Background and recording
Jung revealed his desire to work with Sunwoo shortly after releasing of his first solo album One Fine Day. Collaborating only with men for the album, he expressed his desire to work with female musicians. He felt that the two could collaborate on a song in the tempo of allegretto. Initially, Sunwoo believed that Jung was just a "vocalist of an idol band". After listening to his album, she became aware of his abilities as a singer-songwriter."Empathy" was conceived as a result of the inspiration Jung and Sunwoo invoked between each other. Prior to meeting her, he wrote incomplete lyrics to "Hello" with her in mind. Also conveying the sentiment of wanting to participate in a song with Jung, Sunwoo wrote incomplete lyrics for "Fireworks". Within a month, she was called upon to collaborate with Jung, in which she deemed as "fate". The two agreed on a "double collaboration".
Jung and Sunwoo met in Hongdae, Seoul, at Sunwoo's record company MagicStrawberry Sound. They exchanged the lyrics they had written and proceeded in finalizing the songs. On writing "Hello", the two determined that it must be a "warm" track. Once agreeing on the theme and word choice for the song, the two first completed writing and recording the song. "Fireworks" was completed after Jung finished the composition and recording the bridge of the track on an electronic keyboard. He also provided guitar for both songs.
