At the Global Citizen Festival, BTS member Jungkook announced his next solo project. After a striking performance at the Golabl Cizen Festival 2023 in New York, the 'Seven' singer unveiled the first teaser of his upcoming project titled '3d'.

Shortly afterwards, BIGHIT MUSIC officially announced that “3D” was a new solo digital single featuring Jack Harlow. In their English statement, the agency wrote, “Jungkook’s second solo single, ‘3D (featuring Jack Harlow),’ is a pop R&B track with clever expressions of feelings toward an unattainable person from the perspectives of first, second, and third dimensions. Get ready to meet an even more mature side of Jungkook following ‘Seven (featuring Latto).’”
