Seungkwan

Boo Seungkwan, known mononymously as Seungkwan, is a main vocalist and the official MC of SEVENTEEN. Born on January 16, 1998, on Jeju Island, South Korea, he joined Pledis Entertainment as a trainee in 2013 and debuted with SEVENTEEN in May 2015. His warm, powerful vocal tone and natural entertainment instincts made him one of the most popular members during the group's pre-debut period.

As a main vocalist, Seungkwan delivers some of SEVENTEEN's most emotionally compelling performances. His voice carries a plaintive quality even in upbeat songs — a natural expressiveness that makes his singing feel genuinely felt rather than technically executed. His passionate approach to performance, combined with an impressive range, has earned him consistent recognition as one of the strongest vocalists in the third-generation K-pop idol landscape.

Seungkwan's role as SEVENTEEN's official MC adds another dimension to his value within the group. He is frequently cited as one of the best MCs in K-pop for his ability to read a room, generate natural conversation flow, and pivot between humor and sincerity with uncommon ease. In group variety content, he often drives the narrative, keeping energy high while ensuring every member gets moments to shine. His Jeju Island origins — regularly referenced in his own comedic self-presentation — give him a charming regional identity within a group of Seoul-area members.

His partnership with DK as a vocal duo is one of SEVENTEEN's most celebrated internal dynamics, with the two main vocalists complementing each other's styles — DK's theatrical brightness against Seungkwan's warmer intensity — to create genuinely moving live vocal showcases. His emotional authenticity, both on and offstage, has made him one of the group's most beloved members among long-term fans.
