Sehyeon

Sehyeon (세현), born Kim Sehyeon, is a South Korean singer who entered DKZ during the group's 2022 rebuild and quickly became part of the lineup that carried the act through its final era. He joined DKZ just as the team shifted from cult-favorite momentum to a broader mainstream push, giving the group a steadier vocal center during the Cupid breakout and the releases that followed.

That timing matters. The 2022 rebrand from Dongkiz to DKZ became one of the sharper reset stories in fourth-generation boy group history, and Sehyeon arrived right at the inflection point. He helped anchor the post-rebrand lineup across Chase Episode 2. Maum, Chase Episode 3. Beum, and the later REBOOT cycle, while the group built a stronger live and fan-event presence under DONGYO ENTERTAINMENT.

In April 2026, Dongyo confirmed that DKZ would conclude group activities on May 31 while the members remained with the company for individual work. That leaves Sehyeon at the start of a new phase rather than at a hard stop. He exits the group chapter with a real fandom base, official solo-facing visibility through his Instagram account, and a discography tied to one of the more memorable late-stage small-agency boy group turns of the decade.
