, before Soojin's departure from the group in August 2021.

Commercially, "Hwaa" became (G)I-DLE's first top-five hit on the Gaon Digital Chart—peaking at number four—and became their first chart-topper on the component Download Chart. It additionally peaked at number five on K-pop Hot 100, number six on World Digital Songs and number 173 on Global Excl. U.S. chart. An English and Chinese version of the song was released as a digital single two weeks later on January 27, 2021. A remix version of the song by Dimitri Vegas & Like Mike was released on February 5.
