Described as a Bible-influenced concept through the singer's understanding as a story, the extended play was executively produced by Jo Yeong-cheol and Lee Min-soo, with lyricist Kim Eana penning most of the record's lyrics.

The extended play also saw Gain collaborating with several South Korean rappers, namely Jay Park and Dok2, while G.Gorilla, Mad Clown and singer Wheesung contributed lyrically to the release.

[1] Upon its release, Hawwah received positive reviews from critics for its "fine" tune, further complimenting Gain for crossing the "extreme[ness]" in sexuality.

According to APOP Entertainment, Gain's agency, the EP would be promoted by two lead singles, and released digitally at 12:00 am KST on the aforementioned day.

Featuring a lot of genres and moods, its content was described as a Biblical portrayal of Eve with emphasis on temptation, duality and self-confiding.

Based on jazz piano and melodies, the funky track shows an impressive combination of Gain's vocals and Jay Park's rapping.

"[11] "Paradise Lost", another lead track from the album,[12] is inspired from the same-titled epic poem written by English poet John Milton.

[13] The single reunited composer Lee Min-soo and lyricist Kim Eana, who have worked together with Gain since her first solo EP Step 2/4 (2010).

About her snakelike choreography in the music video, the singer commented, "Snakes caught my eyes as I studied about the concept of Hawwah.

"[17] Billboard magazine reviewed the song favorably, saying that "it opened with a nice balance of classical elements and modern embellishments."
