JINJIN&ROCKY

Having established themselves as K-Pop mainstays in the late 2010s, South Korean boy band ASTRO began debuting their members in sub-units: following the 2020 debut of Moonbin & Sanha, Jinjin & Rocky formed the group's second sub-unit in early 2022. They debuted that January with the mini-album Restore: an energetic set featuring a guest appearance from Choi Yoojung, the project debuted at never seven on the Gaon charts.
