Sungho is the eldest member and main vocalist of BOYNEXTDOOR, the KOZ Entertainment boy group known for its relatable, everyday storytelling and easy-listening sound. Born Park Sung Ho on September 4, 2003, in Wonju, South Korea, Sungho joined KOZ Entertainment as its first-ever trainee and made his official debut on May 30, 2023, with the single album WHO!. As BOYNEXTDOOR's main vocalist, he is celebrated for his warm, emotionally rich tone, which anchors fan-favorite tracks across releases like WHY.., HOW?, 19.99, No Genre, and The Action. Beyond his vocal talent, Sungho is recognized by fans and members alike as the group's steady, dependable energizer, someone whose mature, logical approach keeps BOYNEXTDOOR grounded even during their busiest promotional cycles. His broad shoulders and calm confidence earned him the affectionate nickname 'Shoulders,' while members also call him 'Top Gun' for his sharp, reliable presence both on stage and behind the scenes. Off camera, Sungho reveals a softer, more sentimental side: he is a devoted cinephile who admires directors like Christopher Nolan and Park Chan-wook, enjoys jazz music, loves animals, and spends his free time cafe hopping and taking photographs around Seoul. Despite his composed public image, he has admitted to being surprisingly afraid of bugs and prone to genuine, unfiltered emotion. As BOYNEXTDOOR continues to expand globally with world tours and chart-topping comebacks, Sungho remains one of the group's most beloved members, admired for a voice and personality that fans describe as both grounding and quietly tender.
Story
Biography
Sungho is the eldest member and main vocalist of the South Korean boy group BOYNEXTDOOR, a six-member act formed by KOZ Entertainment, the HYBE sub-label founded by producer Zico. Born Park Sung Ho on September 4, 2003, in Wonju, Gangwon-do, Sungho was KOZ Entertainment’s very first trainee, joining the label years before BOYNEXTDOOR’s official lineup was even announced. That head start gave him time to hone the warm, stable tone that fans now recognize as one of the group’s signature vocal colors.
Sungho made his official debut on May 30, 2023, alongside Riwoo, Jaehyun, Taesan, Leehan, and Woonhak with BOYNEXTDOOR’s first single album WHO!. As main vocalist, he anchors the group’s title tracks and ballads, and he has continued to grow through releases like WHY.., HOW?, 19.99, No Genre, and The Action. Known within the group as its dependable “energizer,” Sungho balances a mature, plan-ahead personality with a surprisingly soft and sentimental side that fans have come to adore.
Off stage, Sungho is a devoted movie lover with a particular fondness for directors like Christopher Nolan, Martin Scorsese, and Park Chan-wook, and he enjoys jazz and classical music between schedules. He loves animals, is left-handed, and wears contact lenses in public due to poor eyesight. Despite his broad-shouldered, tough-looking image — which earned him the nickname “Shoulders” — he has openly shared that he is afraid of bugs and can be quite emotional. Members call him “Top Gun,” a nickname that reflects both his sharp instincts and his caring, big-brother presence within BOYNEXTDOOR.
