The song earned him his first music show trophy as a soloist a week later on SBS MTV's The Show. D-Day peaked at number five on South Korea's national Circle Album Chart and has shifted over 22,000 units domestically since its release.

## Background and recording

Kim participated in the second season of Mnet's survival reality series Produce 101 (2017), where contestants competed to become a member of the boy group Wanna One. He was eliminated from the competition in the third elimination round and finished in 29th place. After his stint on the program, Kim and five other former contestants signed a seven-month contract to promote together in a newly formed unit. The project group JBJ debuted that October. They released three mini-albums and embarked on concert tours in Asia. Kim performed a cover of Taemin's "Move" at the group's final concert, which led the CEO of his agency to believe he could debut as a soloist. Despite calls from fans for JBJ to extend their period of activities, the members' respective agencies failed to come to an agreement and the sextet disbanded the following April. The result left Kim feeling uneasy and he decided to travel to Japan with former bandmate Kenta to relieve stress.
Kim subsequently began working on solo music in early May and he lost 7 kg (15 lb) within a month in preparation for his debut record. He considered himself "more of a dancer than a singer" while in JBJ and decided to home in on his vocal abilities. He chose to drop his "cute" image to assert masculinity and sexiness, explaining that "I made the effort to show a new side of me. I hope many people recognize it." Kim took part in selecting the outfits utilized for the album photos. The mini-album was entitled D-Day after the term, which also serves as an abbreviation for "Dong-han Day".
Kim recorded songs with differing concepts to prioritize diverse compositions. He likened the album to a buffet, "offering a wide selection". Material for D-Day was recorded in the same studio that JBJ had used and Kim spent between four and five hours recording each song. Kim noted his difficulties singing the mini-album's eponymous opening track, describing it as "gentle, bright, and cute" and the "most adorable song" on the record. Korangi penned "Sunset", who had previously composed JBJ's "Call Your Name", and gave the song to Kim. "Ain't No Time" was recorded with Wooseok of Pentagon, though the two did not meet. Kim participated in crafting the song's choreography. He asked former JBJ bandmate Sanggyun to feature on "Record Me". Kim had originally recorded the rap verse and described the final product as more palatable. On the closing track "Night Call", Kim "sang as though I'm about to cry". He found the process strenuous; the recording session lasted 14 hours, which resulted in him injuring his vocal cords. The songs were mixed at the Team N Genius recording studio, except for "Record Me" that was completed at Studio Sean; the mini-album was mastered at 821 Sound.

## Music structure

   "It has a great beat and sounds exciting, so it was nice to choreograph. Even the title, 'Sunset', goes well with the summer season."
—Kim on choosing the lead single
Musically, D-Day is a dance album that sees Kim explore electronic music, R&B, hip hop, and balladry. It opens with the title track, an alternative hip-hop song. The song consists of a "refined and dreamlike" rhythmical beat accompanied with Kim's "boyish" vocals. He sings in a "sensual" voice on "Sunset", an electronic dance track. The chorus delivers an "explosive" bassline with "emotional" guitar riffs and "dreamy" synthesizers. A tropical-EDM and chill trap number, "Ain't No Time" expresses the narrator's desire to travel to an uninhabited remote island with a lover. Wooseok of Pentagon provides a rap on the track. "Record Me" is an R&B song where the lyrics express appreciation to fans for the "unforgettable love" JBJ received. It features a rap verse by Sanggyun. "Night Call" begins with Kim speaking over the phone. The song a mid-tempo ballad which conveys the fluttering feeling of a phone call between lovers before falling asleep.
