One of a Kind is the second extended play by Loossemble. It was released on April 15, 2024 under CTDENM. The EP contains 8 tracks, including the lead single "Girls' Night".
On February 4, 2024, group member Hyunjin announced that the group was preparing for "comeback season"[1] and continued to tease the future release on fan messaging app Fab[2] until March 15, when 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.[3][4][5]
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.[6] On March 19th, the company posted on the group's fanclub site that the release date would be pushed back one day to the 15th.[7]
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.[8][9][10] 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[11]
