DK

DK (도겸), born Lee Seok-min (이석민), is one of the defining voices inside SEVENTEEN and the leader of BSS under Pledis Entertainment. He debuted with the group in May 2015 and became central to its vocal identity through a bright upper register, muscular live control, and emotional clarity that travels cleanly from arena pop to ballad work.

His range is broader than the standard idol-vocalist tag. DK helped drive SEVENTEEN releases from 17 Carat to SEVENTEENTH HEAVEN, fronted BSS's 2023 commercial hit Second Wind, and built a credible second lane in musical theatre with Xcalibur. He also kept a solo thread moving through the 2024 single "MERRY-GO-ROUND" and the 2025 Resident Playbook OST "It's You."

By 2026, the picture is even clearer. DK is still a core SEVENTEEN vocalist, but he is also operating as a fashion-facing talent through Bally and magazine work, while the duo project with Seungkwan adds another performance format to the stack. Few male idols of his generation balance group scale, vocal credibility, and crossover polish this cleanly.
