Park Min Joon, formerly known as Hanseul, is a South Korean singer, dancer and former member of MYTEEN (마이틴).
He made his debut in 2017 as the group's lead vocalist, rapper and maknae with their first EP, "MyTeen Go!". As some of the members began entering singing survival competitions like "MIXNINE" and "Produce X 101", they could not perform with a complete lineup.

So, in August 2019, The Music Works (뮤직웍스) decided to disband the group. After the announcement, he chose to quit the entertainment industry.
