Composition
"Heart Burn" was composed and arranged by CobiCudi and Kyuwon 'Q' Kim. Sunmi participated in writing lyric for both the title track and the B-side track "Childhood". While having credit in music part for her B-side, Sunmi did not do it for the title song. In a press conference, she explained that she wanted to see how other producers perceived her by composing this track.

Sunmi considered her lastest work to be the daytime version of her previous single "Pporappippam". "Heart Burn" is described as a catchy dance and pop rock song, with an addictive melody that gives a "mysterious yet energetic vibe". The B-side "Childhood" is also a city-pop-inspired song from the 2004 movie The Notebook and has the same vibe as her other tracks like "Black Pearl", "Faded Love".

Music video


The music video for "Heart Burn" was filmed at Los Angeles. To show the atmosphere of the music video, Sunmi dyed her hair orange and added some freckles on her cheeks via makeup. The choreography, makeup, and costumes of the song were simplified as much as possible, as to make the MV purer. The point choreography was inspired by the hula dance form. Large fans were also served as a highlight of the music video.

The video's setting spans various locations and times, including 1966 Los Angeles, 1856 Texas, 1928 Bogota, and 1969 Tokyo. Sunmi plays the role of an immortal vampire who leaves a trail of dead lovers wherever she goes. By kissing her, all the men fell sick right after and died. At the end of the music video, she jumps, dances, and throws flower petals over the graves of the lovers she killed.
