Jaeun

Jaeun originally debuted in the boy group INX under the stage name Win. The group was only active for one year and released two digital singles before disbanding in 2017. After INX's lawsuit, now as Jaeun, he joined a new company sometime in 2018.

He was then revealed as the fifth member of the then upcoming six-member boy group called ARGON on November 22, 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.
