About OnlyOneOf

OnlyOneOf (often shortened to OOO) is one of K-pop's most artistic and experimental boy groups. They're known for blending alternative R&B, art pop, synth-pop, deep house, and contemporary dance with storytelling that explores identity, desire, loneliness, and human emotion in ways that are rare in idol music. They debuted on May 28, 2019 with the mini album dot point jump and the double title tracks "savanna" and "time leap."
