Born Boo Seung-kwan on January 16, 1998, in Busan, South Korea, his early life took root on Jeju Island, where his family relocated when he was very young, and where he was subsequently raised. He grew up in a nurturing, non-celebrity environment alongside his two older sisters. From his elementary school years, Seungkwan displayed a burgeoning talent for singing, actively participating in various children's song festivals held across the island. It was during one of these performances that his vocal promise caught the attention of a teacher, who recorded his rendition of a song and subsequently uploaded the video online. This seemingly small act would become a pivotal moment in his burgeoning career path.

The online exposure garnered by this video led to significant industry interest, including an initial offer from JYP Entertainment, which Seungkwan ultimately declined. However, his undeniable talent soon caught the eye of Pledis Entertainment, leading to his casting in June 2012, at the age of 14. Following this discovery, the aspiring artist, then 15 years old, made the significant move from Jeju Island to Seoul to fully commit to his training. He spent three years and two months as a dedicated trainee under Pledis Entertainment, honing his skills, having notably auditioned with Kim Bum-soo's "Last Love." Concurrently with his intensive training, Seungkwan pursued his education at Seoul Broadcasting High School, a specialized institution geared towards entertainment, from which he successfully graduated in 2016.

Even before his official debut, Seungkwan began to build early recognition within the entertainment industry. He was a prominent figure on the pre-debut reality show "Seventeen TV," which aired from 2013 to 2014, offering fans a glimpse into the trainees' development. Further cementing his presence, he performed alongside other Pledis trainees at the prestigious 2014 SBS Awards Festival, showcasing his growing stage presence and vocal abilities to a wider audience. These early experiences laid the groundwork for his eventual breakthrough. [edit]

Seungkwan debuted as the main vocalist of SEVENTEEN on May 26, 2015 with the extended play "17 Carat." His powerful high notes and emotive delivery quickly defined the group's vocal identity. He belongs to the Vocal Team and, in 2018, formed the special subunit BSS (BooSeokSoon) with Hoshi and DK. BSS debuted in March 2018 with the viral single "Just Do It," highlighting his comedic timing and energetic stage presence. Beyond group activities, he became a prominent variety show personality, appearing regularly on programs such as "Unexpected Q," "Prison Life of Fools," and "The Devil's Plan," earning the Rookie Award at the 2018 MBC Entertainment Awards for his work in music/talk categories. He has released multiple successful original soundtracks (OSTs) that charted well in South Korea. In February 2024, he debuted solo with the single "Dandelion," marking his official solo debut. He expanded into education by becoming a university lecturer on K-pop in 2024, sharing industry insights with students. On December 11, 2025, he launched his YouTube variety show "Bib-Bob-Boo," with Stray Kids' Lee Know as the first guest. As of 2026, he remains an active SEVENTEEN member. [edit]
