Jang Dae-hyeon is a South Korean singer, dancer, former member of RAINZ and current member of WEi. He graduated from Shinjin Science and Technology High School.

He participated in the singing survival show "Produce 101 Season 2" and finished in 83rd place. However, after the show concluded, fans began petitioning MNet to create a project group with popular contestants outside of the Top 10. So, the Japanese agency KISS Entertainment took over the fan request.

He made his debut in October 2017 as RAINZ's rapper with their first EP, "Sunshine". The group signed a one-year contract and officially disbanded in October 2018, when they concluded the last group activities in Japan.

He returned to his agency, OUI Entertainment, and debuted as a solo artist in August 2019 with the single "Feel Good". Then, he re-debuted in October 2020 as WEi's leader, main rapper and vocalist with their first EP, "Identity: First Sight". They have enjoyed some popularity, especially in Japan.
