Background and release
On March 15, 2023, CTDENM announced via the group's official social media account that the upcoming second EP would be titled One of a Kind and was to be released on April 16.

The release date was immediately met with backlash from fans, as April 16, 2024 was to coincide with the 10th anniversary of the sinking of MV Sewol. On March 19, the company posted on the group's fanclub site that the release date would be brought forward one day to April 15.

The track list was released on April 12, with the music video teaser and highlight medley following over the course of the next two days. The EP and music video for the lead single "Girls' Night" were released at the same time at 6:00 PM KST on April 15, 2024.
