Kim Sun Ho, known professionally as Roel, is a South Korean singer, dancer and former member of ARGON. He used to be part of the broadcasting club during middle school and high school and even wanted to become an announcer. However, he made his debut in 2019 as lead vocalist of the group managed by MSH Entertainment with their 1st single album, "Master Key", charting at number 70 on the Gaon Album Chart. In April, they launched their 1st Japan Live "Master Key" showcase in Tokyo, which kicked off a three-month Japanese promotional period for the album. Later that year, they released their 1st EP, "Go Forward: Wide Dream", with the single "Give Me Dat" rising to #54 on the charts. Sadly, after that, the group saw a lack of promotion and activities and while no official announcement was ever made, they quietly disbanded in early 2021. Not much is known about him after the disbandment so it is uncertain if he remains in the industry or not.
