Kain

Kain was revealed as a member of ARGON on November 19, 2018. He made his debut with the group on March 11, 2019 with the single album "Master Key". The group presumably silently disbanded in late 2020, due to their prolonged inactivity and the lack of any further official announcements.

Since 2021, Kain, who professionally uses the name Junho, has worked as a backup dancer for various artists, including Hpresso, ENHYPEN, Red Velvet, and SF9.
