Jang Dae-hyeon

Jang Dae-hyeon (장대현) took the long route from survival-show contestant to one of fourth-generation K-pop's steadier writer-performers. After Mnet's Produce 101 Season 2, he debuted in project group Rainz, then regrouped under Oui Entertainment before stepping into the leader role inside WEi.

That second chapter is where his profile sharpened. Dae-hyeon became one of the group's most reliable rap writers and concept anchors, taking credits across the Identity and Love series before co-writing and co-composing the 2026 single Save. He is not just the member who fronts introductions. He helps shape the records.

With WEi's group timeline now paused, his page reads less like an idol placeholder and more like a record of durable craft. The real throughline is authorship: survival-show grit, team leadership, and a songwriting track record strong enough to matter once the group cycle slows down.

Fans Also Ask

Is Jang Dae-hyeon the leader of WEi?
Yes. Jang Dae-hyeon is the leader of WEi, the six-member boy group launched by Oui Entertainment on October 5, 2020. He is also one of the team's core lyric writers, which gives him a bigger role than stage positioning alone suggests.
What group was Jang Dae-hyeon in before WEi?
Before WEi, Jang Dae-hyeon competed on Produce 101 Season 2 in 2017 and then debuted in project group Rainz later that same year. Rainz was short-lived, but the group gave him real public exposure before he re-entered the idol market under Oui Entertainment.
Did Jang Dae-hyeon write songs for WEi?
Yes. Jang Dae-hyeon has writing credits across WEi's catalog and received formal co-writer and co-composer credit on the 2026 single Save. His role inside the group has consistently extended beyond rap delivery into shaping concept language and song structure.
When did Jang Dae-hyeon debut?
Jang Dae-hyeon first debuted in 2017 after Produce 101 Season 2, then entered his longer-running chapter with WEi on October 5, 2020. That two-step path matters because it explains why his career reads as persistence rather than a single clean launch.
What happened to WEi in 2026?
In 2026, WEi's group timeline shifted into a pause as members moved toward individual schedules and military-era planning. For Dae-hyeon, that made the authorship side of his profile even more important, because his songwriting and leadership now carry more of his long-term identity.
