JINJIN is ASTRO’s leader and a rapper. His rhythmic delivery complements the group’s vocal melodies, and his individual recordings provide a separate space for his work as a performer and music creator.

Wave in my heart pairs JINJIN with YUNHWAY for the with KozyPop project. The official special clip presents the song apart from ASTRO’s group and unit catalog.

Born March 15, 1996, JINJIN debuted with ASTRO in 2016. The group’s releases provide the shared background for his solo work, while these individual recordings highlight his voice and musical direction outside the group arrangement.
